Abstract

Public markets in the Philippines and around Asia pose significant challenges for wastewater treatment due to the relatively high strength of the discharges and variability of flows. The Muntinlupa Public Market, located in Muntinlupa City in the southern part of Metro Manila, is one of the largest public markets in the metropolitan area with 1,448 stalls and 24 hours a day operation. With support from the U.S. Agency for International Development for planning and design, the city constructed a treatment facility which began operating in February 2006. The wastewater treatment system is an innovative combination of anaerobic and aerobic treatment coupled with filtration using cocopeat media to meet local discharge standards. It also includes a water recycling system that will allow re-use of the treated effluent for flushing toilets, watering plants and street cleaning. This technology is being applied elsewhere in the Philippines and is suitable for other locations in the region.
