One of the vital functions of the MWSS Regulatory Office (RO) is to analyze and evaluate the financial condition and operation of Manila Water Company, Inc. and Maynilad Water Services, Inc. by conducting regular, independent financial audit of the activities of the two concessionaires, and monitoring the submission of audited financial statements.
Under the Concession Agreement, the MWSS RO Financial Regulation Area (FRA) is responsible for regulatory accounting, rate adjustment, and economic functions.
These functions are handled by two departments: The Financial Audit and Asset Monitoring Department (FAAMD) performs regular and methodical regulatory accounting and asset monitoring; the Tariff Control and Monitoring Department (TCMD) performs rate determination and monitoring of tariff adjustment compliance and selected key economic and financial indicators.
