The Manila Third Sewerage Project, approved by the World Bank in June 2007, is the fourth project financed under the investment fund. It builds on the IBRD Manila Third Sewerage Project, which supports wastewater collection and treatment in Metro Manila. The GEF project is designed to remove barriers to investment in sewerage and sanitation and to pilot cheaper treatment technology for disposal of seepage. Identifying roles of different agencies in the wastewater sector and gaps and overlaps in their responsibilities is also an important task of the GEF project. Metro Manila has seventeen local government units, which need to coordinate their efforts in improving sanitation services with many government agencies and the private sector, such as the Department of Environment and Natural Resources, the Laguna Lake Development Authority, the Pasig River Rehabilitation Commission, and the Metropolitan Waterworks and Sewerage System and its two concessionaires. The GEF project will also enhance the capacity of local government units to raise fund to finance municipal wastewater collection and treatment.
