Roof Top Rainwater Harvesting Structure

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 structure.

The process involves transporting rainwater through pipes and drains filtration and storage for reuse recharge. Its uses include watering gardens livestock irrigat. Rainwater harvesting differs from stormwater harvesting as the runoff is collected from roofs rather than creeks drains roads or any other land surfaces. Therefore the catchment is the area which actually contributes rainwater to the harvesting system.

It may be terrace courtyard or paved or unpaved open ground. 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. The main objective of rooftop rain water harvesting is to make water available for future use. Under method b storage provision for initial rain is kept in a pipe.

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. It can either be stored in a tank or diverted to a man made recharge system. Here are some common components involved in these stages. Rainwater harvesting is the collection and storage of rain rather than allowing it to run off.

Rainwater is collected from a roof like surface and redirected to a tank cistern deep pit aquifer or a reservoir with percolation. Dew and fog can also be collected with nets or other tools. In roof harvesting the roof turns into a catchment and rainwater is collected from the roof of the house building. The surface that receives rainfall directly is the catchment of rainwater harvesting system.

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. Surface which directly receives the rainfall and provides water to the system. It may be a terrace courtyard or paved or unpaved open ground.

Rooftop rain water harvesting structure is a unique system this system will be allowed to enter into filter media of water harvesting structure. These are cleaned off after each heavy rain. These are provided between. The terrace may be flat rcc stone roof or sloping roof.

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. It can be a paved area such as a building terrace or courtyard or an unpaved area such as a lawn or an open ground. Components of rooftop rainwater harvesting.
