This steel facility is 145 acres and operates as a scrap metal recycler and steel mill, discharging stormwater into the Willamette River. This river is an EPA Superfund Site, and as part of an agreement with the Oregon Department of Environmental Quality to implement an upland source control plan, the site owner agreed to install a treatment system to remove sediment, metals, and other contaminants. Clear Water designed and installed a permanent 3,600gpm chitosan enhanced sand filtration (CESF) system to treat turbidity, high pH, and other contaminants, and has been operating the system since installation. By installing a Clear Water system, the site owner has achieved a drastic 93% reduction in sediment, and addressed heavy metals. To date, the owner has been compliant with the Industrial Stormwater General Permit; discharging over 16 million gallons of treated effluent water below all benchmarks. Clear Water created and installed a custom online dashboard for the owner to monitor all parameters, generate trend lines, access reports, track weather, and interconnect with the Human-Machine Interface (HMI) through the Clear Water Client Portal on our website.
