Founded in 1997, the Manila Water Company (MWC) serves the potable water needs of more than five million residents of the Philippines capital and cities to the east. MWC's Balara water facility consists of two separate treatment plants in Quezon City: Balara 1, with a design capacity of 470 mld (124 mgd); and Balara 2, with a design capacity of 1,130 mld (298 mgd).

Both plants had produced adequate quantities of water to acceptable standards of quality. Only during extreme weather conditions, such as typhoons, had water quality fallen below expectations. Faced with anticipated regional population growth and ever-tightening water quality regulations, MWC underwent an exploratory study and then a pilot project to determine expansionary requirements that would enable the company to optimize operational performance and meet water quality and flow demand requirements at the Balara facility.
