Distribution Network
Water withdrawal and production rates at Maynilad are dependent on customer demand and water delivery.
Raw water coming from Angat Dam that is meant for domestic use is transmitted to Metro Manila through Ipo Dam, a diversion dam, 7 kilometers downstream of Angat, in Norzagaray, Bulacan. The Ipo Watershed, meanwhile, straddles three municipalities: Norzagaray and San Jose Del Monte in Bulacan, and Montalban in Rizal. Runoff within the watershed is conveyed through its main tributary rivers namely, Sapang Anginan, Sapang Binenet, Sapang Ipo, and Sapang Paco.
Water released from Angat Dam is transmitted through Ipo Dam, and treated at the two plants in La Mesa, namely, La Mesa Treatment Plants 1 and 2. Another source of water is Laguna de Bay, a lake in southern Luzon. Water from the lake is treated at the Putatan Water Treatment Plant or PWTP, the country’s largest Water Withdrawal membrane-based water treatment plant that pioneered the use of large-scale microfiltration ultrafiltration and reverse osmosis. After raw water is treated at the plants, it is then ready to be distributed to customers.
To manage the delivery of water and wastewater services in the West Zone, Maynilad has divided its service area into 12 BAs that are further broken down into zones, sub-zones and District Metered Areas (DMAs). These DMAs service over one million accounts, providing piped-in water supply to the West Zone.
The Company distributes water through 7,306 kilometers of primary, secondary and tertiary pipelines which, if laid end to end, will stretch from Manila all the way to Qatar. The distribution system also includes 24 pumping stations and 24 water reservoirs spread across the West Zone, with a total holding capacity of 559 million liters.
