Harvesting Rainwater

84 pages pdf format

Rainwater harvesting is a simple low-cost technique that requires
minimum specific expertise or knowledge and offers many benefits.
Collected rainwater can supplement other water sources when they
become scarce or are of low quality like brackish groundwater or polluted
surface water in the rainy season. It also provides a good alternative
and replacement in times of drought or when the water table drops
and wells go dry. One should, however, realise that rainfall itself cannot
be managed. Particularly in arid or semi-arid areas, the prevailing
climatic conditions make it of crucial importance to use the limited
amount of rainfall as efficiently as possible. The collected rainwater is
a valuable supplement that would otherwise be lost by surface run-off
or evaporation.
