By working with your environmental consultant, we’ll take a customized approach based on the scale of project and contamination level on your site to ensure you get the best solution.
The problem: A large development is under construction at an excavated site. Water collects in the work site which stalls progress until dewatering can be completed. The client wanted to discharge water into the storm drain that feeds into local streams which are a salmon habitat. Due to the high sediment levels in the water, this client required a treatment process to reduce TSS loading because of detrimental harm to aquatic life.
Solution: We designed and installed a physicochemical treatment to remove solids and produce clean effluent safe to discharge. Weekly site visits and regular testing from our team ensure the system is performant.
Coagulation, flocculation, settling tanks, sand filtration to capture remaining solids, and clean water can be discharged directly down the storm drain.
