Rapid urbanisation and developmental pressure are plagued with uncertainties in the future. This will impair any urban water management strategies that are insensitive to these factors. Hence, there is a need to develop processes that are robust, adaptable and sustainable to the future pressures. This calls for a paradigm shift in managing urban and peri urban water bodies. One of the solutions to the urban water crisis is through rainwater harvesting - capturing the runoff.


The salient features of Rain Water Harvesting:

  • Simple straight-forward installation
  • Easy to operate and maintain
  • Needs no power and operates at low gravity pressure

Rain water harvesting is collection and storage of rain water that runs off from roof tops, parks, roads, open grounds, etc. This runoff can be either stored or recharged into the ground water. Under the existing project it is proposed to channelize the rain water from roof tops and other areas into the lake. A rainwater harvesting system to revive the urban lakes consists of the following components:
