The Department of Environment and Natural Resources is now requiring all establishments within the Manila Bay area to connect to existing sewer lines or set up their own sewerage treatment plants to ensure that wastewater is properly collected and treated. Environment Secretary Roy Cimatu, chairperson of the inter-agency Manila Bay task force, issued Memorandum Circular 2019-01 covering all government facilities, subdivisions, condominiums, commercial centers, hotels, sports, and recreational facilities, hospitals, marketplaces, public buildings, industrial complex, and other similar establishments. “The Manila Bay region covered by the circular encompasses the entire bay coastline of 190 kilometers and the total drainage area of about 17,540 square kilometers across Regions III, IV-A and the National Capital Region,” Cimatu said.
