Detailed Project Report for Sewerage (11 ULBs) and Storm Water Drainage System (13 ULBs) of Telangana (Package II) (Project Cost : Sewerage INR 17351 Million) (Project Cost : Storm Water Drainage INR 17143 Million)

Funding Agency: International Bank for Reconstruction and Development (IBRD)

Location: Telangana

Water Supply and Sanitation provision are the most conspicuous of municipal activities. Lack of planned capital investment and inadequate operation and maintenance, combined with a growing population demanding higher service levels has reduced the effectiveness of water supply and sanitation services in many municipalities. Inadequate sanitation and wastewater management has been an essential issue in many urban local bodies. In most of the towns, there is no sewerage system or it covers only a part of the town. Government of Telangana has takenup the ULBs in Packages to provide adequate water supply and waste water management.
