The main objective of rooftop rain water harvesting is to make water available for future use.
Roof top rainwater harvesting structure.
The process involves transporting rainwater through pipes and drains filtration and storage for reuse recharge.
It can either be stored in a tank or diverted to a man made recharge system.
Dew and fog can also be collected with nets or other tools.
It may be terrace courtyard or paved or unpaved open ground.
Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs.
The terrace may be a flat rcc stone roof or sloping roof.
This technique is cheap very efficient and if applied properly helps in growing the groundwater level of the area.
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.
These are provided between.
Removes rooftop debris protects tank water quality install above or below ground filter capacity up to 33 000 ft2 1.
Under method b storage provision for initial rain is kept in a pipe.
Rainwater harvesting differs from stormwater harvesting as the runoff is collected from roofs rather than creeks drains roads or any other land surfaces.
It may be a terrace courtyard or paved or unpaved open ground.
Here are some common components involved in these stages.
Rainwater is collected from a roof like surface and redirected to a tank cistern deep pit aquifer or a reservoir with percolation.
These are cleaned off after each heavy rain.
Components of rooftop rainwater harvesting.
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.
Therefore the catchment is the area which actually contributes rainwater to the harvesting system.
Its uses include watering gardens livestock irrigat.
Rooftop rain water harvesting structure is a unique system this system will be allowed to enter into filter media of water harvesting structure.
Surface which directly receives the rainfall and provides water to the system.
The terrace may be flat rcc stone roof or sloping roof.
In roof harvesting the roof turns into a catchment and rainwater is collected from the roof of the house building.
Rainwater harvesting is the collection and storage of rain rather than allowing it to run off.
The surface that receives rainfall directly is the catchment of rainwater harvesting system.
Therefore the catchment is the area which actually contributes rainwater to the harvesting system.
