Miller Creek Plant
Miller Creek Plant has the same capabilities as Salmon Creek. In addition, it's home to our Salmon Hatchery. 1015 SW 174TH PL Normandy Park, WA 98166-3465 Treatment Plant: 206-244-2202 
In 1965 construction of the most advanced primary treatment facilities of the time began at Miller Creek (Map). Upon the start of operations in 1967, the combined Miller Creek and Salmon Creek plants were treating over 4 million gallons of sewage a day.
The primary treatment process we were so proud of in 1967 is still the most efficient of its kind. Yet it removes only the floatable and sedimentary elements found in sewage, leaving many pollutants to be released into Puget Sound. Miller Creek was upgraded in 1972 with the provision of chlorine contact chambers while still providing primary treatment. In 1985 design began on a secondary treatment upgrade, which became operational in 1988. Secondary treatment removes at least 85% of the organic material, and nearly all of the toxics found in wastewater. We now have a primary and secondary treatment process at both of our treatment plants.The final phase at Miller Creek, odor scrubbing, became operational in November, 1991 for both the primary and secondary treatment processes. Domed covers and a network of fiberglass piping, combined with an "air scrubbing" process, have made the atmosphere at our plants virtually odor free. |
