Title:
VACUUM SEWAGE SYSTEM WITH SUMP BREATHER APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/190310
Kind Code:
A8
Abstract:
A vacuum sewage system includes a sump pit (12) for receiving sewage, a valve pit (26), a valve (30), a sensor-controller (66), a first sensor pipe (37), a sump breather (400) and a second sensor pipe (300). The sensor-controller activates the valve so as to discharge sewage from the sump pit. The first sensor pipe communicates pressure to the sensor-controller as the level of sewage rises within the sump pit. The second sensor pipe communicates pressure to the sump breather to move the sump breather from a first state to a second state to prevent sewage from entering the sensor-controller and valve.
