In the late 1990s MWSS privatized its operations in MM to two concessionaires: the western part to Maynilad Water Services Inc. (MWSI) and the eastern part to Manila Water Company Inc. (MWCI). Expansion of the services in the concessions is defined in terms of 5-year targets. In order to interpret their sewerage targets, the concessionaires amended the respective master plans for each operational area. MWCI’s plan for the eastern concession is partially completed; it proposes to pilot the construction of small-scale self-standing systems for the combined collection of sewage and stormwater runoff in clearly defined densely populated areas. This plan forms the current MTSP project supported by the Bank. MWSI’s plan for the western concession will be completed in December 2005, and will be the subject of a new Bank project in FY06: Private Sector Support to MWSS Financial Rehabilitation.
