Rain Water Harvesting Project

Rainwater harvesting is the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off. System of collection rainwater and conserving for future needs has traditionally been practiced in India. The traditional systems were time-tested wisdom of not only appropriate technology of Rainwater Harvesting but also water management systems, where conservation of water was the prime concern. Thus, the revival of water harvesting process needs to be necessarily be backed by people's initiative and active public participation. Generally people depend on government system, which has resulted in disruption of community participation in water management and collapse of traditional water harvesting system. Therefore, seeing the present scenario Dps, Bokaro has taken an initiative for the management and distribution of rain water through rainwater harvesting.

Why harvest rainwater ?
There are many reasons but following are some of the important ones.
  • To arrest ground water decline and augment ground water table
  • To beneficiate water quality in aquifers
  • To conserve surface water runoff during monsoon
  • To reduce soil erosion
  • To inculcate a culture of water conservation

How to harvest rainwater:
Broadly there are two ways of harvesting rainwater:

(i) Surface runoff harvesting: In urban area rainwater flows away as surface runoff. This runoff could be caught and used for recharging aquifers by adopting appropriate methods.
(ii) Roof top rainwater harvesting: It is a system of catching rainwater where it falls. In rooftop harvesting, the roof becomes the catchments, and the rainwater is collected from the roof of the house/building. It can either be stored in a tank or diverted to artificial recharge system. This method is less expensive and very effective and if implemented properly helps in augmenting the ground water level of the area.
DPS Bokaro has initiated roof top rain water harvesting project in its campus to consume rainwater for future use.
What are the uses?
  • Filtered water can recharge our groundwater source for human use
  • Watering plants in garden
  • Cleaning of the washroom and floor
  • Washing utencils
  • Water supply to the washrooms and swimming pool
  • Irrigation and crop cultivation
  • Refilling the fish ponds and fountains
  • Washing vehicles such as school bus.
