Concession Agreements and Republic Act No. 11600
Maynilad operates under a dual legal mandate combining regulatory concession rights and direct statutory authority:
- Revised Concession Agreement (RCA): Signed on May 18, 2021, with the Metropolitan Waterworks and Sewerage System (MWSS), clarifying tariff methodologies, service obligations, and confirming continuity through July 31, 2037.
- 25 Year Direct Legislative Franchise: On December 10, 2021, Republic Act No. 11600 was signed into law, granting Maynilad a congressional franchise to establish, operate, and maintain waterworks and sewerage systems across the West Zone until 2047.

Concession Service Coverage: 17 Local Government Units
The West Zone concession boundary divides Greater Metro Manila and Cavite, giving Maynilad complete operational responsibility for water distribution and sewerage services across 17 distinct local government units.
Metro Manila Service Territory (11 LGUs)
Maynilad supplies potable water to both entirely covered and specifically partitioned cities in the western and southern sectors of the National Capital Region (NCR):
Cavite Province Concession (6 LGUs)
In addition to Metro Manila, Maynilad extends piped water access, sewer systems, and customer assistance into key urbanized and coastal local government units across Cavite:
Water Treatment Facilities & 2026 El Niño Resilience
Facing shifting tropical rainfall patterns and prolonged dry spells, Maynilad has invested heavily to diversify raw water extraction away from sole dependence on Angat Dam while completing near ₱10 billion in facility overhauls at the La Mesa complex.
La Mesa Treatment Plants 1 & 2 Upgrades
Located in Quezon City, the La Mesa Treatment complex processes raw water delivered through aqueducts from Angat and Ipo Dams. In October 2026 updates reported by INQUIRER.net and ABS-CBN News, Maynilad disclosed spending nearly ₱10 billion over recent years to modernize these installations.
- Turbidity Management: Upgraded sedimentation basins and flocculation systems capable of treating raw water during high turbidity storm events.
- Sludge Treatment Facility: State of the art mechanical dewatering system that reclaims residual backwash water and minimizes production loss.
- Plant 1 & 2 Overhauls: Full automation of dosing chemicals and retrofitting of aging filtration beds.
Laguna Lake Source Diversification
Historically, over 90% of Maynilad water came exclusively from the Angat, Ipo, and La Mesa reservoir cascade in Norzagaray, Bulacan. Through strategic expansion, Maynilad has successfully lowered Angat reliance down to approximately 83% by treating raw water from Laguna de Bay:
- Putatan Water Treatment Plants 1 & 2: 300 million liters per day (MLD) combined capacity using ultrafiltration and reverse osmosis in Muntinlupa.
- Poblacion Water Treatment Plant: 150 MLD advanced facility tapping Laguna Lake to serve Parañaque, Las Piñas, Muntinlupa, and Cavite.
- Central Cavite Modular Plants: Compact modular filtration installations addressing isolated demand pockets.
El Niño Operational Protocols
To cushion communities against severe droughts and reservoir depletion, Maynilad maintains multitier preparedness protocols during declared El Niño seasons:
- Deep Well Reactivation: Over 70 certified backup groundwater wells placed on standby to augment peak day domestic consumption.
- Mobile Water Tanker Fleets: Deployment of stationary static water tanks and mobile refilling trucks to hospitals, schools, and elevated barangays.
- NRW Leak Recovery: Aggressive acoustic leak detection programs recovering treated water lost through aging underground transmission networks.
Wastewater Treatment, Sewerage & Environmental Sustainability
Sanitation and ecological wastewater reclamation represent half of Maynilad's concession mandate under the Philippine Clean Water Act of 2004 (Republic Act No. 9275), preventing toxic untreated effluents from polluting Manila Bay.
Las Piñas Water Reclamation Facility (WRF)
The flagship Las Piñas Sewage Treatment Plant and Water Reclamation Facility represents one of the largest modern biological wastewater treatment installations in the country. Designed to treat 88 million liters of wastewater per day (88 MLD), the facility provides biological nutrient removal before releasing clean effluent into the Zapote and Las Piñas River systems.
- Treatment Capacity
- 88 Million Liters per Day (88 MLD)
- Beneficiary Population
- Over 360,000 residents across 20 Las Piñas barangays
- Environmental Standard
- DENR Administrative Order (DAO) 2016-08 / DAO 2021-19 compliant
- River Basin Protection
- Directly safeguards Zapote River, Las Piñas River, and Manila Bay
Network STPs & Residential Desludging Programs
In addition to dedicated piped sewerage interceptors, Maynilad operates localized sewage treatment plants and septage facilities across its territory:
- Regional Treatment Network: Active facilities in Dagat-Dagatan (Caloocan), Talayan (Quezon City), San Antonio (Parañaque), and Valenzuela.
- Free Domestic Septic Tank Siphoning: Regular scheduled desludging services provided at no additional cost to residential consumers with updated accounts.
- Septage Treatment Plants (SpTP): Specialized septage drying and anaerobic digestion installations in Northern and Southern concession hubs.
Roadworks, Pipe Replacement & Traffic Awareness
As widely observed by drivers on motoring communities such as r/Gulong along arterial corridors like Daang Hari, ongoing pipeline rehabilitation and excavation represent essential engineering steps to upgrade decades old water networks.
Understanding Pipe Replacement along Daang Hari
Commuters and motorists frequently observe active excavation trenches along Daang Hari Road connecting Las Piñas, Muntinlupa, and the Cavite municipalities of Bacoor and Imus. While these projects inevitably impact traffic flow, they serve critical operational objectives:
- Non Revenue Water (NRW) Reduction: Replacing fragile, pre concession cast iron pipes with modern high density polyethylene (HDPE) and ductile iron to prevent silent underground leaks.
- Water Pressure Boost for the South: Installing primary transmission conduits to convey clean output from the Poblacion and Putatan plants into high demand residential subdivisions in Cavite.
- Sewer Interceptor Laying: Embedding gravity sewerage lines beneath major road rights of way to funnel wastewater toward the Las Piñas treatment facility.
Road Safety Protocols & Motorist Guidance
To mitigate inconvenience and ensure road safety, Maynilad contractors adhere to mandatory Department of Public Works and Highways (DPWH) and local traffic management bureau standards:
- Steel Trench Plates (Bakal Plates): Deep excavations in active vehicular lanes must be bridged with certified steel plates during daytime traffic hours.
- Night Shift Excavation Schedules: Major pipe interconnections and road cutting occur predominantly between 10:00 PM and 5:00 AM to prevent daytime gridlock.
- Asphalt Restoration: Contractors must apply temporary asphalt cold patch immediately after backfilling, followed by permanent concrete pouring within prescribed permit deadlines.
- Hazard Warning Lights & Signage: High visibility barricades, reflective directional signs, and blinking warning lamps are required at every open pit.

What upgrades were completed at the La Mesa treatment plants for El Niño resilience?
Maynilad invested nearly ₱10 billion to overhaul La Mesa Treatment Plants 1 and 2 in Quezon City. Key enhancements include retrofitted sedimentation basins capable of treating high turbidity water during monsoon downpours, a specialized mechanical Sludge Treatment Facility to reclaim backwash water, and automated chemical dosing systems. These works ensure continuous potable output even when raw reservoir conditions fluctuate severely during El Niño.
Why are there frequent excavations and metal plates along roads like Daang Hari?
Road excavations along thoroughfares such as Daang Hari are part of Maynilad's Non Revenue Water (NRW) reduction and southern network expansion. Crews replace aging, leak prone underground pipes with high grade ductile iron and HDPE pipelines to bring water from the Poblacion and Putatan Laguna Lake plants to Cavite subdivisions. Heavy steel plates (bakal plates) are placed over trenches during the day to keep lanes passable while work continues under nighttime road permits.
Who owns and operates Maynilad Water Services, Inc.?
Maynilad is operated by Maynilad Water Holding Company, Inc., a joint venture conglomerate comprising Metro Pacific Investments Corporation (MPIC), DMCI Holdings, Inc., and Japan's Marubeni Corporation. Manuel V. Pangilinan serves as Chairman of the Board, while Ramoncito S. Fernandez serves as President and Chief Executive Officer. The company is publicly listed on the Philippine Stock Exchange under the ticker MYNLD.
What is Republic Act No. 11600 and how does it affect Maynilad?
Signed into law on December 10, 2021, Republic Act No. 11600 granted Maynilad a 25 year direct legislative franchise to operate, construct, and maintain water and wastewater services across the West Zone until 2047. This statutory public utility charter operates alongside the May 18, 2021 Revised Concession Agreement (RCA) with the Metropolitan Waterworks and Sewerage System (MWSS), which remains valid through July 31, 2037.
Does Maynilad provide free septic tank cleaning (desludging) services?
Yes. Residential customers with active accounts are entitled to regular septic tank cleaning and desludging at no additional fee. Maynilad deploys vacuum tanker trucks according to pre announced barangay schedules published on mayniladwater.com.ph and verified via the 1626 hotline. Septage collected is transported to dedicated septage treatment facilities for biological processing.
What should customers do when water service resumes after a repair interruption?
When supply is restored following network maintenance, trapped air or mineral deposits in the distribution pipes may cause brief initial water discoloration. Customers are advised to let faucets run for one to two minutes until water flows crystal clear. This flushed water can be collected and used for watering plants or flushing toilets to avoid waste.
