Dirt excavated from a 1.5 meter deep and 2 meter wide hole
Sheet plastic tube, 0,6 m diameter and 1 m height is placed in the hole, suspended from two sticks (3)
Shallow hole is filled with the clean sand (5), in a way that the sand is added evenly inside and outside the sheet plastic tube
Water enters when the area is flooded through the sand fill. It forms a reservoir in the plastic enclosure
Concrete slab makes a infiltration free connection with the sheet plastic tube
A standpipe is cast into the slab. Safe water can be collected in a suitable way from the reservoir, Through the standpipe the reservoir can be chlorided if needed.
