Septic tanks and desludging
The Septic Tank Desludge Program is the periodical cleaning or desludging of all septic tanks connected to GMB Water's Community Wastewater Management System (CWMS). This is essential to prevent plumbing maintenance costs associated with blocked drains, both on your property and to Council's infrastructure.

Projects and works
Central Sewer Trunk Main
GMB Water has commenced 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 to be delivered followed by the Mount Barker CBD (currently under construction), and then the Central and Eastern Stage Two projects.
