Septic tanks and desludging
To help keep things flowing smoothly, GMB Water runs a regular Septic Tank Desludge Program for all properties connected to our Community Wastewater Management System (CWMS). This scheduled maintenance helps prevent blockages and avoid costly plumbing issues—both on your property and across the broader wastewater network.

Projects and works
Central Sector Sewer Trunk Main
GMB Water continues work on the construction of new sewer trunk mains in various locations throughout Mount Barker and surrounding areas. The construction of four new or upgraded wastewater trunk sewers in the Mount Barker area is required so the collection network has the required capacity to cater for growth. The trunk sewers are 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 followed by the CBD sewer trunk mains (currently under construction), and then the Central and Eastern Stage Two projects.
