ABSTRACT

In response to its obligations under the SDWA and ADWG, Goulburn Valley Water (GVW) adopted specific turbidity targets for potable water and carried out a risk assessment of water supplies to the communities within its service area. Six small towns utilising only settling dams and disinfection prior to customer supply were identified as having water quality risks. GVW determined that membrane filtration was the appropriate treatment option to minimise those risks. A project was initiated to select the membrane filtration process that would be most suitable for all six small towns and to construct the initial membrane filtration plant at Girgarre. Girgarre is a small town ~40 km west of Shepparton with raw water supplied from the Goulburn Murray Water channel system. This paper describes the process undertaken by the team comprising GVW, the consulting engineer, Parsons Brinckerhoff Australia (PB) and the contractor, Haulton Water Services (HWS) to successfully complete this important project. The key issues covered include the drivers for the project, a review of the various membrane filtration technologies, the selection process used to determine which treatment process to use and a report on the on-going performance of the plant.
