The Department of Environment and Natural Resources (DENR) opened a solar-powered sewage facility in Manila Baywalk as part of the Manila Bay rehabilitation program.

According to DENR Secretary Roy Cimatu, the facility is the first of its kind in the Philippines as it will treat water coming from the three waterways. These waterways are Padre Faura Drainage, Remedios Drainage, and Estero de San Antonio de Abad, which were all located in Malate, Manila, before being discharged to Manila Bay.

The treatment plant can reach 500,000 liters of water at any given time and store up to 2,000,000 liters of water in its tanks.

So far, the test on July 29 showed that the coliform level of water that passed through the plant has significantly dropped to 770 MPN/100mL. The DENR aims to achieve the “swimmable level,” which is on 200 MPN/100mL.

“Let us see how the water treats itself,” said Cimatu. “Because it is also treating itself. If nothing contaminates it, it normalizes on its own, and we can expect a 200 MPN.”

The Metropolitan Manila Development Authority (MMDA) will handle the maintenance and operations of the water treatment plant.
