I used eight because I wanted to have an ample supply of water to use during drought periods, and 440 gallons seemed about right to me. Plantings can be placed to cool buildings in summer. The use of flat sheets of galvanized iron with timber frames to prevent corrosion was recommended and constructed in the State of Victoria, Australia, about 65 years ago (Kenyon, 1929; cited in UNEP, 1982). Roof catchments should also be cleaned regularly to remove dust, leaves and bird droppings so as to maintain the quality of the product water (see figure 1). Additionally, the app provides images and directions detailing how to construct rainwater harvesting systems with locally available materials. Cisterns for storing rainwater have been found in communities as far back as Neolithic times, and by 2500 BC they could be found in what is now Israel and the Greek island of Crete, and later in the Roman Empire, Istanbul, and even Venice.

Collecting rainwater can also reduce erosion in especially very dry environments where it is common, and reduce flooding in low-lying areas. Influencing factors for Rainwater Harvesting Quantity of Rainfall Precipitation is the foremost unusual and unpredictable variable and thus, to decide the potential water supply for a given catchment, solid precipitation information is required, ideally for a period of at least 10 years. He is also a retreat consultant specializing in off-grid living, rural relocation, and survival preparedness. You will also want to ensure that the water isn’t coming into contact with lead, heavy metals, or preservative-treated timber on your roof, if that serves as your catchment area.

All content following this page was uploaded by Rohit Goyal on 25 October 2015. Rainwater harvesting (RWH) is increasingly becoming an integral part of the sustainable water. Use of plastic sheets, asphalt or tiles along with slope can further increase efficiency by reducing both evaporative losses and soil erosion. With this flap it is possible to direct the first flush of water flow through the down-pipe, while later rainfall is diverted into a storage tank. They can capitalize on increased technological infrastructure to expand its user base.
