How is rain water harvested in India now?
Surface runoff harvesting is the most suitable method in urban clusters. Here, streams of surface runoff rainwater are redirected and stored for future use in specially-built reservoirs, either on the surface or underground. This provides a steady supply of clean, potable water, and also water for normal domestic uses.
What is the importance of rainwater harvesting in India?
The materials used do not require complicated frequent maintenance. Hence this whole process is cost-effective. Prevention of soil erosion and floods is one of the most important reasons why we should adopt rainwater harvesting. It saves millions of gallons of water from going down the drains.
Who introduced rainwater harvesting?
Rainwater harvesting was also common in the Roman Empire. While Roman aqueducts are well-known, Roman cisterns were also commonly used and their construction expanded with the Empire. For example, in Pompeii, rooftop water storage was common before the construction of the aqueduct in the 1st century BC.

How important is rainwater harvesting?
The importance of rainwater harvesting lies in the fact that it can be stored for future use. Just as it can be used directly so also the stored water can be utilized to revitalize the ground level water and improve its quality. Harvesting rainwater checks surface run off of water and reduces soil erosion.
What are the benefits of rainwater harvesting?
The advantages of rainwater harvesting are:
- It is cost-effective.
- Conserves water.
- A source of water for landscape irrigation.
- It is a simple method and easy to practice.
- It reduces soil erosion and pollution of water bodies due to fertilizers and pesticides.
What is the importance of rainwater harvesting?
It reduces soil erosion and flood hazards by collecting rainwater and reducing the flow of stormwater to prevent urban flooding. Most buildings that utilize rainwater harvesting systems have a built-in catchment area on top of the roof, which has a capacity of collecting large volumes of water in case of rainstorms.

RWH in urban areas also consists in reviving whatever water bodies that are left behind without allowing any further construction in them in future.
