Trends of observation on wells, Remedial measures and feasibility studies of Hoskote taluk, Bangalore rural district, Karnataka, India

Hosakote is a Taluk in Bangalore Rural District. It’s headquartered at Hosakote town, 25 km away from Bangalore City.Currently, Hosakote depends on ground water (bore wells) as the main source of water supply. Due to depletion of rainfall year by year,overexploitation a n d less recharges, the yield from the borewells are diminishing considerably. In summer season, the water table goes much below thus creating scarcity of water. Hence, the ground water source is not dependable and there is an inevitable need to develop a project for alternate source of water supply. And as such this p a p e r presents the water problems in the Taluk, the reasons for the problems and remedies to correct the problems. The scope of this paper includes: i. Profiling of Hosakote Taluk and understanding their water requirements and demands. ii. Identifying environmental and social impacts of the suggested remedies and to suggest mitigation measures to overcome these impacts. A preliminary feasibility report entitled, Integrated Water Supply project for Hoskote Town (2012), prepared by Infrastructure Development Department (IDD), Government of Karnataka, presents the water supply system and scenario of the Taluk. The primary objective of the project is to explore feasibility to cater to existing & future water demand of Hosakote City by providing treated water from Doddakere Lake while supplementing the source of incoming water to the lake with water from Bellandur Lake after tertiary treatment. Bellandur Lake receives water primarily from Koramangala- Challaghatta Sewage Treatment Plant (STP) which treats the sewerage to tertiary level. A report entitled Ground Water Information Booklet, Bangalore Rural District; prepared by Central Ground Water Board, Ministry of Water Resources, Government of India, reports that most of Karnataka State’s ground water is in critical condition. It addresses the need to stop exploration of ground water and presents ways to improve the water resources of the Taluk
