Rain Water Harvesting System(Rwhs)

Rain Water Harvesting System (RWHS) is a process of collecting & storing the rainwater for later use. This system involves collecting rainwater from rooftops, hill slopes, or other surfaces, then filtering and storing it in underground reservoirs or tanks for various purposes like irrigation, domestic use, etc.
On the other hand, we can say, RWH is a cost-effective & eco-friendly method to preserve water resources. Although it assists to prevent water shortages throughout droughts.
Benefits of Rain Water Harvesting System:
Water Conservation: It helps in reducing the demand for surface water & groundwater. Also, beneficial in areas facing water shortages.
Environmental Benefits: This system reduces soil erosion and improves the water quality in rivers, lakes, and other water bodies by reducing the stormwater runoff.
Cost Savings: By using rainwater, you can decrease your water bill & save money on your water expenses.
Health Benefits: Well, using rainwater for domestic purposes can assist to reduce exposure to harmful chemicals & contaminants that might be present in water supply.
Irrigation: The RWH system can be even used for the irrigation purposes that can be advantageous for farmers & other agricultural users.
Well, below we have listed some of the components of rooftop rainwater harvesting:
First flush
Catchment
Transportation
Filter
Technique #2-Surface run off harvesting
The Surface runoff harvesting system is a process of collecting rainwater that flows away as a surface runoff. Although the runoff rainwater is caught & used to recharge aquifers via adopting suitable techniques.
Factors Affecting the Amount of Harvested Rainwater:
Catchment features
The capacity of storage tanks
Quantum of the runoff.
