Manila Water Completes P5.7-Billion Submarine Pipeline for East Bay Project
Key Takeaways
- •Manila Water has finished constructing a P5.7-billion submarine transmission system spanning about 31.5 kilometers under Laguna Lake to move treated water from Pakil, Laguna, to Taguig City.
- •The pipeline can carry as much as 200 million liters per day of treated water from the East Bay Water Treatment Plant Phase 2.
- •The system consists of two underwater segments: a 13.2-kilometer Central Bay line from Jala-Jala, Rizal, to the Binangonan Peninsula, and an 18.3-kilometer West Bay line from the peninsula to Taguig City.
- •The completed lines are a component of the East Bay Phase 2 project and are expected to improve reliability and operational flexibility in Manila Water's east zone network.
- •Manila Water officials linked the project to long-term water security preparations for a possible strong El Niño event in 2027, but the company has not disclosed when the lines will begin delivering water.
Manila Water Co., Inc., the concessionaire serving Metro Manila's east zone, has completed a P5.7-billion submarine transmission system that will carry treated water from its East Bay Water Treatment Plant in Pakil, Laguna, to Taguig City.
In a statement on Wednesday, the company said the system consists of 1,200-millimeter-diameter submarine transmission lines spanning approximately 31.5 kilometers underwater across Laguna Lake, also known as Laguna de Bay, the largest lake in the Philippines.
The pipeline is designed to convey up to 200 million liters per day of treated water from East Bay Water Treatment Plant Phase 2 in Pakil. Transmission infrastructure of this kind serves as the conveyance link between a treatment facility and the distribution network of the communities it supplies.
The system comprises two segments: the Central Bay section, which runs 13.2 kilometers from Jala-Jala, Rizal, to the Binangonan Peninsula, and the West Bay section, which extends 18.3 kilometers from the Binangonan Peninsula to an onshore landing point in Taguig City.
According to Manila Water, the completed transmission lines form part of the East Bay Phase 2 project and are intended to improve system reliability and operational flexibility.
“The submarine transmission lines are a vital component of the East Bay Phase 2 project, serving as the critical link that will enable treated water from Laguna Lake to reach communities across our service area,” Manila Water Corporate Communications Head Dittie Galang said.
“Their completion brings us closer to realizing additional water supply that will help strengthen long-term water security for our customers, particularly as the country prepares for the potential impacts of a strong El Niño event in 2027,” she added. El Niño is a climate pattern typically associated with below-normal rainfall in the Philippines.
Manila Water serves the east zone of Metro Manila, covering parts of Marikina, Pasig, Makati, Taguig, Pateros, Mandaluyong, and San Juan, portions of Quezon City and Manila, and several towns in Rizal province. No timeline was given for when the completed lines would begin delivering water, leaving the remaining steps the East Bay Phase 2 project as the next milestone to watch for the additional supply.
