Rainwater Harvesting- Interesting Solutions To Water Crisis

Strategies To Manage Rain Water

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


Individual homes






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.

Researchers For Spreading Awareness On Rain Water Harvesting:


an Indian startup company that aims to manufacture sustainably engineered products that intelligently conserve water, energy, and waste, has raised angel funding to expand operations, and begin sales and distribution activities.

The company?s first product, called Ulta Chaata, is an inverted canopy looking structure that provides potable water by capturing rainwater during the monsoon season and solar energy during the rest of the year. Each unit has the capability to harvest and filter up to 100,000 liters during the rainy season.

With a maximum solar capacity of 1.5KW the Ulta Chaata also includes an intelligent lighting system that provides various levels of programmable lighting options and a mobile charge unit, thereby making it a completely self-sustaining installation for the outdoors.

MBA Students Quit Their Job To Work On Rain Water Harvesting

Three MBA friends got stuck in a relentless shower of rain in Gurugram. Ankit Magan, Priyank Jain, and Neeraj Chauhan were there for some work and had to wait more than 45 minutes for the rain to stop. Because of the rain, the roads were waterlogged and the drainage systems were choked up.

As the friends contemplated this, they decided they must do something to preserve rainwater. Despite having full-time jobs, they wanted to start their own rainwater preservation business and become ?waterepreneurs.?

Conservation helps, because, it does not impact the way we live, says Vivek Shukla, founder of SmarterHomes Technologies. The organization provides smart water metering solutions to housing societies.

The three-year-old company currently has its presence across Bengaluru and Hyderabad. It has installed over 4500 water meters across small-medium apartment complexes and individual houses.
