Rainwater harvesting is the collection and storage of rainwater for reuse rather than letting it run off.
It conserves water, recharges groundwater and reduces dependence on municipal supply.
Surface runoff harvesting collects water in tanks or reservoirs, while rooftop harvesting channels roof water through gutters and filters into storage or recharge pits. Recharge methods replenish groundwater through wells, trenches and percolation pits.
A typical system includes a catchment, conveyance, first-flush diverter, filter and storage or recharge structure.
