WATER DISTRIBUTION
Maynilad maintains and operates some 6,831 kilometers of primary, secondary and tertiary pipelines. If laid end-to-end from Manila, these pipes can reach United Arab Emirates in the Middle East.
The company also has 35 pumping stations, 32 water reservoirs and 28 in-line boosters across its service area. Its reservoirs have a total holding capacity of over 700 million liters of potable water.
The Maynilad water distribution system is the longest ISO-certified facility of its kind in the Philippines. It stretches from North Caloocan to Cavite Province and delivers over 2,000 million liters of potable water per day to over 1,400,000 million customers.
WATER TREATMENT
Maynilad maintains and operates four world-class water treatment plants.
La Mesa Treatment Plant 1 is a conventional-type plant with a maximum design capacity of 1,500 million liters per day (MLD). It was designed by American company Camp, Dresser and McKee.
La Mesa Treatment Plant 2 is a pulsator-type plant that has a design capacity of 900 MLD. It was designed by Degrémont, a French company recognized as a world specialist in water treatment plants.
Both treatment plants are ISO 9001:2015, ISO 14001:2015 and OHSAS 18001:2007-certified, which means that Maynilad’s water treatment process meets global standards for Quality Management and Environmental Management.
Putatan Water Treatment Plant 1 draws raw water from Laguna Lake and is the largest membrane-based water treatment plant in the Philippines. It is the first of its kind in the country to use large-scale microfiltration and reverse osmosis.
Putatan Water Treatment Plant 2 is also a membrane-based water treatment plant and has a design capacity of 150 MLD. It uses an advanced, multi-stage process for treating water to ensure delivery of potable water.
All four water treatment facilities produce water that meets the Philippine National Standards for Drinking Water (PNSDW) of the Department of Health (DOH).
WASTEWATER TREATMENT
Maynilad maintains and operates 19 Sewage Treatment Plants, two (2) Joint Sewage and Septage Treatment Plants, and one (1) Septage Treatment Plant that process wastewater and sludge collected from customers. This is to prevent the pollution of waterways and bodies of water.
Twenty out of the 22 facilities are certified in three standards, namely, the ISO 9001:2015 (Quality Management System), ISO 140001:2015 (Environmental Management System), and OHSA 18001:2007 (Health and Safety Management System). Aside from the three ISO certifications, the Tondo Sewage Pumping Plant is also certified under ISO 50001:2011 (Energy Management System).
