The Geelong Waterworks and Sewerage Trust was constituted under the Geelong Municipal Water Act 1907, with it then being reconstituted under the Geelong Waterworks and Sewerage Act 1909. Its function was to ensure the supply of water and the provision of sewerage services in the Geelong region. This Trust became part of the Geelong and District Water Board under the Water and Sewerage Authorities (Restructuring) Act 1983. From 1995, water and sewerage for this region has been under the control of the Barwon Region Water Authority.
