Tapping Water Condensate from Ceiling Mounted Air Conditioners for Ground Water Recharge
Keywords:Ground water recharge, water conservation
Present work is a case study of rainwater harvesting needs and the measures being adopted for
northern part of Punjab, India, with special reference to district Amritsar. Block wise assessment of
groundwater reveals that all the 8 blocks of district Amritsar fall under over exploited category.
Long term water level fluctuation (May 2002-May 2012) shows a decline of 0.27 m to 0.74 m in
whole of the district. The Ground Water Information Booklet, Amritsar District, Punjab recommends
that rainwater harvesting and artificial recharge to ground water should be adopted to check
further decline in ground water, since natural recharge to aquifer system is not adequate to support
heavy withdrawal of ground water.
A subject area has been identified which is small and relatively overlooked but has notable
potential to tap the water for ground water recharge. 24 ceiling mounted AC's installed in HN
Chandrawat PG Block of Amritsar College of Engineering and Technology release water equivalent
to drinking water demand of 120 adults for a period of 100 days or around 33 adults throughout the
year. The water collection system and recharge structure has been suggested by the author. It also
eradicates the existing method of water disposal which is very tedious and highly inefficient
