Central Sector Sewer Trunk Main
On this page
The Central Sewer Trunk Main project will enhance the wastewater network along the rail corridor between Hampden Road through to Heysen Boulevard. The project involves the installation of approximately 2.4km of new sewer pipe, along with maintenance and flushing points for future connections. Ageing pipes along the route will also be replaced, ensuring wastewater infrastructure can meet current and future demands while safeguarding the environment. The Central Project is expected to finish by the end of March 2026.
The construction of four new or upgraded wastewater trunk sewers in the Mount Barker area is underway to ensure the collection network has the required capacity to cater for growth. This Program of Works is required to enable the provision of an essential public health service and to satisfy legal obligations entered into with a number of developers in the Mount Barker growth area to supply development sites with a sewer service. The Nairne trunk sewer, completed in April 2025, was the first of the sewer trunk main projects to be delivered under this Program, followed by the CBD sewer trunk mains (nearing completion), and then the Central and Eastern Stage Two projects.
Project benefits
The Sewer Trunk Main Program of Works brings multiple benefits to the Mount Barker community, including:

- Improved Environmental Protection: Minimised risks of leaks and overflows, protecting local waterways and natural areas.
- Reduced Service Disruptions: Modern infrastructure requiring less maintenance, leading to fewer interruptions for households and businesses.

You may notice construction related activity in your area. Workers, machinery and vehicles will be active in the area, and temporary road, pedestrian crossing and/or footpath closures with detours may be in place at times. Traffic speed restrictions may also be implemented where required. Some properties may have short-term restricted driveway or parking access changes. Affected residents will be contacted directly and in advance.
Some noise can be expected while works are completed. Pumps or vacuum trucks may be louder at times, depending on weather and ground conditions. Measures like street sweepers, mats and ballasts will be implemented where required to help reduce mud on roads and impacts to softer surfaces. Some properties may have short-term restricted driveway or parking access changes. Affected residents will be contacted directly and in advance. Tree trimming will only occur if required and always undertaken with Council Arborist oversight. Dewatering pumps may run overnight during wet weather to help keep the project on schedule and reduce how long the community is affected by works. These will operate on low settings to reduce noise.
Street sweepers, mats and ballasts will be implemented where required to help reduce mud on roads and impacts to softer surfaces, and watercarts will be deployed for dust suppression during drier periods, when required.
