Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs.
Roof top rainwater harvesting structures.
Here are some common components involved in these stages.
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.
Typical roof top harvesting structure under method a the down pipe is moved away from the inlet of the storage tank initially during the rains until clean water flows.
Rainwater harvesting pages are not under access control although rainwater harvesting has been implemented in all the urban local bodies it is now felt that there is a need to modify some of the structures.
Roof top rain water harvesting rrwh section.
Components of rooftop rainwater harvesting the process involves transporting rainwater through pipes and drains filtration and storage for reuse recharge.
Therefore the catchment is the area which actually contributes rainwater to the harvesting system.
The surface that receives rainfall directly is the catchment of rainwater harvesting system.
Our projects depend on a good monsoon.
It s in our name we harvest water.
We need the rains in order for the structures to work.
These are cleaned off after each heavy rain.
It may be terrace courtyard or paved or unpaved open ground.
78000 70 100 54600 or say 55000 thus the rainwater harvested from each house of 100 sq m.
Whilst the monsoons do come every year some areas can receive hardly any rain the rain water harvesting structures are full read more.
It s what we do.
Percent rainfall considered for harvesting is 70 of annual rainfall 550 mm 780 20 2000 78000.
Following a good monsoon our water harvesting structures are now full.
Rainfall 20 mm in single event.
The main objective of rooftop rain water harvesting is to make water available for future use.
Of roof area 55 cum can meet the.
Total annual rainfall about 780 mm.
Under method b storage provision for initial rain is kept in a pipe.
