Carnation Treatment Plant

Plant dedication -- June 2, 2008

Carnation community members came together on June 2, 2008 to celebrate the completion of their new wastewater treatment plant – a facility that protects local water quality and helps ensure future growth in the region.

“Replacing old, failing septic systems with a new, state-of-the-art treatment plant will protect this beautiful Snoqualmie River and all the creatures that love and depend on it,” said King County Executive Ron Sims at the dedication ceremony. “Carnation’s future environmental and economic goals are ensured, thanks to this facility.”

The plant treats wastewater to such a degree that highly treated reclaimed water will be used to enhance a wetland at Chinook Bend Natural Area, a mile and a half north of the Carnation plant.  In addition to the reclaimed water, the plant has been designed with numerous “green” features that minimize impacts on the environment, conserve resources and maximize energy efficiency.  For example, regionally available materials and materials with recycled content were used during plant construction, and construction waste was recycled whenever possible. Energy and water efficient equipment was installed throughout the plant, and the building was designed to take advantage of natural light for indoor spaces.
