McLaren Street Mount Barker upgrade

GMB Water has successfully completed the McLaren Street Gravity Sewer Mains Upgrade, delivering critical improvements to wastewater infrastructure in the Mount Barker CBD.

The project replaced ageing sewer mains with upgraded DN150 infrastructure, increasing capacity and improving reliability for residents and local businesses. These works reduce the risk of service interruptions and sewer overflows, supporting a safer and more consistent day-to-day service.

Environmental outcomes have also been strengthened, with the upgraded network reducing the likelihood of leaks into surrounding waterways, including the Mount Barker Creek catchment, helping protect the local environment. 

The new infrastructure future‑proofs the area by supporting growing demand and enabling the transition to a full sewer network across the CBD. This ensures long-term value for the community while improving asset performance and maintenance access. 

The project was delivered safely in a complex live environment, maintaining access to residents, businesses, emergency services, and an aged care facility throughout construction. Strong safety management and planning enabled successful delivery with minimal disruption to the community. 

Local contractors and suppliers played a key role in delivery, contributing to the regional economy and supporting local jobs.

GMB Water acknowledges the efforts of Fleurieu Civil, project teams, stakeholders, and the community for their cooperation and patience during the works.
