Construction dewatering presents an interesting range of problems and issues with contamination and clogging. The Perth city project had mandatory raw water treatment before it was allowed back into a local stream and river. You can see the orange stains from the iron but the real issue was the carbonate build up in the pipes and sensors. Fortunately EZ ECO and Multikleen are an easy economical solution and a quick soak soon had the equipment fully operational.
