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

Located 20 miles east of Seattle, WA, 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. To help prevent stormwater runoff from harming local waterways, the city developed stringent stormwater regulations and sought a permanent stormwater treatment system that exceeded existing environmental guidelines. Water Tectonics, in conjunction with Royal Environmental Systems, designed a system to remove total and dissolved metals, phosphorus, and suspended sediments. The end product is one of the first of its kind in the country and is being monitored as part of a long-term evaluation study.
