Tanks and water bodies form important surface water storage. The existing ponds and tanks available in the Urban Local Bodies have been silted over the years and thereby make the water bodies less functional for recharge. Under this restoration project, the water bodies will be de-silted, inlet and outlet will be cleaned from obstruction and the bunds will be strengthened. A recharge well or shaft within water bodies may be taken up wherever necessary depending upon the geological nature of terrain.

Apart from available rainwater and reuse of treated wastewater, waterbodies (lakes, ponds) especially in urban areas have enormous value in terms of resource provision (for drinking or irrigation), regulating services (climate mediation, flood and drought management) and cultural service (religious, historic value). However, these lakes and ponds are extremely sensitive to environmental stress caused by anthropogenic activities in the basin or catchment, which reduces the natural capacity of the waterbody to restore itself and results in its deterioration.
