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.
Roof top rainwater harvesting ppt.
Roof top rain water harvesting system.
Removes rooftop debris protects tank water quality install above or below ground filter capacity up to 33 000 ft2 1.
Components of the roof top rainwater harvesting system.
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.
Water requirement is met by one bore well and is supplemented by municipal supply.
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.
Rainwater harvesting seminar and ppt with pdf report.
This technique is particularly useful in dryland hilly urban and coastal areas.
Pre tank filtration after m ore than 20 years in the rainwater industry rainwater managem ent solutions has identified the w isy 4 step system as the ideal m ethod for rainwater harvesting.
The main objective of rooftop rain water harvesting is to make water available for future use.
Rainwater harvesting systems installed in multistoried buildings can suffice for daily water usage by the building residents.
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.
Well recharging method 2.
Roof top rain water harvesting system rooftop rainwater recharging y following are the methods of recharging ground.
In rooftop harvesting the roof becomes the catchments and the rainwater is collected from the roof of the house building.
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.
Total volume of rainwater harvested 4446 metre cubic.
Roof top rain water is collected in collection chambers and diverted to recharge wells through interconnecting pipe lines.

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.
Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs.
This method is less expensive and very effective.
Total roof top surface area 13910 sq.
It consists of conservation of roof top rain water in urban areas and utilizing it to augment ground water storage by artificial recharge.
