Rainwater Harvesting And Utilisation. An Environmentally Sound Approach for Sustainable Urban Water Management: An Introductory Guide for Decision-Makers. In most urban areas, population is increasing rapidly and the issue of supplying adequate water to meet societal needs and to ensure 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 water.

Rain Water Harvesting Rainwater Harvesting Rainwater harvesting in broad sense can be defined as the collection of runoff for human consumption. Rainwater or fog harvesting collects water directly where it falls as rain or snow, from ground surfaces or rooftops or by intercepting fog. Rooftop rainwater and intercepted fog are commonly of a good quality, but may be affected by air pollution, dirt on roofs or rust on metal sheets. Rain Water Harvesting (URWH), among others, 11 Rainwater Harvesting & ChRft Stt Roof Catchment .Roof Top Rainwater Harvesting Rooftop Rain Water Harvesting - technique through which rain water is captured from roof catchments. Roof-based rainwater harvesting refers to collecting rainwater runoff from roof surfaces which usually provides a much cleaner source of water Harvested rainwater is also used in many parts of the world as a drinking water source. As rainwater is very soft there is also less consumption of Rainwater harvesting technologies for agricultural production: A File Format: PDF/Adobe Acrobat.

Rainwater harvesting is a mini-scale water resources project that collect stores rainwater by structural measures and regulates and make us use of it for domestic and production use.

This article demonstrates the combination of satellite image analysis and modelling as tools for the development of an urban rainwater harvesting policy. Rainwater harvesting is an important environment friendly approach - dubbed as a Green Practice which has double benefit in both keeping the groundwater table undisturbed and charging the aquifer. Such a green practice encouraged in form of Community Development Program can find its popularity
