Answer 1

Explanation:

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilized in different ways or directly used for recharge purposes. With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones.

What is RWH?

Rainwater harvesting is collection and storage of rainwater that runs off from rooftops, parks, roads, open grounds, etc. This water runoff can be either stored or recharged into the groundwater. Rainwater harvesting systems consists of the following components:

The catchment from where water is captured and stored or recharged, conveyance system that carries the water harvested from the catchment to the storage/recharge zone,

first, flush that is used to flush out the first spell of rain, filter used to remove pollutants,

storage tanks and/or various recharge structures.

Why Do We Need To Harvest RainWater?

Rain may soon be the only source of clean water. Rainwater harvesting systems use the principle of conserving rainwater where it falls and has the following benefits:

Helps meet the ever-increasing demand for water

Improves the quality and quantity of groundwater

Reduces flooding

Where?

Individual homes

Colonies

Apartments

Institutions

Schools/colleges/universities

Hospitals

How Does It Happen?

Setting up a rainwater harvesting is not difficult but requires some sort of understanding of hydrology and architecture and as a result, most people find it too complicated to do it themselves. In order to make it simple and convenient for everyone to set up a rainwater harvesting system suitable for their needs, we have prepared a set of guidelines which will help you to set up your own rainwater harvesting system quickly and efficiently.
