Three solar-powered sewage treatment plants to be built to protect Manila Bay

  • DENR Secretary Roy A. Cimatu said they will be building three solar-powered sewage treatment plants (STPs) for the rehabilitation of Manila Bay
  • Cimatu said this is part of the government’s efforts to rehabilitate and protect Manila Bay
  • The treated water that comes from the STPs will be used to water the plants, maintain the comfort rooms around Roxas Boulevard and for fire departments in Manila and Pasig

DENR Secretary Roy A. Cimatu said that three solar-powered STPs will be installed along major river systems that drain into Manila Bay: the Libertad outfall in Parañaque River, Tullahan-Tinajeros River, and Las Piñas-Zapote River.

He said that the installation of the additional three STPs are part of the government’s efforts to ensure that no untreated wastewater from  three drainage outfalls, namely Padre Faura, Remedios and Estero de San Antonio Abad, will drain into the Manila Bay. He said its construction is “just one of the many geo-engineering interventions” for cleaning Manila Bay.

“The STP is a big step forward to making Manila Bay safe again for swimming, bathing, boating, fishing and other forms of contact recreation,” said Cimatu, who chairs the Manila Bay Task Force in charge of rehabilitating the iconic Bay.

Cimatu explained that the STPs will recycle and store the untreated water in an underground tank which has a capacity of 2 million liters. Once the water becomes treated, it will be used to water the plants along Roxas Boulevard. It will also help maintain the planned solar-powered comforts rooms to be constructed at the bay walk area. The treated water will also be beneficial to the fire departments of Manila and Pasay City.

President Rodrigo Duterte had earlier approved the budget of P43 billion for the implementation of the Manila Bay rehabilitation project within three years.
