Manila Water assures its customers in the East Zone that water supply is sufficient even amid the threat of COVID-19. This is due mainly to the augmentation sources the company has started putting in place beginning last year, such as the Cardona Water Treatment Plant in Rizal and deep wells, as well as non-revenue-water recovery. Skeleton workforces are also on duty at every water supply and wastewater facility to ensure that service delivery remains unhampered.
