On 11 November 2019, the MWSS Regulatory Office (RO) participated in the groundbreaking ceremony for the construction of the Caloocan-Malabon-Navotas (CAMANA) Water Reclamation Facility (WRF) project of Maynilad Water Services, Inc. (MWSI).

CAMANA WRF is set to be MWSI’s largest wastewater treatment facility that will significantly increase sewerage coverage in the West Zone of Metro Manila. It is designed to comply with the more stringent water quality guidelines and effluent standards enforced by the Department of Environment and Natural Resources (DENR). It is also part of the company’s program to aid in the rehabilitation of Manila Bay.
