Study Of Diversion And
Delivery In Rain Water Cisterns In India
Christian Industrial Training Association Madras, India
In some hilly areas in North West India, seasonal rainfall, being only source
of drinking water, is collected in Household Jars and Cisterns of Brick, Masonry
and Corrugated Tin. Presently concrete and Ferro-cement Cisterns are also built
for adequate storage to meet family needs throughout the year. Rain water collected
in Metal or Tile Roofs is conveyed through Gutter and Downpipe directly to the
Cistern below. But nowadays because of increased road traffic, there is much settlement
of dust on the roofs s in dry months. Roof Wash Filter and Diversion on for Foul
Flush is introduced. Flexible pipes or Flap Valve and inverted 'Y' Pipe arrangements
are used. System, however, is not very, effective as people neglect to manually
change position after rains. The objective of this paper is to of offer a simple
but Automatic Diversion System using a leaking Bucket and Counterweight principle.
Water delivery from Cisterns above ground is by gravity flow.
Hand pumps are used for cisterns below ground, for which a more effective foot
pedal pump is being tried out. For larger applications for community use, a simple,
low cost single mast windmill, held in position by guy ropes, has been developed
using components such as Bicycle and Hand Pump parts which are all easily available
in the local market. Specifications, technical details and photographs presented.
The paper also recommends suitable measures for promoting rainwater harvesting
techniques in drought prone areas in India. and other developing countries.
