Lakes: The Heritage of Bengaluru through Birds Eye
In the Deccan plateau, Bengaluru is an important cosmo metropolitan city comprised of more than ten million human population. The city is located at an average elevation of about 900 meters from the sea level with highly undulating terrain of upper profile good red soil. Due to this character, the areas underoccupied township have large number of manmade tanks primarily constructed for the purpose of agriculture/horticulture irrigation and drinking. The tanks are scattered in series of clusters linked to each other through channels in that cluster. All the tanks in the city are the part of either of hebbal valley or rishbhavathi valley or kormangla-chelghatta valley. The constructions of tanks in the city have a long history and goes back even to Ganga dynasty (350 to 1000 CE), bellanduru tank was constructed in that period. The tanks in Bengaluru are the heritage of the city and caused to call “City of lakes”. Most of the tanks are polluted and unfit for human use. Reuse of secondary treated water is one of the most difficult tasks before the Authorities. Treated water from STPs of koramangla-chelghatta valley is being used to fill the tanks of Kolar district. Twenty four tanks are filled until the last report. This article covers the essence of research works done in last thirty-four years.
