Maynilad Water Services Inc. (MWSI) won the right to operate the franchise area for 25 years (1997-2022) for the treatment and distribution of potable water in the West zone area on 1 August 1997.
Originally, Maynilad was a partnership between the Benpres Holdings Corporation, the flagship company of the Lopez group, and Suez Lynnaise des Eaux of France, a prominent leader in the water industry, supplying drinking water to millions of people worldwide. However, in 2006, because of the financial and economic downturn experienced by its previous owners, MWSS and the Lopez group agreed to pre-terminate their contract.
In December of the same year, D.M. Consunji Inc (DMCI) and Metro Pacific Investments Corporation (MPIC) won the bid for 84% of the Maynilad shares and the unexpired term of the Lopez group.
Maynilad manages and operates the water and waste-water services in the cities of Manila (except San Andres), Pasay, Paranaque, Caloocan, Muntinlupa, Las Pinas, Valenzuela, and parts of Makati and Quezon City, including the municipalities of Navotas and Malabon. Its franchise area also covers Cavite City, and its municipalities of Bacoor, Imus, Kawit, Noveleta, and Rosario.
Maynilad has 4 business areas, namely: Northeast Business Area, Northwest Business Area, Central Business Area, and South Business Area.
