To provide a water cleaning system in which turbid water can be cleaned to the extent that the cleaned water is drinkable, which can be downsized and the power consumption of which is made small.
The water cleaning system is provided with: a unit (5) for charging a flocculant to turbid water and agitating them; a first filtration unit (7) which is arranged on the downstream side of the unit (5) and used for filtering the flocculated foreign matter (slag); a plurality of filtration units (8, 11) arranged on the downstream side of the first filtration unit (7); and a controller (40). The first filtration unit (7) has a filter (73) and a pressure measuring unit (23) for measuring the pressure in the upstream-side area of the filter in the first filtration unit (7). The controller (40) has a function of reporting that the filter (73) of the first filtration unit (7) has to be exchanged when the pressure measured by the pressure measuring unit (23) exceeds a threshold value.
