North Western Sewer – Emergency Relief Structure

This project involved the design and construction of an Emergency Relief Structure (ERS) for the North Western Sewer (NWS). Its function is to mitigate backing-up effects and stop uncontrolled sewage spills, give protection to homes in low lying areas from sewerage spills, and to protect the sewer network from overload or damage during periods of extremely high demand.
