Rainwater Harvesting

Advantages of Rainwater harvesting system in your home:

We all know that ever-increasing human population cannot only depend on ground water, and due to this, rivers and lakes are being exploited. This not only pollutes them, but destroys its internal network. By saving rainwater, we are reducing the dependence on rivers, lakes and underwater bore wells. Several state governments in the country have made it mandatory for new buildings to have rainwater harvesting tanks. Saving rainwater does save the planet!

What is rainwater harvesting?

Rainwater harvesting is artificial way to collect and store the rainwater and use it when needed. Mostly water is collected from hard surfaces like rooftop and other raised solid surfaces. Simple infrastructural changes can be done for rainwater harvesting. Sometime rainwater is stored in manmade pits and used for onsite water supply or to recharge ground water.

It is easy to set up and inexpensive:

You don’t have to dig deep in the ground or your wallet to set up a rainwater harvesting tank. Building these catchments is a cheap alternative when compared to building a well or setting up a bore well. It also takes a shorter time to install. Rainwater harvesting can be as simple as storing water in your usual water tank. However, optimal rainwater harvesting for your home requires a catchment tank and a percolation pit. It can be set up within a day without any hassle. These days, builders are required to provide rainwater harvesting systems in the houses they build.

Purified rainwater is cheap and safe for drinking:

 Rainwater is one of the freshest sources of water as it is untouched by impurities in the ground. Rain water harvesting is sustainable way of water conservation. Such water can be used throughout the year for all basic needs after filtration and UV disinfection. After this purification, it can be used for drinking and cooking. Rainwater harvesting tanks are an advantage in big cities like Bangalore, where most residents rely on water cans, kaveri/municipal water or expensive water purifiers etc. So by using rainwater, your dependence on municipal water is reduced, thereby reducing your water bill. Rainwater tanks provide a ready supply of water, allowing you to depend less on municipal water and making your home self-sufficient. It is also a cleaner source of water.

 Rainwater is good for gardening:

 Rainwater is not only beneficial to us; we can use it is to plants, as well. It nourishes them better than any other water source. It does not contain much chemicals compare to municipal water and it makes your garden greener, quite literally!

It improves the quality of soil and groundwater:

Rainwater is to help to increase and purifies the groundwater and the soil by washing off chemicals and energizing the water and soil’s quality.

Prevents the overflowing of drains and sewers:

When we think about the rainy season in all the big cities in India, images of overflowing drainage are likely to come up in our minds. By collecting rainwater, harvesting tanks prevent the excessive clogging of roadside drains and sewers, making both your home and your city little bit cleaner. It also prevents the soil erosion.

It conserves energy:

Since most people in cities depend on groundwater and municipal water, a lot of energy is consumed while obtaining it. The pumping and filtering of groundwater consumes a large amount of electricity, and as a result, which raises your electricity bill. Rainwater harvesting provides a ready supply of water without the need for pumping and it requires a minimal amount of filtering.

Rainwater Harvesting System

Finally we can summarize the advantages of rainwater harvesting as below:

  • It provides water supply other than Monsoon season. Provides free water supply and reduces water bills.
  • It is very helpful in drought condition.
  • A step towards sustainable water supply.
  • Reduces flooding, erosion and storm drain overflow.
  • Reduces the energy used in water supply thus reducing your Carbon Footprint.
  • Reduces environmental damage to rivers and lakes due to flooding.
  • Can be used to recharge groundwater.
  • Useful for Garden plants.
  • Good for laundry and reduces the amount of detergent required.
  • Is beneficial to washing machines as it does not produce lime scale.
  • Promotes self-sufficiency.
  • Simple to install and easy to maintain.
  • Gains Eco-home points for the property.
