New water control structures have been completed at Oak Creek and Gras Innes as part of the $65 million Computer Aided River Management (CARM) Project.
AWMA worked with contractor GJ&KL Douglass on this project which aims to bring water savings and improved service to water users along the Murrumbidgee River. Two ULF undershot penstock gates were constructed from marine grade aluminium for the Oak Creek site. The gates were designed to withstand both on and off seating hydrostatic heads of 2.5m.
Gate operation is via manual or automated control. Automatic operation will be based on inputs from upstream and downstream level sensors. SCADA access will be available via State Water’s existing system with power available from solar panels installed adjacent to the site.
The Gras Innes site required a single ULF undershot penstock gate constructed from marine grade aluminium. The gate is manually operated and designed to withstand both on and off seating hydrostatic heads of 1.2m.
The Bundidgerry Creek is a tributary of the Murrumbidgee River, used as a conduit for delivery of irrigation water to the Murrumbidgee Irrigation Area. Oak Creek and Gras Innes are break outs from the Bundidgerry storage and are approximately 10 kilometres east of Narrandera, NSW.
