WABAG has been commissioned by Metro Manila to upgrade La Mesa-2, the world’s ninth largest drinking water treatment plant

WABAG was recently awarded the contract for the plant retrofit and upgrade with a value of USD 60 million together with a JV partner. The La Mesa-2 WTP produces 900,000 m3 of water per day and is one of three Metro Manila drinking water plants, which ensure the safe supply of clean water to the megacity. The plant will be refurbished and receive a technical upgrade during continuous operation over the course of the next 3 years.

WABAG Philippines won the contract for the retrofit, rehabilitation and upgrade of the large-scale La Mesa 2 water treatment plant in Quezon City in October 2017. The plant produces 900,000 m3/d for around five million people in the Manila metropolis and the project, which has a total contractual value of USD 60 million, will be realized together with a local civil JV partner.

The Angat River is the largest and most important water source for Metro Manila. The water is stored in reservoirs and then treated in the La Mesa 1 &2 and Balara plants to make it potable. The plants employ four main treatment steps consisting of coagulation/flocculation, sedimentation, filtration and disinfection. However, over the years, the technology employed at La Mesa-2 WTP has become outdated and therefore requires refurbishment and modernisation. The resultant project also foresees additional features such as the handling of high raw water turbidity (2,000 NTU) and a structure capable of withstanding a 7.2 magnitude earthquake.

During continuous plant operation, WABAG will convert the existing pre-treatment technology (Pulsator) into modern lamella clarification and single-layer sand filtration will be modified to provide highly effective dual media filtration. The scope of supply includes design and engineering, equipment, installation and commissioning. After completion, which is scheduled for the end of 2020, WABAG will also be responsible for process proving for one year.

Founded in 2011, during the past seven years WABAG Philippines has completed a series of national water technology projects, including seven wastewater treatment plants. The La Mesa-2 WTP is the second project in the drinking water treatment field to be obtained following the refurbishment and upgrading of the Putatan WTP with a capacity of 150,000 m3/d using advanced WABAG filtration technology. Furthermore, the company has been commissioned by the Manila Water Company (MWC) to build and run a pilot plant for the Philippines’ first septic waste to energy (WTE) project. The WTE facility, which has already undergone successful testing, utilizes septage or waste materials removed from septic tanks, as a feed source.

Coleridge Shelley, the WABAG Philippines CEO: “We are very happy that our client, Maynilad Water Services Inc., has awarded this ambitious project to WABAG. As a technology leader we were able to provide an individual and optimal technological solution based on our comprehensive, multinational experience and the support of our international team of top technical experts.”
