The Utilities and Water and Waste Management series measures 1.6 cubic feet and dates from 1985 to 1990. This series primarily documents the decision-making process regarding Metro's 1990 conditional use application for the expansion of the West Point Sewage Treatment Facility, located in Discovery Park. A secondary treatment plant was part of a long-term goal of cleaning up the Puget Sound. Some records in the series address the issues of combined sewer overflow and secondary treatment prior to 1990. Alternatives and financial issues related to a treatment facility are addressed in reports and correspondence dating from 1986 to 1989, as well as consideration of Alki as a possible location for the treatment facility.

The records primarily document the decision to build a facility at West Point and the resistance by environmentalists and community members to the site. In 1990, the Hearing Examiner for the City held hearings in May regarding the West Point Metro permit and recommended granting the permits; City Council also held hearings and recommended the permits be granted. The parties involved in the hearings included the Department of Construction and Land Use, Metro, Magnolia Community Club, Friends of Discovery Park, and Puget Sound Water Quality Defense Fund, among others. Agendas and transcripts of the hearings are included in the records. Issues discussed in hearings include environmental and economic issues, odor and noise control, traffic and visual mitigation. Correspondents include Robert Kildall, R. J. Brooks, and Shary Flennikan, among others.
