The Queanbeyan Sewage Treatment Plant (STP), constructed in the mid-1930s, treats sewage from Queanbeyan prior to discharge into the Molonglo River. Council has upgraded the STP on a number of occasions, with the latest upgrade being in the mid-1980s. While maintenance works are regularly undertaken on the STP, the plant is no longer fit-for-purpose. A significant works program is required to address issues including structural failure, equipment obsolescence, maintenance issues and work health and safety issues, as well as bring the treatment process in line with modern practices.
We are planning to upgrade this vital infrastructure from its current design capacity of 40,000 equivalent persons (EP) to cater for 60,000 EP. Planning for the project is well advanced, with master planning complete and the concept design being finalised.
