CBD Sector Sewer Trunk Main

We’re pleased to share that this important infrastructure project reached Practical Completion on 22 October 2025, with all final works wrapped up in March 2026.

This new sewer trunk main has been built to support Littlehampton and a large part of Mount Barker for more than 100 years, helping to meet the needs of our growing community now and into the future. It will deliver better service reliability, lower ongoing maintenance costs, and significantly reduce the risk of sewer overflows, helping protect the local environment.

The project was delivered on time and within budget, despite challenging conditions including deep excavations, difficult ground, limited access in some areas, and varying weather. Importantly, it was completed with no injuries or major incidents, a strong outcome for a complex project.

Throughout construction, BMD Constructions made a conscious effort to support local businesses, and many team members are part of the local community.

Environmental and community improvements were also a key focus. Sections of the shared linear trail were upgraded, and while some unsuitable trees were removed, they have been replaced with around 600 new trees, far exceeding the number removed. These new plantings—located from behind Cornerstone College along the creek and reserves through to the Laratinga Water Recovery Plant—are being maintained under a two-year care program, with any losses to be replaced.

This project forms part of a broader program to strengthen the region’s wastewater network, ensuring it can support existing neighbourhoods and future development, while safeguarding the health of residents and the environment.
