Roof top rain water harvesting system rooftop rainwater recharging y following are the methods of recharging ground. Roof top rain water harvesting or domestic rainwater harvesting is the technique through which rain water is captured from roof components and stored in tanks reservoirs ground water aquifers. Our earth is covered with 75 of water and 25 of land but water scarcity is a global issue because the large extent of water is not used for the domestic purpose irrigation purpose and one of the solutions for such problem is the rainwater harvesting. In the areas of regular rainfall the perfect alternative to overcome the water.

Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs. Rainwater harvesting systems installed in multistoried buildings can suffice for daily water usage by the building residents. Total volume of rainwater harvested 4446 metre cubic. In rooftop harvesting the roof becomes the catchments and the rainwater is collected from the roof of the house building.

Average annual rainfall in mm 792 4. Roof top rain water harvesting system. Borewell recharging method other minor methods are y farm pit method y farm trench method costs and economic viability of roof water harvesting system y two types of systems. Harvested rain water can be stored in subsurface ground water reservoir by adopting artificial recharge techniques to meet the household needs through storage in tanks.

It consists of conservation of roof top rain water in urban areas and utilizing it to augment ground water storage by artificial recharge. Roof top rain water is collected in collection chambers and diverted to recharge wells through interconnecting pipe lines. 1 catchment area 2 transportation 3 first flush 4 storage system 5 delivery system 6 filtration system 8. Total roof top surface area 13910 sq.

Powerpoint presentation created date. Rainwater collected in the roof flows down the pipes running down the length of building into service wells or percolation pits water trickles down the layer of pebbles and boulders designed for underground filtration filtered water flows into either recharge well or the collection chambers with this setup the building can draw water readily from its water table in. In rooftop harvesting the roof becomes the catchments and the rainwater iscollected from the roof of the house building. Removes rooftop debris protects tank water quality install above or below ground filter capacity up to 33 000 ft2 1.

Water requirement is met by one bore well and is supplemented by municipal supply. This method is less expensive and very effective. Rainwater harvesting seminar and ppt with pdf report. Components of the roof top rainwater harvesting system.

It can eitherbe stored in a tank or diverted to artificial recharge system this method is less expensive and very effective and ifimplemented properly helps in augmenting the groundwater level of the area 9.
