Rain Water Harvesting

Rainwater harvesting is the best method or technology used to conserve rainwater to support the conservation of water by capturing rainwater, storing it, conveying the harvested water and purifying the rainwater that runs off from rooftops, hill slopes, parks, roads, open grounds, etc. for later use.

Nowadays, scarcity of water has become a significant cause and problem in our life.  Thus, conserving rainwater, which is pure and of good quality water, can be used in many ways like plant irrigation, washing and cleaning things, bathing, cooking and other livestock requirements.

Rainwater harvesting systems consist of the following components:

  • Catchment– It is used to collect and store the captured rainwater.
  • Conveyance system – It is used to transport the collected water from the catchment to the recharge zone.
  • Flush- It is used to flush out the dirts from the first spell of rain.
  • Filter – Used for filtering the harvested rainwater and removing pollutants and dirts.
  • Tanks and recharge structures -Used to store the filtered water which is ready to use.

The Benefits of Rainwater Harvesting are listed below in points, 

  • Rainwater harvesting is a relatively simple technology, easy to install and operate and has less installation cost.
  • It helps in reducing the water demands mainly in cities and in urban areas.
  • Rainwater harvesting increases water availability during dry seasons by increasing the levels of dried borewells and wells.
  • Reduces the need for imported water and also cost for transport.
  • It helps in both water and energy conservation.
  • Rainwater harvesting does not require filtration system for landscape irrigation.
  • It improves the quality and quantity of groundwater.
  • Rainwater harvesting reduces soil erosion, stormwater runoff, flooding, and pollution of surface water with fertilizers, pesticides, metals and other sediments.
  • It is an excellent source of water for landscape irrigation and many households purpose as it has no chemicals, dissolved salts and free from all minerals.
  • Rainwater harvesting also helps in the availability of potable water, as rainwater is substantially free of salinity and other salts.
