The project is composed of an 80 million litre per day (MLD) capacity water treatment plant (WTP), pumping stations, reservoirs, and 21 kilometres of primary transmission line. It is expected to provide treated water to 919,784 population.
WD News: Manila Water, Philippines, expects the construction of its P8.2 billion Calawis Water Supply System Project to be completed in June 2023. The raw water for this facility comes from the Tayabasan River, located in Brgy. Calawis, Antipolo City. This area is part of the Upper Marikina Watershed, which Manila Water is helping to grow and maintain.
At present, while preparing to commence full operations, the facility is already able to supply treated water to some areas of the city including the Antipolo Government Centre. The Calawis Water Supply System Project is composed of the 80 MLD water treatment plant (WTP), pumping stations, reservoirs, and 21 kilometers of primary transmission line.
The WTP used Degremont Compact Units (UCD), which are prefabricated, modular water and wastewater treatment plants engineered for efficient production, transportation, and installation. This technology significantly reduces footprint requirement and time for construction. The project also used pipe jacking technology, a trenchless method of installing pipes, on a portion of pipelaying contract and for the two river crossings to bring potable water to the customers.
The Calawis Water Supply System Project is part of the company’s Water Supply Masterplan, which aims to ensure water security and supply reliability in the East Zone for the next decades, while lessening dependence on Angat Dam.
