Water Emergency Control
Precautions against the effects of often recurring floods need to be taken at a collective as well as at household level. Such measures should be within the reach of the local community, where governmental care is not to be expected.
The ideas, here presented give a general idea how they can be realized: a raised food storage, an emergency raft, safe access to water at one's yard and a raised pump platform.
- Existing open well or tube well, later to be modified
- Concrete rings, a brick ring, or a pipe extension.
- Compacted clay shapes a ring that must prevent dirty water from seeping in during a flood.
- Small rectangular platform accommodates only coming and going users. Three sides are steep enough to moor small boats or to come close enough with a truck.
- Steps in the access side prevents slipping in rainy or undulated conditions.
- People, waiting for their turn can stand in line, without hindering a person who takes the collected water home.

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.
