Full Description

The City of Portland's Bureau of Water Works (Bureau) has supplied domestic waterto Portland-area residents since 1895. It is the largest supplier of domesticwater in Oregon and supplies both retail and wholesale water to nearly 840,000people. The Bureau faces a wide variety of challenges and uncertainties as itenters the new millennium. These uncertainties arise from three principalsources: current federal regulatory requirements and potential future changesthat affect water quality standards, treatment, and the Endangered Species Act(ESA); decisions by current and potential wholesale customers about whether toobtain supply from Portland or elsewhere; and, decisions about where to obtainadditional supply in the future and whether groundwater will be a basic componentof the future supply or will be reserved only for emergencies. While the RegionalWater Supply Plan (RWSP), completed in 1996, has provided the Bureau with aregional vision for the supply system, it did not specify how individual watersuppliers would implement that vision or how transmission and major storage wouldbe handled. In addition, the RWSP did not investigate what each regional supplierwould need to do in order to maintain its existing system at a high level ofreliability. With the RWSP as its reference, the Bureau undertook its owninfrastructure master planning effort to develop a long-range, integratedapproach to resolving the key issues that will materially affect the system overthe next 50 years. This paper describes the Infrastructure Master Plan (IMP)which explores these challenges and charts alternative courses to meeting themduring the next 50 years. The IMP is also intended to be used by the Water Bureauto guide its Capital Improvement Program (CIP) towards meeting the water system'sshort-term needs over the CIP's 10-year term by both identifying new projects andconfirming the need for other previously identified projects. Includes 4 references, tables, figures.
