Belconnen Trunk Sewer Upgrade Projects

Quick links

Icon Water is currently planning upgrades to the Belconnen trunk sewer. The Belconnen trunk sewer was built in the 1960s and is a critical part of the Belconnen sewerage network which serves Belconnen, Gungahlin and Hall. Icon Water is planning for the future of Belconnen and these projects are important to ensure we can continue to provide services for generations to come.

Why do we need to upgrade the sewer?

Like most of Australia’s capital cities, Canberra’s population is growing and this increases demand on our water and sewer infrastructure. Major development has recently occurred in the Gungahlin region, and planned development at the University of Canberra, the new suburb of Lawson and the CSIRO's Ginninderra Field Station, mean that the sewer is nearing capacity and needs to be upgraded to ensure it can continue to meet demand. 

During extreme wet weather events, rainwater and an already steady flow in the sewer can result in sewage escaping from the sewer pipes into Ginninderra Creek. Icon Water appreciates how valued the environment and waterways are and these projects will ensure that any risk of overflow into local waterways is significantly reduced.

In addition to improving capacity, the network also requires some extra ventilation and odour control units (OCU) to protect new and existing sewerage infrastructure and minimise impacts to the surrounding community. See our factsheet on the project need

Who is going to pay for the Belconnen trunk sewer upgrade projects?

Icon Water’s charges are regulated by the Independent Competition and Regulatory Commission (ICRC), which sets the prices for water and sewerage in the ACT. Every five years we prepare a submission detailing what the cost of operations will be for the next five years. The ICRC then sets the prices that Icon Water will charge to cover those costs. We have an obligation to deliver value to the community, and to ensure that our operations are prudent and efficient. In the last regulatory submission, we included the price of the Belconnen trunk sewer upgrade projects in our calculations, and the cost of this project has already been accounted for in the current water and sewerage pricing. 

The Belconnen trunk sewer upgrades will comprise of four projects over the next few years. They include:
