Corporate Governance

The Metropolitan Waterworks and Sewerage System Regulatory Office (MWSS RO) was created in August 1997 by virtue of the Concession Agreements signed between the MWSS and the two Concessionaires: Manila Water Company, Inc. (Manila Water) for the East Zone and Maynilad Water Services, Inc. (Maynilad) for the West Zone.

The MWSS RO is mandated to monitor the performance of the Concessionaires with respect to their contractual obligations under the RCAs. Among its many functions, the MWSS RO reviews, monitors and enforces rates and service standards; arranges and reports regular independent audits of the performance of the Concessionaires; and monitors the infrastructure assets.
