AN INTEGRATED DESIGN FOR ENSURING WATER SECURITY AT DEVASTHAL, INDIA
Devasthal site of Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital in central Himalayas is well known for its geographical location and accommodates three telescopes with their associated infrastructure. Further, development of site is planned with various upcoming astronomical and atmospheric instruments in near future. An integrated design for ensuring water security at this fast emerging astronomical observatory is carried out to supplement its existing sole ground water resource. Devasthal site receives sufficient rainfall but most of the water runs off and goes unutilized due to steep slopes and absence of natural barriers. Rainwater harvesting is seen as the most viable and long term solution to meet water requirements at remote site due to lack of conventional water supply systems. A scheme of rooftop rainwater harvesting system utilizing one of the astronomical building is discussed in the paper to sustain water requirements. Management of harvested water for the three buildings will be carried out with smart systems based on Internet of Things (IoT). As a drive towards self-reliance, various proactive customized steps are planned for rejuvenating the existing water supply and to create alternate supply for meeting growing and emergency demands.
