Desalination System


Desalination is the process of turning seawater into potable drinking water by removing the salinity or salt components.

Mactan Rock’s biggest water system is a 22,000 Cubic Meter per Day (CMD) seawater facility in South Road Properties-Cebu City which supplies SM seaside and City de Mari of Filinvest. Mactan Rock also has a brackish water facility installed in Waterfront Hotel and Casino supplying the hotel requirements and this is also distributed to Cebu Buisness Park supplying Ayala Mall and Cebu Holdings. Mactan Rock also has a 2,000 CMD sea water system installed in Mabolo-Cebu which supplies SM City, Radission Blu and APM Mall. Similarly, a 2,000 CMD system is on-going installation in SM Iloilo, which is an expansion from the existing water supply of 600 CMD. Our equipment is being expanded to match the growing requirement of SM Iloilo as the mall expands.

Mactan Rock also serves private communities, we have a sea water facility established in Coral Point Gardens in Punta Engano, Mactan which also supplies Discovery Bay of Sta. Lucia and Amisa of Robinland. Another water system is also installed for the residents of Pacific Grand Villa of Phil Estates in Suba Masulog, Lapulapu and another for Vistamar residences of Sta. Lucia in Dapdap, Lapu-lapu. Both water systems are treating brackish or saline water sources.
