Dharwad City at one time famous as retired persons paradise was cool and calm and was recognised as educational centre. Dharwad was once bestowed with number of tanks, which served as lungs for the city and also supplied water to the people and animals of city. Rapid urbanisation and increasing population compelled the authorities concerned to convert many of these tanks in to commercial/residential centres, ultimately converting them in to concrete jungles.

There are still some more tanks,   waiting either for total denudation or all-round development to bring back their old glory and one such among them is Kolikeri Tank.

The sewage from the southern part of city is disposed off by a network of sewerage system, the out let of which is near the said Kolikeri tank. Since the sewerage is very old and there is lack of maintenance from local Corporation Body, there is breakdown of system and the sewage is getting mixed with water of Kolikeri tank. This has resulted in converting the tank in to a sewage body, over a period of two decades and is completely covered with water hyacinth. It has become a breeding place for mosquitoes leading to health hazards and has rendered the tank unfit for normal usage.

It is proposed to restore and develop the tank and convert it in to a useful water body and a recreational centre . This has necessitated a detailed survey and study regarding its location ,boundaries, the extent of area, present condition regarding pollution level and its utilization for different purposes.

This paper aims at studying the restoration of tank by desilting the organic material deposited and diverting the sewage and allowing only the storm water in to the tank.
