Rainwater or surface run-off from rooftops, courtyards, or artificially prepared catchments (locally called agor) flow into the tank through filtered inlets in the wall of the pit. [ 2 ] [ 3 ] The water stored saves people from the daily task of walking long distances to fetch water from sources which are often contaminated.
configuration of domestic rainwater harvesting system in Uganda. [1]Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off.. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground w
A rainwater catchment or collection (also known as "rainwater harvesting") system can yield 1,000 litres (260 US gal) of water from 1 cm (0.4 in) of rain on a 100 m 2 (1,100 sq ft) roof. Rainwater tanks are installed to make use of rain water for later use, reduce mains water use for economic or environmental reasons, and aid self-sufficiency .
Gutters prevent water ingress into the fabric of the building by channelling the rainwater away from the exterior of the walls and their foundations. [9] Water running down the walls causes dampness in the affected rooms and provides a favourable environment for growth of mould, and wet rot in timber. [citation needed] A rain gutter may be a:
The city's firefighting network, the Auxiliary Water Supply System (AWSS) maintains a network of 177 independent underground water cisterns, with sizes varying from 75,000 US gallons (280,000 L) to over 200,000 US gallons (760,000 L) depending on location with a total storage capacity of over 11 million U.S. gallons (42 million liters) of water ...

Aug. 1—Marc Bedner shakes his head in disbelief while standing by his two rain-catching cisterns placed at an outside corner of his home in Eldorado. He glances at the brown tanks, both ...
Rainwater is almost always collected strictly from the roof, then heavily filtered using either a filter attached to the down pipe, a fine basket filter or for more expensive systems like self-cleaning filters placed in an underground tank. [2] UK homes using some form of rainwater harvesting system can reduce their mains water usage by 50% or ...
