In September 2022, Veolia undertook a detailed condition assessment of a high risk trunk main in Echuca.These works were the final stage following of the pre-condition assessment of 9.5km trunk mains undertaken in 2021.The watermain was installed in 1941
The 2022 assessment included physical excavation of the water main at 4 site to allow actual measurement of the following parameters:
● pipe thickness
● pipe depth
● soil corrosivity
● electrical potential
Upon completion of the testing, of a cathodic protection sacrificial anode and test point was physically connected to the pipeline at each test site, to provide ongoing protection against corrosion
The study found the pipeline was in very good condition at all 4 sites
