Design of Rainwater Harvesting System

The gap between water demand and supply has been continuously widening. This has led to increase emphasis on the optimal management of the available water resources. Rigorous planning and management of water resources is required for long term sustainable resource development. Hence rainwater harvesting is the engineering solution to water problem of urban area especially in semi-arid region. In order to apply concept of rain water harvesting, the MVGR college campus is taken as study area to plan analyze and design rainwater harvesting system to reduce the impact on ground water as the only source of water is ground water on which the people are depending for various needs. Detailed survey had been carried out in our campus regarding on water consumption, existing RWHS and proposed new systems. Placing of non bio degradable plastic filters between each layer in recharge pits, which helps for prevention of entering sand particles into pores. By adopting these methods we can save more money on water consumption and maintenance cost.
