Rain Water Harvesting- What – How – Cost?

Rainwater harvesting is the direct collection of rainwater to supplement some of our water needs.

Why rainwater harvesting?

Broadly rainwater can be harvested for two purposes Storing rainwater for ready use in containers above or below ground Charged into the soil for withdrawal later (groundwater recharging)

Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock, water for irrigation, and indoor heating for houses etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation.

Rainwater can be:

  Stored for direct use or to recharge the groundwater levels

  Channelized through a filter bed into an underground storage tank

  Used for flushing, washing utensils & clothes and even gardening

A 20,000 litres tank requires a one - time cost of less than Rs. 2,000 per flat and needs very little maintenance.
