Subic Water and Sewerage Co., Inc (SUBICWATER) is Southeast Asia's pioneer company which introduced the first public-private partnership (PPP),
build-operate-and transfer (BOT) model in the water and wastewater services industry. The company was formed in light of the impending water crisis
in Olongapo City during the '90s, and the growing commercial water requirements of the booming Subic Bay Freeport Zone.
SUBICWATER is a consortium of D.M. Consunji Inc. (DMCI), a Filipino construction firm; Sembcorp Industries Ltd., (sembcorp) a Singaporean water utility specialist; the City Government of Olongapo; Subic Bay Metropolitan Authority (SBMA), the agency that administers Subic Bay Freeport; and Maynilad Water Services Inc. (Maynilad), the Philippines' largest water concessionaire in terms of customer base.
The company was granted the exclusive right and privilege to operate, maintain, and improve the water and sewerage systems of Olongapo City and Subic Bay Freeport under a 30-year franchise term.
SUBICWATER officially commenced operations in April 1, 1997.
In pursuit of delivering world-class services to customers, SUBICWATER became the first ISO-certified water utility in South East Asia.
At present, SUBICWATER is certified to comply with ISO 9001:2008 (Quality Management System), ISO 14001:2004+Cor 1:2009 (Environmental Management System), and OHSAS 18001:2001 (Occupational Health and Safety Management System).
