Manila gets plant that treats water from estero, wet market

MANILA, Philippines — A technology firm has turned over to the Manila City government a plant that uses locally developed technology to treat water from the Paco Estero and wet market for non-potable reuse.

Ecosystem Technologies International Inc., in a statement, said the “sequence bio-reactor” used in its Paco Estero plant is able to generate an effluent level of 10 milligrams per liter or less of Biochemical Oxygen Demand (BOD), which it said is the highest quality for non-potable water reuse based on standards of the US Environmental Protection Agency.

This effluent level far exceeds the Department of Environment and Natural Resources’ standard in BOD — a measure of how much oxygen is needed to allow for waste’s decomposition — of 50 mg per liter.

The water treated by the Paco plant — a combination of household wastes, sewer backflow, intrusion from the Pasig River and Manila Bay, rain, and floodwater — can be used for cooling towers, irrigation and toilet flushing, ESTII said.

The plant was a partnership between ESTII and the ABSCBN Foundation, in coordination with DENR. It collects 220 cubic meters of waste water daily.

The SBR technology employed at the Paco facility can be replicated to treat other polluted rivers and water systems in the country.

For example, ESTII president and CEO Robert So said, “There are 49 tributaries connecting to the Pasig River. There can be similar plants as that in Paco Estero that may be put up there to provide clean water for non-potable use to communities around Pasig River.”

ESTII bills itself as “a pioneering leader of Total Water Resources Management, holding over 10 proprietary patents and technologies” in the country.

It has “designed and built over 500 used water treatment plants/water reclamation facilities in the country,” including for Ayala Land properties and malls, SM Malls and properties, San Miguel Corp., Greenhills Shopping Center, Yazaki Torres, Jollibee Commissaries, National Book Store, New Medical City, Petron, De La Salle University, Sisters Of Mary Boys Town, Villa Escudero Plantation and Resort, Chinese General Hospital, Victor R. Potenciano Medical Center, Puregold Supermarket, and Shopwise.
