MANILA, PHILIPPINES – A $60,000 wastewater treatment facility was today turned over to a Manila barangay in the first project of its kind to be managed by the community. The facility in Barangay 672, beside Estero de Paco, was funded under a grant from the Asian Development Bank (ADB) and implemented by the Pasig River Rehabilitation Commission (PRRC).

Members of the Sangguniang Barangay and the neighborhood association, the Kilusang Pang-kapitbahay at Pang-kabuhayan, Inc. (KPPI), will run the facility.

More than 60 percent of the pollution load into Pasig River and its tributaries, like Estero de Paco, are from domestic wastewater.

The new facility will treat domestic wastewater from at least 58 houses in the community where only 6 to 7 septic tanks exist. The wastewater will be collected through a network of sewer pipes leading to a sump pit where the wastewater is stored temporarily. From the sump pit, the wastewater is conveyed to an anaerobic baffled reactor (ABR) with the help of solar-powered submersible pumps. From the ABR, the wastewater is further treated in a constructed wetland before it is released to the estero.

During rainy months, the system will automatically connect to the Meralco grid, with the minimal electricity bill to be borne by the KPPI’s membership.

An Operations and Maintenance Committee was organized, consisting of members from the Barangay Council and KPPI, to monitor and ensure that the facility functions optimally.

The committee will be supported by the City Government of Manila, PRRC and various agencies, such as Department of Environment and Natural Resources, Department of Health, Department of Public Works and Highways, Metropolitan Manila Development Authority, Metropolitan Waterworks and Sewerage System, Maynilad Water Services, Inc., and the Kapit-Bisig Para sa Ilog Pasig of the ABS-CBN Foundation.
