The City of Seattle has utilized the design-build-operate contracting approach for
development of two major treatment facilities. As an alternative to the conventional public
works procurement process, Seattle has sought to create situations where integrated teams
of designers, constructors, and operators would innovate in order to provide the most reliable
and cost effective proposal for development of the projects, while maintaining public
ownership of the facilities. The two projects will provide 99% of the water to about 1.3 million
people in Seattle and the surrounding cities. The Tolt Treatment Facility is a 120 million
gallon per day (MGD) filtration and ozonation plant for treatment of Seattle's Tolt River
source of supply, which provides about a third of the water for Seattle and it's 26 regional
wholesale customers. The Tolt facility has been operational since early 2001. The Cedar
Treatment facility will be a 180 MGD ozonation and UV disinfection plant for treatment of the
Cedar source of supply, which provides about two-thirds of the water for the region. The
Cedar facility is scheduled to begin construction in spring of 2002, and be operational by late
2004. If operational today, the Cedar facility would be the world's largest UV drinking water
treatment facility. This paper discusses issues and options related to project definition, and
real project examples of risk allocation during implementation of these projects. Includes 2 references, figures.
