Note on the Filter:
For water to be sufficiently filtered through gravel, sand and clay, a sufficient pressure is required, in the range of 1 bar, gage pressure.
For this to be achieved by gravity, the filter has to lie at a given depth under the manifold.
Gage Pressure = Density x acceleration gravity x Depth
!00,000 = 1000 x 9.81 x Depth
Depth = 10.19 meters
