ABSTRACT:
Water is crucial and it has always been considered throughout history as a natural resource for the survival of humanity and other living beings therefore globally the shortage of quality water and its availability is an important issue. Groundwater is the only source of water of the Swami Vivekananda Airport Raipur, and it faces water crisis when the groundwater level decreases. In this scenario, Rain Water Harvesting (RWH) can contribute considerably to tackle these problems. Rainwater treatment systems can be installed at different potential locations in study area based on their physical site conditions such as slope, elevation etc. The airport has 38955.62 Square meters rooftop area out of 2.108 Square Kilometres total area, water collected from the rooftop will fulfil approximately 30% of the total daily demand of the airport. Apart from this airport is properly designed drainage system storm water is collected and separated into three potential zones. Zone I, II and III having area 0.2393, 0.4307 and 1.4382 sq. Kms respectively, which produce a different runoff amount based on maximum daily rainfall. Storm water is treated by Slow Sand Filter (SSF) of rate of 200 litres per hour per square meter and stored under design capacity, size and number of treatment unit depend on the maximum discharge at their respective zones. Treated rainwater is utilized for recharge purpose through the recharge trench when excess water comes from the rainwater tank. The cost-benefit analysis also done for before and after implementation of the project.
