Run off rainwater harvesting
Practical Action
Figure 5: Wall construction of the tank on the concrete base
As the water inlet is connected to the tank at the ground level, hence, the water inlet
wall should not be raised above the surface level.
Figure 6: Measurement taken for the inlet construction
The mud filters are attached to the water inlet. Hence the door has to be sturdy. As
depicted in the picture below, a concrete slab measuring in metres 0.75m X 1m
(height and length) should be laid near the door.
Figure 7: Concrete base for the inlet construction
When constructing the water inlet, it is necessary to face it in the direction of the
natural water-flow of the garden. As the mud filters should be placed around this door,
a drain should be constructed close to the inlet of 0.5 meters (near the door) and 1
metre width. The total length of this drain should be 1 metre.
