Sewer Reticulation
Sewage is collected and transferred to the pump stations and Waste Water Treatment Plant via a gravity reticulation network.
The network consists of approximately 190km of sewer main ranging from 150mm to 600mm diameter. Construction of the gravity network began in 1915, with much of the original pipework still in service. Some of the earlier pipes are in poor condition and cause operational problems. A variety of materials have been used in construction of the network including concrete, vitrified clay, asbestos cement, hobas, PVC and polyethylene.
During wet weather significantly increased flows are experienced at the Waste Water Teatment Plant. This can be attributed to the poor condition of some existing pipes, which are subject to infiltration from the surrounding ground during prolonged rainfall. Council continues an annual replacement program using trenchless techniques including relining and pipe bursting. This program is onoing to help maintain and improve the sewer reticulation network.
