Royal Environmental Systems And Water Tectonics Design State-Of-The-Art Stormwater Treatment System

McRedmond Regional Water Quality Facility

Challenge
Located 20 miles east of Seattle, Washington, Redmond is home to 50,000 residents and many high-tech and biomedical companies, including Microsoft. Redmond's downtown drainage area is dominated by commercial, industrial and roadway areas, with typical surface pavement contaminants such as metals, nutrients and sediments.

Redmond's stormwater flows into the Sammamish River and Lake Sammamish, important waterbodies for rearing and migrating salmon species. To help prevent stormwater runoff from harming these waterways, the City of Redmond developed stringent stormwater regulations and sought a permanent stormwater treatment system that exceeded existing environmental guidelines.
