And whereas the study carried out by Indian Space Research Organization in association with Indian Resources Information and Management Technologies Pvt. Ltd., (IN-RIMIT) reveals that unplanned development in the catchment area is one of the main reasons for the deteriorating quality and reduced inflow into the reservoir. Increasing urbanization and industrialization in the catchment area is one of the main reasons for the deteriorating quality and reduced inflow into the reservoir. Increasing urbanization and industrialization in the catchment area has altered the drainage pattern in the catchment areas. This in turn has affected the inflow into the Tippagondanahalli Reservoir. There are number of industries in the catchment area, whose effluents also flow into Tippagondanahalli Reservoir affecting the quality of water. Underground leachate from untreated effluent and sewage is also affecting the quality of ground water in this area.
And whereas the total extent of Tippagondanahalli Reservoir catchment is 1453 sq km and covers parts of Doddaballapur, Nelamangala, Devanahalli, Magadi and Bangalore taluks. Tippagondanahalli Reservoir receives inflows from two streams namely Kumudvathi and Arkavathi. This study done by ISRO and IN-RIMT, has made several recommendations, to protect and preserve the Tippagondanahalli Reservoir catchment. The recommendations include as follows:
Formation of a Conservation Zone covering the entire Tippagondanahalli Reservoir catchment and adopting suitable land utilization strategy therein, especially from the point of view of regulating the urbanization/industrialization.
