Maynilad’s Water and Wastewater Services

Water is crucial, covering 70% of Earth and making up 75% of the human body. However, only 1% of the Earth's water is fresh, with 98% of that used for agricultural and industrial purposes. This leaves a mere 2% for human consumption, highlighting Maynilad's vital role in sustainably delivering water to its 9.5 million customers.

Maynilad's primary water source is the Angat-Ipo-La Mesa water system, supplemented by the Umir River. The Angat Dam, a multi-purpose dam in Bulacan, supplies 98% of Metro Manila's raw water. Water is released from Angat to the Ipo Dam, then travels through tunnels and aqueducts to the Novaliches Portal. From there, 60% of the water goes to Maynilad and 40% to Manila Water, eventually reaching treatment facilities at La Mesa Dam.

The water undergoes several treatment stages at La Mesa. Treatment Plant 1 uses a conventional method involving bar screens, pre-chlorination, coagulation, and filtration. Treatment Plant 2, a more compact facility, follows a similar process with bar screens, pre-chlorination, coagulation, polymer addition, pulsator clarifier basins for impurity removal, and then filtration and disinfection.

The Putatan Treatment Plant, the first to tap into Laguna Lake, utilizes microfiltration and reverse osmosis to meet the demands of southern consumers. This state-of-the-art plant employs a multi-stage process including dissolved air flotation, microfiltration, reverse osmosis, and chlorination, ensuring the water meets Philippine national standards for drinking water. All treated water is rigorously tested by Maynilad chemists to assure its safety and potability.

After treatment, potable water travels through secure pipes, reservoirs, pumping stations, and mini boosters. The Water Network Department manages pressure to ensure efficient flow to customers. The Non-Revenue Water Division protects and maintains pipes, minimizing losses from damage and ensuring a constant supply. Maynilad business area offices manage deliveries, address shortages, handle billing, and prevent illegal connections.

Maynilad operates five major wastewater treatment plants. Wastewater from households, either through sewage pipes or septic tanks, is collected for treatment. Maynilad also provides septic tank cleaning. The wastewater undergoes three stages: primary treatment removes solid contaminants, secondary treatment eliminates biological matter, and tertiary treatment disinfects the processed water. Maynilad uses advanced technologies like sequencing batch reactors and moving bed biofilm reactors.

After meeting Maynilad's high standards, treated wastewater is released back into various bodies of water surrounding Metro Manila. This sustainable approach ensures the continuous provision of services for future generations, delivering safe, affordable, and sustainable water solutions to enhance healthier and more comfortable lives. Maynilad aims to be a leader in providing excellent water services.
