At its core, GMB Water has been established pursuant to Section 42 of the Local Government Act 1999 (SA) to oversee and operate Mount Barker District Council’s expanding wastewater and recycled water services.
The establishment of the Subsidiary enabled the Council to recruit specialist expertise and capability to effectively and efficiently oversee and manage the increasing scale and complexity of the operation and delivery of wastewater and recycled water services.
The Board of Directors, appointed by Council, are responsible for setting overall strategy, policy and direction to take forward to operation and expansion of the Council’s wastewater and recycled water services. The Board meets at least every three months.
