TECHNICAL FIELD

[0002] This document pertains generally, but not by way of limitation, to an irrigation recirculation system that includes multiple subsystems for recycling and filtering rain and irrigation water for use in an irrigation system. More particularly, but not by way of limitation, this disclosure relates to systems, devices, and methodologies for recycling, filtering, and using the water in an irrigation system for fire suppression, and prevention.

BACKGROUND

[0003] Water irrigation systems can range in size from being in someone’s backyard to under an entire football field. A conduit system placed underground terminates in discharge nozzles that are referred to as sprinkler heads. The sprinkler heads dispense the water from the conduits. Sometimes, the sprinkler heads are located above the ground. Other times, such as in applications such as sports fields, the sprinkler head is only extended from under the ground to above the ground during use of the irrigation system. The sprinkler heads are positioned apart from one another and rotate to ensure full coverage of a spray area.

[0004] Under the ground, the conduit terminating at the sprinkler head extends to a water source. Groups of sprinkler heads, referred to as zones, will have a single input conduit such that when water flows to a first zone, all of the sprinkler heads in that zone dispense water. A valve or valve system can then be utilized so that the different zones operate independently of one another. A control system may thus be utilized with a timing circuit to operate different zones of sprinkler heads at different times during the day.

[0005] The water source for such irrigation systems can be an above the ground storage tank or below the ground storage tank. Water is received within a tank from an external water supply such as a city water tower or city water filtration facility and replenished accordingly. Examples of external water supplies include, but are not limited to any municipal water supply, a village, city, or state water supply, or any other water supply provided by any third party that supplies the water. Such irrigation systems are installed by digging into a yard or field, placing the system into place and then coupling the system to the city water system. These systems are maintained by the installer who cleans the system and performs routine maintenance.

[0006] Often irrigation systems are utilized in dry climates where the ground must be watered often to keep plant life and grass healthy and green. These dry climates may be prone to fires, including wild fires, that result in catastrophic damage to dwellings, including single family homes, barns, sheds, apartment buildings, office buildings, and the like.

OVERVIEW

[0007] In an effort to reduce or minimize the amount of water that needs to be received from an external water supply, water recirculation systems can be utilized. These water recirculation systems attempt to take water from secondary sources to supplement the water supply in storage units so that less water needs to be used from the external water supply. Secondary sources can include, but are not limited to rain water from gutters on a roof, water from other rain gathering devices, underground water saturated in the soil, and standing rainwater or irrigation water in the irrigation area.

[0008] In gathering such water, care is taken in cleaning the water. Debris and other solids in an irrigation system can have significant consequences. Such debris can cause clogs and blockage in conduits and the sprinkler heads that can cause damage to the irrigation system. In particular, to discharge blockage, pumps are forced to provide additional pressure, resulting in wear on the pump. The higher than expected pressure also results in uneven distribution of water across an irrigated area. The end result can be unscheduled maintenance and early replacement of irrigation equipment, causing frustrations for irrigation system users.

[0009] Additionally, municipalities have regulations regarding water quality, regardless of whether the water is to be used for irrigation or otherwise. Specifically, testing is done for bacteria such as e-coli, and unsafe contaminants such as lead or mercury, to prevent unsafe contaminations that can be harmful to a community. Thus, filtration, cleaning, and disinfecting of water is a useful component of the irrigation recirculation system.

[0010] Certain systems for keeping water clean can have multiple disadvantages.

For example, filters that simply catch debris can become blocked, reducing effectiveness and increasing maintenance. While cleaning of above the ground storage tanks can be accomplished, above the ground storage tanks are unsightly and prone to water evaporation and freezing without additional protection. Cleaning a below the ground storage tank can be disruptive to irrigation system owners and time consuming for installers and maintainers.

[0011] This document describes, among other things, an irrigation recirculation system that can include multiple filtering subsystems for filtering water prior to distribution to the sprinkler heads. This can include an initial filter element located within a basin that intakes recirculated water. The filter element can separates solids, such as dirt and debris, from water such as through turbulence. For example, by striking the filter, a change in direction of the water occurs resulting in the water moving faster than the solids. This can help cause the solid to sink to the bottom of the basin for removal. [0012] Additional filtering subsystems can include a storage tank such as formed from a perforated membrane that can allow the passage of ground water and can inhibit or prevent the passage of debris. Also described is a distribution tank subsystem that can use a low-pressure waste water pump concurrently with a high-pressure pump that stirs the water within a distribution tank such as to facilitate the movement of solids to a waste water reservoir. Another subsystem uses a control system of the irrigation recirculation system to control one or more valve elements and a high-pressure pump such as to push a mixture of high pressure air and water through the sprinkler head such as to dislodge debris without requiring using an air compressor. As a result of one or a combination of these filtering devices or methods, a microfilter is also able to be utilized prior to the sprinkler head discharge. In all, these subsystems can help increase or maximize recirculated water to be utilized by the irrigation system while providing extensive filtration prior to discharge with reduced or minimal maintenance and upkeep costs.

[0013] In addition, because the filtration of the debris from the recirculated water, this water may be utilized for the purposes of extinguishing fires. Specifically, by utilizing a control system that includes at least one sensor for detecting the presence of a fire, the control system may actuate both a sprinkler head pump and dwelling pump to deliver the water collected by the system from the dwelling and from underground adjacent the dwelling to the dwelling. Thus, if a wild fire is detected by the control system either or both the dwelling pump and/or sprinkler head pump may be utilized to deliver the filtered water to extinguish the fire.

[0014] This Overview is intended to provide non-limiting examples of the present subject matter - it is not intended to provide an exclusive or exhaustive explanation. The Detailed Description below is included to provide further information about the present apparatuses and methods.

DETAILED DESCRIPTION

[0027] The present application relates to devices, systems, and methods for recycling water, such as rainwater, by a water recirculation system. The Figures are all related to various examples of a water recirculation system, water recirculation subsystems, and methodologies related to filtering and cleaning water within the water recirculation irrigation system. While not shown, other examples using similar systems, devices, and methodologies are contemplated.

[0028] Fig. 1 illustrates a top schematic view of an irrigation recirculation system

100, in accordance with at least an example of the disclosure. In the example of Fig. 1, the irrigation recirculation system 100 is utilized in association with water recirculation area 102. In the example of Fig. 1, the water recirculation area includes a dwelling 104. The dwelling can include but is not limited to a home, garage, shed, bam, apartment, office building, or the like. While in this example a dwelling 104 is presented on the water recirculation area 102, in other examples of implementation, a dwelling 104 is not presented in the area 102. In such examples the area includes but is not limited to a football field, soccer field, outdoor track, baseball field, other sports or hobby related field and open area, stadium, fair ground, concert ground, crop field, farmland, or the like.

[0029] In Fig. 1, a water collection system 106 is provided. The water collection system 106 can include gutters 108 on the dwelling that catch the rain or other water from the roof of the dwelling.

[0030] The gutters 108 can include a filter element 110 that cover the gutters 108 such that rain and other fluid going into the gutter pass through the filter element 110. The filter element 110 is structured from a material such that the mesh or other structure is permeable to fluid and inhibits or prevents solids from penetrating through the structure formed material. In an example, the material of the filter element 110 is made from spun nylon.

[0031] When a rain storm occurs and leaves and other debris are carried with the rain water into the gutters 108, the filter element 100 can help ensure that the leaves and debris remain outside the gutters 108 as the rain water flows into the gutters 108. The leaves and debris are then blown away by wind or swept away by a person cleaning the gutters at a later time. In this manner, the filter element 1 10 provides an initial filtration of the collected water to be recycled or recirculated through the irrigation recirculation system 100.

[0032] In an example, the water collection system 106 can also include tile elements 114, such as positioned about the dwelling 104, such as can help inhibit or prevent the flow of water toward the foundation of the dwelling. One or more other water collection structures such as rain barrels, standing water pumps, sump pumps, or the like are also contemplated by this disclosure. Such structures of the water collection system 106 can be used to direct water toward a drainage system 116.

[0033] The drainage system 116 can include a water intake conduit 118 that receives water from the collection system and directs the water into a fluid flow conduit 120 that defines a fluid flow path. The fluid flow conduit 120 conveys the water to a water collection basin 122. In an example of the drainage system, multiple basins 122 are positioned throughout the water recirculation area 102. A filter element 124 is disposed within each collection basin 122 for removing solids from the collected water. An example of a collection basin 122 is described in detail with reference to Fig. 2.

[0034] In Fig. 1, in an example, the collection basins 122 are interconnected through a series of the fluid flow conduits 120. The fluid flow conduits 120 can run underground, such as generally parallel to the top surface of the ground. The fluid flow conduits 120 can provide a fluid flow path from the basins 122 to a storage system 126. In this manner, as the water flows along the fluid flow path, the water can be filtered in one or multiple basins 122 prior to being conveyed to the storage system 126. In an example, the collection basins 122 need not be interconnected with fluid flow conduits 120 and instead an individual fluid flow conduit 120 can extend from a collection basin 122 directly to the storage system 126 such as with only a single passage through a single filter element 124.

[0035] The storage system 126 can intake all of the filtered water flowing from the basins 122 through the fluid flow conduits 120. An example of a storage system 126 is shown and described in detail with relation to Fig. 4. In Fig. 1, an interceptor tank 128 can receive the filtered water from the fluid flow conduits 120. From the interceptor tank 128, water can be conveyed through a storage conduit 130 to a storage tank 132.

[0036] Storage tank 132 can be fluidly connected, such as via a distribution conduit

133, and can provide water into a distribution tank 134. From the distribution tank 134 water is either conveyed through an irrigation conduit 136 to an outlet nozzle 138, or through a waste water conduit 140 to a waste water reservoir 142. In an example, the outlet nozzle 138 is a sprinkler head. In an example, the waste water reservoir 142 is a municipal reservoir that directs water to a municipal sewer or water system.

[0037] Figs. 2A-2B illustrate an example of a collection basin 122 that can be utilized in the drainage system 116 of the irrigation recirculation system 100 of Fig. 1. The collection basin 200 can include a housing 202 such as disposed vertically in the ground and can provide an interior cavity 204 that holds a volume of water conveyed from a water collection system. The housing 202 in an example can be made from metal or hard plastic to provide an impermeable barrier between the dirt and the water contained in the interior cavity 204 of the housing 202.

[0038] The collection basin 200 can include a fluid flow conduit inlet 208 that directs water into the basin and a fluid flow conduit outlet 210 that takes water from the basin 200 disposed through the housing 202. The fluid flow conduits 208 and 210 are examples of the fluid flow conduits 120 described in regard to Fig. 1. The collection basin 200 also optionally includes an overflow conduit outlet 212 for conveying overflow water from the interior cavity 204.

[0039] A removable filter element 214 is disposed within the interior cavity 204 of the housing 202. The filter element 214 is generally centrally located within the basin, extending vertically from adjacent a bottom end 216 to a top end 218. The filter element 214 extends in a plane generally perpendicular to the fluid flow path. The filter element 214 also extends such a length and the inlet fluid conduit is angled in such a way that water flowing into the fluid flow conduit inlet 208 strikes a portion of the filter element 214.

[0040] In an example, the filter element 214 is made from a material such that the structure of the filter element is penetrable to fluid and inhibits or prevents solids from penetrating through the filter structure. This material is shown in Fig. 2A and at least 1/2 inch think. In one example the material is between 1/2 inch and 2 inches in thickness. The material comprises interwoven threads of varying diameters of at least 1/8 inch diameter. In one example the interwoven threads have a diameter in a range between 1/8 inch diameter and 1/4 inch diameter. Specifically, the vertical filter structure when struck laterally by a water and solid mixture above a threshold velocity causes both the water and solid to change direction, or bounce off the filter. In this manner, the solid within the water does not become lodged within the filter material. Once the water and solids change directions, the solids through gravity sink to the bottom of the basin 200. Meanwhile, the standing water on top of the solids is then below the threshold velocity and thus permeates through the material. In an example, the material of the filter element 110 is made from spun nylon, such as to form a three dimensional mesh that allows fluid to penetrate but inhibits solids larger than openings in the mesh from penetrating through the filter structure.

[0041 ] A frame 220 is secured to the interior cavity 204 to receive the filter element

214. The frame 220 includes spaced apart brackets 222, 224 secured along the interior cavity 204 that are connected with a crossbar bracket 226 adjacent the bottom end 216 of the basin 200. The brackets 222, 224, and 226 in an example are u-shaped brackets that receive the filter element 214. In an example, when the filter element 214 is inserted into a filter position in the frame 220, the filter element 214 slides within the brackets 222, 224 until engaging the crossbar bracket 226. Once inserted in the filter position, the brackets 222, 224, and 226 prevent downward and lateral movement of the filter element 214 when the filter element 214 is struck by the water and solid mixture.

[0042] A removable lid element 228 covers the top end 218 of the basin 200. The lid element 228 includes a lid filter element 230 extending across the interior area of the lid element 228. In an example, the lid filter element 230 is made of spun nylon. By being removable, the lid element 228 provides access to within the basin 200 for changing of the filter element 214 or removal of solids at the bottom end 216 of the basin 200 through vacuuming or other means. In an example, during a 60-day period between 70,000-75,000 gallons of water can be filtered through the filter element 214 resulting in the removal of 3-5 gallons of unclean water as the bottom end 216 of the basin 200.

[0043] Fig. 3 illustrates an example of a method 300 of filtering solids in a basin, such as the basin 200 of Fig. 2. At 302, water flows through a fluid flow conduit inlet at a velocity above a threshold velocity. At 304, the water from the inlet strikes the filter element with the velocity above the threshold velocity. At 306, the water striking the filter element changes direction as a result of the material of the filter element. At 308, solids separate from the water because when the water changes direction, the water moves faster than the solids in the water. At 310, as a result of gravity, the solids sink to the bottom end of the basin. At 312, water that had struck the filter element and is now flowing below the threshold velocity permeates through the filter element and to the fluid flow conduit outlet.

[0044] In other words, as a result of turbulent flow cause by the water striking and bouncing off the filter element, solids dislodge from the incoming water and sink to the bottom end of the basin. After initial contact, the water seeks the path of least resistance as a result of water pressure and permeates through the filter element. In this manner, filtered water flows over the top of water contaminated with dirt, debris and other solids to the fluid flow conduit outlet. Therefore, when maintenance occurs, instead of replacing the filter element, one need only open the lid element remove the filter element and remove the dirt, debris and other solids settling at the bottom end of the basin. Such removal can optionally be done with a vacuum or other cleaning device.

[0045] Fig. 4 illustrates a schematic representation of an example of a storage system 400 that can be the storage system 126 of the irrigation recirculation system 100 of Fig. 1. The Fig. 4 representation is not to scale and is presented in such a manner for clarity of explanation. The tanks and conduits discussed can be located about an entire recirculation area as described in the example of Fig. 1.

[0046] The storage system 400 includes an inlet fluid flow conduit 402 that directs water received from basins in the recirculation area and conveys the water to an interceptor tank 404. The interceptor tank 404 has an interior cavity 406 that is accessible from above the ground level 408 by a removable lid 410.

[0047] The interceptor tank 404 is in fluid communication with a waste water conduit 412 that can include a waste water check valve element 414. Water is conveyed from the interceptor tank 404 though the waste water conduit 412 to a waste water reservoir 416 when the waste water check valve element 414 is actuated. In an example, the waste water reservoir 416 is a municipality water or sewer system.

[0048] The interceptor tank 404 additionally is in fluid communication with a storage tank conduit 418 that has a valve element 420 that controls the conveyance of water to a storage tank 422. The valve element 420 when actuated either allows or prevents the flow of water from the interceptor tank 404 to the storage tank 422.

[0049] In operation, the interceptor tank 404 serves as a holding tank for filtered water received from the basins. This allows testing of the water in the interceptor tank 404 for contaminants prior to conveyance to the storage tank 422. In particular, the interceptor tank 404 can be accessed through the removable lid 410 and tested for contaminants such as e-coli, lead, mercury, or the like. If levels are considered unsafe, the water can then be conveyed to the waste water reservoir 416, or disinfected in the interceptor tank 404. After disinfection, the water can be tested again, for example, until the water is shown to be safe. [0050] During testing, when the water in the interceptor tank 404 is tested as safe, the valve element 420 in the storage tank conduit 418 is actuated to allow water to be conveyed to the storage tank 422. In this manner, during testing for contaminants and disinfection, water within the storage tank 422 can still be used for irrigation by the irrigation system.

[0051] The storage tank 422 receives water from the storage tank conduit 418 and includes a generally rectangular frame 424 having open side walls that surround and open interior cavity 426. The rectangular frame 424 and interior cavity 426 can be surrounded and enclosed by a membrane 428. In an example, the membrane comprises a range of between 3500-4000 square feet (sq. ft.) of material.

[0052] The membrane 428 can include an opening 430 such as for receiving the storage tank conduit 418 and can include perforations 432 disposed therethrough. As a result of the material of the membrane and the size and shape of the perforations 432, when the ground 434 surrounding the storage tank 422 is saturated with ground water, the ground water is able to permeate through the perforations 432 and into the storage tank 422 while solids such as dirt particles are prevented from entering the interior cavity 426 of the storage tank 422. Specifically, during the excavation process for installing the storage tank, natural tunneling is provided to convey water saturated in the ground 434 to the storage tank 422. In an example, the ground or soil adjacent the storage tank is at or over 94% saturated with water when water is conveyed through the perforations 432. Thus, between the collection system and the storage tank 422 approximately 400-2000 gallons of water are harvested by the irrigation recirculation system.

[0053] In an example, as shown in Fig. 4, a secondary membrane 436 can also include perforations 438 and can surround and enclose the membrane 428 that encloses the frame 424. In this example, a pocket 440 is formed between the membrane 428 and secondary membrane and filled with abrasive material 442. In one embodiment, the abrasive material 442 is a combination of rock and sand. The abrasive material 442 acts to filter solids and debris that make it through the perforations 438 of the secondary membrane 436. The abrasive material 442 prevents such solids from entering the interior cavity 426 of the storage tank 422.

[0054] The storage tank 422 also includes a discharge tank conduit 444 positioned adjacent the bottom of the storage tank 422 and disposed through openings 446 and 448 of the membrane 428 and secondary membrane 436. The discharge tank conduit 444 conveys water from the storage tank 422 to the distribution tank 450. In all, the irrigation recirculation system can have an overall flow rate through the system of between 600-650 gallons per minute.

[0055] The distribution tank 450 has an interior cavity 452 that receives water from the storage tank 422 via the discharge tank conduit 444. The distribution tank 450, similar to the interceptor tank 404 extends above ground level 408 and has a lid element 454 that is removable to allow access to the interior cavity 452 of the distribution tank 450. In this manner, one can test the water within the distribution tank 450 for contaminants such as e- coli, lead, and mercury prior to use to determine if disinfection or discharge of water needed.

[0056] The distribution tank 450 is in fluid communication with a waste water conduit 456 for directing water from the distribution tank 450 to the waste reservoir 416. The waste water conduit 456 of the distribution tank 450 has a waste water pump 458 for pumping water from within the interior cavity 452 of the distribution tank to through the waste water conduit 456.

[0057] The waste water pump 458 of the distribution tank 450 is considered a low pressure, high volume pump. In particular, the waste water pump pumps the water with a pressure is a range from 40-70 pounds per square inch (psi). This is approximately in a range of 40-50 gallons per minute. Thus, if water from within the interior cavity 452 needs to be discharged into the waste water reservoir 416, the waste water pump actuates to direct the water to the waste water reservoir accordingly.

[0058] The distribution tank 450 also receives and is in fluid communication with a supplemental water conduit 460. The supplemental water conduit 460 has a valve element 462 therein and receives water from a supplemental water source 464. In an example, the supplemental water source is pre-filtered water from a municipal water supply.

[0059] The supplemental water of the supplemental water source 464 is provided to ensure if a condition within the storage system 400 occurs where the amount of recycled water is insufficient for the needs of the irrigation system for any reason, filtered water is still available. Such reasons can include but are not limited to drought, system malfunction, extended testing and disinfection periods, or the like, filtered water is still available for the irrigation system.

[0060] A distribution tank sensor 466 within the distribution tank 450 determines the water level within the distribution tank 450. The sensor 466 provides signals to a control system 468 that contains circuitry and is electrically connected to the valve element 462 to automatically actuate the valve element 462 of the supplemental water conduit 460 to supply the filtered water when water levels are determined to be insufficient. Additionally or alternatively, this supplemental filtered water can be added to the distribution tank 450 to dilute contaminated water to a point where the concentration of contaminants within the discharged water meets requirements of a municipality.

[0061] The distribution tank 450 is in fluid communication with a sprinkler head conduit 470 that includes a sprinkler head pump 472 for pumping the water through the sprinkler head conduit 470 to discharge nozzles 474 of an irrigation system 475. In an example, the sprinkler head pump is a turbine pump capable of providing high pressure through the discharge nozzles 474. In an example, the discharge nozzles 474 are sprinkler heads. The pump 472 can include a high-pressure pump that operates at in a range from 100 pounds per square inch (psi) to 225psi. Thus, fluid flows through the sprinkler head conduit 470 at a speed in a range of 85-210 gallons per minute.

[0062] A distribution valve element 476 is disposed within the sprinkler head conduit 470 that when actuated determines whether water is distributed to a first zone 478 of discharge nozzles 474, a second zone 480 of discharge nozzles 474, or another zone. In an example the distribution valve element 476 is a valve manifold that provides water to the different zones as desired. Additionally or alternatively, water can be distributed to multiple zones simultaneously.

[0063] A microfilter 482 is also disposed within the sprinkler head conduit 470 for a final filtration of water prior to discharge through the discharge nozzles 474. The microfilter 482 is able to last with only periodic maintenance as a result of the filtering and cleaning of water throughout the irrigation recirculation system.

[0064] The storage system 400 thus provides water collection, filtration, and self cleaning capabilities. In an example the storage system 400 stores between 5,000 and 742,000 gallons of water for distribution and filtration.

[0065] Fig. 5 illustrates a method of cleaning a distribution tank 500. At 502, water is provided to a distribution tank. At 504, a waste water pump conveys the water from the distribution tank. At 506, a sprinkler head pump stirs the water in the distribution tank by conveying water to a sprinkler head conduit. At 508, the waste water pump conveys the stirred water from the distribution tank to the waste water reservoir. In this manner, the distribution tank is self-cleaned within the irrigation system.

[0066] Fig. 6 illustrates an example of a control system 600 that can be utilized for operating the irrigation recirculation system of Fig. 1 and is an example of the control system 468 described in relation to Fig. 4. The control system 600 is in communication with electrical components 602 of the irrigation recirculation system. These components 602 include system valve elements 604, including at least valve elements of the storage tank conduit, distribution tank conduit, waste water conduit, and sprinkler head conduit. The components 602 also include pumps 606, including at least the sprinkler head pump and the waste water pump. The components 602 additional include system sensors 608, including at least the distribution tank sensor. [0067] The control system 600 also includes a user interface 610 that includes inputs 612 for controlling the electrical components 602 of the irrigation system such as the valve elements and pumps. These inputs 612 allow both manual control of such electrical components 602 and programing such that the control system 600 automatically actuates the electrical components 602. To this end, the control system 600 includes timing circuitry 614 for opening and closing valve elements 604 such as the distribution valve, and pumps 606. In this manner, the timing circuitry 614 determines when water is distributed to different zones of the outlet nozzles and when the pumps 606 actuate for cleaning of the distribution tank.

[0068] The control system 600 also includes water level actuation circuitry 616.

The water level actuation circuitry 616 receives signals from at least one sensor in the distribution tank indicating the height of the water in the distribution tank. Based on the signals the water level actuation circuitry receives, the circuitry actuates a supplemental water valve element to convey water from a supplemental water source into the distribution tank until a desired water level is detected.

[0069] The control system 600 additionally includes weather station circuitry 618 that includes the one or more sensors 608. The one or more sensors 608 used by the weather station circuitry 618 may include temperature sensors, humidity sensors, moisture sensors, motion sensors, pressure sensors, or the like that detect weather based characteristics. The weather station circuitry 618 may also utilize a transponder, interlink (Figure 7), communication device, or the like to communicate with weather computer based applications, weather based webpages, or the like. An algorithm, look-up table, or the like, may then be used by one or more processors (Figure 7) using the detected characteristics and/or weather based information received to determine the amount of rainwater in a given environment, or anticipated for a given environment over a predetermined period. Then,

[0070] Based on the amount of rainwater anticipated over a predetermined period of time, the one or more processors may communicate with the electrical components 602 and timing circuitry 614 to override electromechanical features. For example, in one embodiment, the rainwater level of the underground storage system is such that it exceeds a threshold amount and the waste water pump of the pumps 606 is configured to drain water out of the distribution tank to get the water level below the threshold level. However, the weather station circuitry 618 determines based on weather based characteristics detected, received, obtained, or the like, that no additional rain for one week is anticipated. As a result, the weather station circuitry 618 is configured to operate, override and/or prevent the waste water pump from reducing the water level in the distribution tank in anticipation that no additional rainwater supply will be available in the foreseeable future.

[0071] Alternatively, in another example, when the storage tank does not exceed the threshold level, but is determined to be close to the threshold level and the weather circuity 618 determines heavy rain will occur within a predetermined time period such as 24-hours, the weather station circuitry 618 instructs the pumps 606 to remove water from the storage tank despite not being above the threshold limit. In this manner, the storage tank is prepared to receive the heavy rainfall, preventing potential overfilling of the storage tank or the continuous operation of the pumps 606 during the storm to remove rainwater from a storage tank. Thus, wear on the electrical components is reduced.

[0072] Method examples of the control system described herein may be machine or computer-implemented at least in part. Some examples may include a computer- readable medium or machine-readable medium encoded with instructions operable to configure an electronic device to perform methods such as described in the above examples. An implementation of such methods may include code, such as microcode, assembly language code, a higher-level language code, or the like. Such code may include computer readable instructions for performing various methods. The code may form portions of computer program products. Further, in an example, the code may be tangibly stored on one or more volatile, non-transitory, or non-volatile tangible computer-readable media, such as during execution or at other times. Examples of these tangible computer- readable media may include, but are not limited to, hard disks, removable magnetic disks, removable optical disks (e.g., compact disks and digital video disks), memory cards or sticks, random access memories (RAMs), read only memories (ROMs), or the like.

[0073] FIG. 7 illustrates a schematic showing system 700 that is an example of the control system 600 of the irrigation recirculation system 100 of Fig. 1. The system 700 can include local device 701, user interface 702 (where interface 610 is an example of such an interface), display 704, interlink 706, central device 708, central device database 710, and expert device 712. Local device 701 can include processor 714, volatile memory 716, static memory 718, and network device 720.

[0074] Local device 701 can be any computing device, such as a handheld computer, for example, a smart phone, a tablet, a laptop, a desktop computer, or any other computing device including information processing and storage capabilities and communication capabilities. Local device 701 can include processor 714, volatile memory 716, and static memory, which can be connected by wire or other electrical conduit within local device 701 and can be configured to receive information, process information, output information, and store information. The information can be temporarily stored on volatile memory 716 and can be relatively permanently stored on static memory 718. In some examples, configurations of these components within local device 701 can be considered machine readable medium.

[0075] The terms“machine readable medium” may include any medium that is capable of storing, encoding, or carrying instructions for execution by the device and that cause the device to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions.

[0076] User interface 702 can be any input and/or output device. For example, user interface can be a monitor, keyboard, and mouse in an example. In other examples, user interface 702 can be a touch screen display. Display 704 can be a display for displaying output from local device 701 and in some examples can receive input and transfer input to local device 701 (for example a touch screen display).

[0077] Central device 708 can be a remote device similar in configuration to local device 701, but located remotely from local device 701.

In some other examples, interlink 706 can be a local area network (LAN), wide area network (WAN), and internet protocol (TCP/IP) connections. Local device 701 can be similarly connected to interlink 706 (either through a wired or wireless connection). In some examples, network device 720 can connect local device 701 to interlink 706. Central device 708, central device database 710, and expert device 712 can be connected to interlink 706 in a similar manner.

[0079] In operation of some examples, system 700 can be configured to perform steps of the methods discussed herein and in some examples may perform steps based on a program stored in volatile memory 716 or static memory 718, where results of the analysis are stored in either volatile memory 716 and/or static memory 718 can be displayed on display 704 and/or transmitted to user interface 702, central device 708, central device database 710, and/or expert device 712.

One of local device 701, central device 708, and expert device 712 can segment the image to develop a 3D shoulder model.

[0080] Similarly, system 700 can be configured to perform steps of each method discussed herein.

[0081] Fig. 8 illustrates an example of a method of cleaning a sprinkler head 800.

At 802, a distribution valve element is closed to prevent water from a first zone of sprinkler heads from being conveyed to a second zone of sprinkler heads. At 804, water is conveyed from a distribution tank by a sprinkler head pump to the first zone of sprinkler heads. At 806, the sprinkler head pump stops conveying water from the distribution tank to the first or second zones of sprinkler heads.

[0082] At 808, a distribution valve element is opened simultaneously with the water not being pumped from the distribution tank such that water from the first zone is conveyed to from the first zone to the second zone. This conveyance also causes the formation of air pockets within both the first and second zones. At 810, after water is conveyed from the first zone to the second zone, the sprinkler head pump actuates to start pumping water from the distribution tank to both the first and second zones. This forces the air pockets out of the sprinkler heads in both the first and second zones dislodging any debris in those sprinkler heads. In an example, the ratio of air to water forced out of the sprinkler heads in a given period of time is approximately 50% air and 50% water. In an example, the period of time is in a range between 30-40 seconds. In this manner, methodology for self-cleaning the sprinkler heads of the irrigation system is provided.

[0083] Fig. 9 illustrates an example irrigation recirculation and fire extinguishing system 900. In one example, the system 900 of Fig. 9 includes the storage system 400 of Fig. 4. To that end, the Fig. 9 representation is not to scale and is presented in such a manner for clarity of explanation. The tanks and conduits discussed can be located about an entire recirculation area as described in the example of Fig. 1.

[0084] The storage system 900 includes an inlet fluid flow conduit 902 that directs water received from basins in the recirculation area and conveys the water to an interceptor tank 904. The interceptor tank 904 has an interior cavity 906 that is accessible from above the ground level 908 by a removable lid 910.

[0085] The interceptor tank 904 is in fluid communication with a waste water conduit 912 that can include a waste water check valve element 914. Water is conveyed from the interceptor tank 904 though the waste water conduit 912 to a waste water reservoir 916 when the waste water check valve element 914 is actuated. In an example, the waste water reservoir 916 is a municipality water or sewer system.

[0086] The interceptor tank 904 additionally is in fluid communication with a storage tank conduit 918 that has a valve element 920 that controls the conveyance of water to a storage tank 922. The valve element 920 when actuated either allows or prevents the flow of water from the interceptor tank 904 to the storage tank 922.

[0087] In operation, the interceptor tank 904 serves as a holding tank for filtered water received from the basins. This allows testing of the water in the interceptor tank 904 for contaminants prior to conveyance to the storage tank 922. In particular, the interceptor tank 904 can be accessed through the removable lid 910 and tested for contaminants such as e-coli, lead, mercury, or the like. If levels are considered unsafe, the water can then be conveyed to the waste water reservoir 916, or disinfected in the interceptor tank 904. After disinfection, the water can be tested again, for example, until the water is shown to be safe.

[0088] During testing, when the water in the interceptor tank 904 is tested as safe, the valve element 920 in the storage tank conduit 918 is actuated to allow water to be conveyed to the storage tank 922. In this manner, during testing for contaminants and disinfection, water within the storage tank 922 can still be used for irrigation by the irrigation system. [0089] The storage tank 922 receives water from the storage tank conduit 918 and includes a generally rectangular frame 924 having open side walls that surround and open interior cavity 926. The rectangular frame 924 and interior cavity 926 can be surrounded and enclosed by a membrane 928. In an example, the membrane comprises a range of between 3500-4000 square feet (sq. ft.) of material.

[0090] The membrane 928 can include an opening 930 such as for receiving the storage tank conduit 918 and can include perforations 932 disposed therethrough. As a result of the material of the membrane and the size and shape of the perforations 932, when the ground 934 surrounding the storage tank 922 is saturated with ground water, the ground water is able to permeate through the perforations 932 and into the storage tank 922 while solids such as dirt particles are prevented from entering the interior cavity 926 of the storage tank 922.

[0091] In an example, as shown in Fig. 9, a secondary membrane 936 can also include perforations 938 and can surround and enclose the membrane 928 that encloses the frame 924. In this example, a pocket 940 is formed between the membrane 928 and secondary membrane and filled with abrasive material 942. In one embodiment, the abrasive material 942 is a combination of rock and sand. The abrasive material 942 acts to filter solids and debris that make it through the perforations 938 of the secondary membrane 936. The abrasive material 942 prevents such solids from entering the interior cavity 926 of the storage tank 922.

[0092] The storage tank 922 also includes a discharge tank conduit 944 positioned adjacent the bottom of the storage tank 922 and disposed through openings 946 and 948 of the membrane 928 and secondary membrane 936. The discharge tank conduit 944 conveys water from the storage tank 922 to the distribution tank 950. In all, the irrigation recirculation system can have an overall flow rate through the system of between 600-650 gallons per minute.

[0093] The distribution tank 950 has an interior cavity 952 that receives water from the storage tank 922 via the discharge tank conduit 944. The distribution tank 950, similar to the interceptor tank 904 extends above ground level 908 and has a lid element 954 that is removable to allow access to the interior cavity 952 of the distribution tank 950. In this manner, one can test the water within the distribution tank 950 for contaminants such as e- coli, lead, and mercury prior to use to determine if disinfection or discharge of water needed.

[0094] The distribution tank 950 is in fluid communication with a waste water conduit 956 for directing water from the distribution tank 950 to the waste reservoir 916. The waste water conduit 956 of the distribution tank 950 has a waste water pump 958 for pumping water from within the interior cavity 952 of the distribution tank to through the waste water conduit 956.

[0095] The waste water pump 958 of the distribution tank 950 is considered a low pressure, high volume pump. In particular, the waste water pump pumps the water with a pressure is a range from 40-70 pounds per square inch (psi). This is approximately in a range of 40-50 gallons per minute. Thus, if water from within the interior cavity 952 needs to be discharged into the waste water reservoir 916, the waste water pump actuates to direct the water to the waste water reservoir accordingly.

[0096] The distribution tank 950 also receives and is in fluid communication with a supplemental water conduit 960. The supplemental water conduit 960 has a valve element 962 therein and receives water from a supplemental water source 964. In an example, the supplemental water source is pre-filtered water from a municipal water supply.

[0097] The supplemental water of the supplemental water source 964 is provided to ensure if a condition within the storage system occurs where the amount of recycled water is insufficient for the needs of the irrigation system for any reason, filtered water is still available. Such reasons can include but are not limited to drought, system malfunction, extended testing and disinfection periods, or the like, filtered water is still available for the irrigation system.

[0098] A distribution tank sensor 966 within the distribution tank 950 determines the water level within the distribution tank 950. The sensor 966 provides signals to a control system 968 that contains circuitry and is electrically connected to the valve element 962 to automatically actuate the valve element 962 of the supplemental water conduit 960 to supply the filtered water when water levels are determined to be insufficient. Additionally or alternatively, this supplemental filtered water can be added to the distribution tank 950 to dilute contaminated water to a point where the concentration of contaminants within the discharged water meets requirements of a municipality.

[0099] The distribution tank 950 is in fluid communication with a sprinkler head conduit 970 that includes a sprinkler head pump 972 for pumping the water through the sprinkler head conduit 970 to discharge nozzles 974 of an irrigation system 975. In an example, the sprinkler head pump is a turbine pump capable of providing high pressure through the discharge nozzles 974. In an example, the discharge nozzles 974 are sprinkler heads. The pump 972 can include a high-pressure pump that operates at in a range from 100 pounds per square inch (psi) to 225psi. Thus, fluid flows through the sprinkler head conduit 970 at a speed in a range of 85-210 gallons per minute.

[00100] A distribution valve element 976 is disposed within the sprinkler head conduit 970 that when actuated determines whether water is distributed to a first zone 978 of discharge nozzles 974, a second zone 980 of discharge nozzles 974, or another zone. In an example the distribution valve element 976 is a valve manifold that provides water to the different zones as desired. Additionally or alternatively, water can be distributed to multiple zones simultaneously.

[00101] A microfilter 982 is also disposed within the sprinkler head conduit 970 for a final filtration of water prior to discharge through the discharge nozzles 974. The microfilter 982 is able to last with only periodic maintenance as a result of the filtering and cleaning of water throughout the irrigation recirculation system. [00102] In the example of Fig. 9, a fire prevention subsystem 984 is provide that includes a dwelling conduit 986 that is fluidly connected and disposed within the distribution tank 950 to provide a fluid flow path from the distribution tank 950 to a dwelling 988. In this example the dwelling 988 is illustrated as a single family home; however, in other examples the dwelling 988 may include apartment buildings, office buildings, bams, sheds, or the like. Additionally, while the dwelling conduit 986 is illustrated at the top, or adjacent the ground level 908, in other examples, the dwelling conduit 986 is disposed within the distribution tank 950 at other locations, including adjacent the bottom of the distribution tank 950. Similarly, the dwelling conduit 988 may extend underground, parallel to the inlet fluid flow conduit 902, at an angle to the inlet fluid flow conduit 902, perpendicular to the inlet fluid flow conduit 902, or the like.

[00103] Disposed within the dwelling conduit 986 is a dwelling pump 990 that is operably controlled by the control system 968, and a dwelling valve element 992 similarly controlled by the control system 968. Either of the dwelling pump 990 or dwelling valve element 992 may be optional. The dwelling conduit 986 includes a main body 994 that may include the dwelling pump 990 and dwelling valve element 992 and a series of tributary sections 996A-C extending from the main body 994. Each tributary section 996A-C may have one or more dwelling discharge nozzles 998 positioned to discharge water conveyed from the distribution tank 950 onto the dwelling 988, including the roof, siding, doors, or the like. The dwelling discharge nozzles 998 may be positioned on the roof of the dwelling 988, in a yard of the dwelling 988 and positioned to discharge on the side of the dwelling 988, or the like. As a result, filtered water, free of debris, may be discharged onto the dwelling 988 from the dwelling discharge nozzles.

[00104] The fire prevention system 984 also includes one or more fire detectors 999. Each fire detector 999 may be a smoke detector, carbon monoxide detector, temperature sensor, or the like utilized to detect the presence of a fire. In an example, at least one fire detector is located exterior to the dwelling in order to detect the presence of fire from outside the dwelling. In one such example, the fire detector is located remote of the dwelling, including in one embodiment with the fire detector on a sprinkler head. In particular, these exterior fire detectors 999 are positioned to detect the presence of fire from external sources such as a wild fire that may be sweeping through a neighborhood.

[00105] Each fire detector 999 is in communication with the control system 968 to provide fire related signals to the control system. Then, in response to the signals the control system determines if a fire is present. In one example, the fire related signals are analyzed utilizing mathematical calculations, including in one example an algorithm to make the determination a fire is presented. In another example, the control system 968 compares a detected reading sent within the fire related signals and if above a threshold amount, a determination is made a fire is presented. In yet another example, a reading or readings from the fire related signal is utilized in association with a look-up table to determine the fire is presented. In yet another example, a threshold reading is exceeded for a predetermined amount of time to make the determination that the fire is present.

[00106] Once the control system 968 determines that a fire is present at or adjacent the dwelling, the control system may actuate the dwelling pump 990, dwelling valve element 992, sprinkler head pump 972, distribution valve element 976, or the like, in order to discharge water from the dwelling discharge nozzles 998 and/or sprinkler discharge nozzles 974 in order extinguish the detected fire and prepare the dwelling and surround area for the fire. Based on the determined location of the fire, the control system 968 may actuate only the dwelling pump 990 and/or dwelling valve element 992, only the sprinkler head pump 972 and/or distribution valve element 976, or may simultaneously actuate the dwelling pump 990, dwelling valve element 992, sprinkler head pump 972, and/or distribution valve element 976 in response to detecting the presence of the fire. In another example, the control system may send a notification signal to a remote device, such as a communication device at a fire station, a mobile device of a home owner, or the like, to notify the individual of the operation of the fire prevention subsystem 984 and potential fire at the dwelling 988.

[00107] Fig. 10 illustrates a method 1000 of extinguishing a fire with an irrigation recirculation and fire extinguishing system. In one example, the irrigation recirculation and fire extinguishing system is the system 900 of Fig. 9. At 1002, one or more processors detect presence of a fire at or adjacent a dwelling. In one example, at least one fire detector is utilized in association with the dwelling to detect the presence of the fire. The fire detector may be a smoke detector, carbon monoxide detector, temperature sensor, or the like utilized to detect the presence of a fire. The fire detector may be located exterior to and on the dwelling in order to detect the presence of fire from outside the dwelling, or interior of the dwelling. In another example, the fire detector is located remote of the dwelling, including in one embodiment with the fire detector on a sprinkler head. In particular, these exterior fire detectors, including fire detectors located on the dwelling and remote of the dwelling are positioned to detect the presence of fire from external sources such as a wild fire that may be sweeping through a neighborhood as described above.

[00108] At 1004, responsive to detecting the presence of the fire, the one or more processors actuate the irrigation recirculation and fire extinguishing system to discharge water onto the dwelling with dwelling discharge nozzles. In one example, the one or more processors actuate a dwelling pump and/or dwelling valve element to cause water to flow from an underground storage system, and in particular a distribution tank that includes filtered water, to the dwelling discharge nozzles. By filtering the water, reliability of delivery of the water to the nozzles or fire prevention purposes is provided. Additionally, the one or more processors may use methodologies as described herein, and as an example, the methodology described in relation to Fig. 8 to clean the dwelling discharge nozzles to ensure water may be utilized for fire extinguishing purposes. While the irrigation recirculation and fire extinguishing system of Fig. 9 illustrates only one dwelling valve element, in other examples, each tributary section of a dwelling conduit may include a dwelling valve element controlled by the one or more processors to selectively discharge water at predetermined locations of the dwelling to minimize potential water damage caused from actuation of the system.

[00109] At 1006, optionally, responsive to detecting the presence of fire, the one or more processors actuate the irrigation recirculation and fire extinguishing system to discharge water from one or more sprinkler discharge nozzles. In one example, the one or more processors actuate a distribution pump and/or distribution valve element to allow delivery of filtered water from a distribution tank to the sprinkler discharge nozzles. Similar to the dwelling discharge nozzles, the sprinkler discharge nozzles may be cleaned using methodologies described herein, including the methodology associated with Fig. 8. By keeping the water filters and the sprinkler discharge nozzles clean, the effectiveness of extinguishing a detected fire is increased. In one example at least one sprinkler discharge nozzle is positioned adjacent the dwelling to discharge water onto the dwelling. In one embodiment a valve element associated with each such sprinkler discharge nozzle is actuated to cause the discharge. In this manner, when a fire is not detected, the sprinkler discharge nozzle will not discharge onto the dwelling. In another embodiment, the sprinkler discharge nozzle is rotatable 360° degrees, and the one or more processors are operable to control the rotation of the sprinkler discharge nozzle to rotate to discharge water onto the dwelling when a fire is detected and to rotate to not discharge water onto the dwelling with a fire is not detected. Thus, the sprinkler discharge nozzles may supplement fire extinguishing of the dwelling discharge nozzles to additionally protect a dwelling and/or property through simultaneous or independent actuation of the dwelling pump, dwelling valve element, sprinkler head pump, and/or distribution valve element in response to detecting the presence of the fire.

[00110] At 1008, the one or more processors optionally transmit a notification to a remote device at a remote location in response to detecting the presence of the fire. In one example, the remote device is a communication system associated with emergency workers, such as a fire station, police station, or the like. In another example, the remote device is associated with an owner or personnel of the dwelling and may include a personal computing device, a mobile device including a mobile phone, iPad, iPod, or the like, a wearable device including a smart watch, physiological monitoring device, or the like, or the like. The notification may include auditory notifications including voice messages, beeps, other sounds or the like, visual notifications, including text messages, other written messages, flashing or intermittent light, different colored lighting, or the like, haptic or tactile notifications including vibrations, or the like. Each notifies an individual the fire detected and in the case of an emergency worker notification may include information related to the location or address of the dwelling, the location of the detected fire, reading from fire detectors resulting in the determination of the presence of a fire, or the like.

[00111] Provided is a system and method that includes an irrigation recirculation and fire extinguishing system and method of extinguishing fires using the same. The system utilizes filtered and stored water from the exterior of a dwelling and within the ground to supply filtered water to and adjacent the dwelling for fire prevention. The system is self-contained and automatic, resulting in the use of city water to be unnecessary. The filtering of the water ensure proper operation of the system. Thus, in areas where a wild fire is presented an emergency worker may not be able to assist in extinguishing the fire, the system detects the presence of the fire and utilizes the stored and filtered water to extinguish the fire and protect the dwelling and property.
