East Zone concessionaire Manila Water led the Adopt-an-Estero memorandum of agreement ceremonial signing together with the Department of Environment and Natural Resources (DENR) and several local government units (LGUs) to fully implement the cleanup and rehabilitation of San Juan River and its tributaries. The program further underscores the commitment of each partner-agency to address pressing issues about the environment. The event also marked the signing of an updated usufruct agreement between the DENR and Manila Water for the upgrading of the East Avenue sewage treatment plant in Quezon City.
