RAIN WATER HARVESTING (RWH)

Rain Water Harvesting process of collecting, storing, and using rainwater for various purposes such as irrigation, domestic use, and groundwater recharge. This method involves capturing rainwater from rooftops, land surfaces, or other catchment areas, channeling it through gutters and downspouts, filtering out debris, and storing it in tanks or cisterns for future use. Rainwater harvesting helps conserve water, reduce dependence on municipal water supplies, manage stormwater runoff, and promote sustainable water management practices.

RAIN WATER HARVESTING - PROCESS & PURPOSE

S.NO.	COMPONENTS	PURPOSE	PROCESS
1	Catchment Area:	To collect rainwater.	Roofs, terraces, or other surfaces serve as the primary catchment areas where rainwater is collected.
2	Gutters and Downspouts:	To channel collected rainwater from the catchment area to storage.	Rainwater flows from the catchment area into gutters and downspouts, which direct it toward the storage system.
3	First Flush Diverter:	To remove the initial runoff, which may contain contaminants.	The first flush diverter captures the initial flow of rainwater, which is typically more polluted, and diverts it away from the storage system.
4	Leaf Screens and Filters:	To remove debris and particulate matter from the collected rainwater.	Screens and filters placed at various points in the system trap leaves, twigs, and other debris, preventing them from entering the storage tank.
5	Storage Tanks or Cisterns:	To store the collected rainwater for later use.	Rainwater is stored in tanks or cisterns, which can be made of plastic, concrete, metal, or other materials. These tanks are often equipped with lids to prevent contamination and evaporation.
6	Pump and Distribution System:	To deliver stored rainwater to its points of use.	A pump may be used to distribute water from the storage tank to various outlets, such as irrigation systems, toilets, washing machines, or even for potable use after appropriate treatment.
7	Treatment System (if needed):	To ensure water quality for specific uses.	Depending on the intended use, rainwater may require treatment. This can include filtration, chlorination, UV treatment, or other purification methods to ensure the water is safe for drinking or other sensitive applications.
