About the project
Over the next five years, Southern Rural Water is making a $30 million investment to complete piping and modernisation of the Werribee Irrigation District so that it is more efficient, reliable and resilient to a drier climate.
In 2016, Southern Rural Water completed pipelining and upgrades to the 4/1 channel system in Werribee South which kicked off the modernisation of the district.
Pipelining the 4/1 system means that about a third of the district is piped. The project was completed ahead of schedule and under budget which means that the money can be used for the next phase of pipelining.
Where are we now?
SRW’s Werribee irrigation modernisation project has progressed well, with Stages 1 and 2 completed in 2017 and 2018 respectively. Stage 3 works were completed and have been operating since the end of September 2019.
Stage 1 involved construction of almost 3km of pipeline from the Main Channel starting at the freeway and progressing to the junction between Diggers Road and Aviation Road.
Stage 2 was one of the longest sections, with 9.3 km of pipeline laid from the end of the Stage 1 pipeline works. The Main Channel along Diggers Road to K Road and the 6/1 channel system along O’connors Road were replaced with new pipelines.
Stage 3 comprised an additional 10.4 km of new pipeline replacing the old channel on the same alignment.
The completion of Stage 3 in September 2019, means that the project has built more than 28km of pipeline, and 200 new customer outlets have been constructed.
The annual losses in those areas of the district were estimated to be 2,250ML annually. Avoiding these losses represents a significant efficiency improvement that has already contributed to a higher seasonal allocation to our Werribee customers.
The project team is working on the designs and plans for the remaining stages of the project. We have already completed survey work and used drones to document the existing condition and alignment of the irrigation assets.
