Eptisa will carry out an Options Study of South Caloocan, Malabon and Navotas Sewerage System in Philippines

The objective of the present study is to identify and assess the different sewage treatment and collection options to help in the reduction of pollution in Manila Bay

September 22 2014

The World Bank has awarded Eptisa a new consultancy services project to carry out an Options Study of South Caloocan-Malabon-Navotas Sewerage System during four months. The beneficiary of this project is Maynilad Water Services, Inc. (“Maynilad”), which is the water and wastewater services provider for the 17 cities and municipalities in Manila Metropolitan Area, comprising the West Zone of the Metropolitan Waterworks and Sewerage System’s (“MWSS”) franchise area. It covers a total land area of 540 km2 and a total population of about 9.5 million.

The objective of the present study is to identify and assess the different sewage treatment and collection options to help in the reduction of pollution in Manila Bay and its tributaries within the South Caloocan-Malabon-Navotas catchment, improving significantly the sanitation condition in the affected areas. This project is part of Maynilad’s commitment to accelerate sewerage and sanitation projects in order to help improve environmental condition of Manila Bay.

The Option Study will consider alternatives for the wastewater collection system, main interceptors, combined sewer overflow (CSO) structures, and the number, location and process technology of sewerage treatment plants. Eptisa will perform all necessary investigations to determine the best possible option of constructing the South Caloocan-Malabon-Navotas STP and conveyance system that will be undertaken by Maynilad.

This will include the study and recommendation of various alternative implementation schemes to ensure project viability. We will assess and evaluate the project area, identify/verify catchment area through creek sub-basin approach, identify all potential STP sites, identify pipe routes, sewage collection and treatment alternatives, and propose the best solution/option based on a technical, social and economic considerations.

The cities of South Caloocan, Malabon and Navotas are part of the Northern Area of Metro Manila with a total land area of approximately 4,400 ha and an estimated population of 1,100,000 people. The cities are geographically prone to flood especially during rainy season and high tide.
