City Water (previously Redland Water) builds and maintains infrastructure for transporting water and wastewater around the Redlands. Some of our recently completed projects include:
Thorneside wastewater treatment plant
Thorneside wastewater treatment plant and its connecting sewerage network have been successfully upgraded to ensure the system meets expected service standards while minimising ongoing maintenance costs. The project was a joint initiative of Redland City Council and the State Government who invested $2.7 million to replace old and ineffective equipment to reduce odour emissions for local residents and also assist with the upgrade of sewerage pump station 35, Wellington Point.
The State Government generously contributed 56 per cent of the project costs. The upgrade includes a new inlet structure designed with the latest screening and grit removal technology, an emergency overflow system to protect the plant from high stormwater inflows, and an upgrade of the odour control system.
Works were constructed by Ipswich based contractor Aquatec Maxcon who are leading providers in water and wastewater treatment processes. They have successfully utilised their own innovative self-cleaning band screens as part of the upgrade.
It is expected that the new works will greatly minimise un-biodegradable solids entering Tingalpa Creek and Moreton Bay. The project was commissioned in August 2017 and is performing to its design expectations.
Pump station 35 upgrade
As part of the Thorneside wastewater treatment plant upgrade, Redland City Council also replaced sewerage pump station 35.
Sewerage pump station 35 is located at 347 Birkdale Road, Wellington Point and is part of the Thorneside wastewater treatment plant catchment. The station was built in 1986 to cater for 7000 residents. Receiving wastewater from more than 10 pumping stations in Thorneside, Wellington Point and Ormiston, the station had reached capacity and needed to be upgraded to accomodate the growing population.
The new station is designed to service 23,000 residents, which equates to the ultimate growth of the upstream catchment. It is expected that there will be virtually no flow interruptions at the new pumping station because it utilises contemporary non-clogging pumps, as well as backup power supply which will minimise the risk of any sewage overflows.
The project included a new wet well and valve pit, new 375mm diameter pressure main, activated carbon odour control, switchboard replacement, installation of a new generator, flow meters, level transmitter, removal of the existing dosing building, and construction of a 600m rising main to connect the pump station to the intersection of Badgen Road.
Given its close proximity to the wetland, the design ensures minimal impact on the environment. The alignment to the sewer pressure main has been provided by the Department of Transport and Main Roads and allows for the future widening of Birkdale Road.
The project was successfully completed in September 2018.
Point Lookout wastewater treatment plant and network upgrade
In November 2016 Redland City Council officially opened its $15 million, state-of-the-art wastewater treatment plant at Point Lookout, North Stradbroke Island. The project was a joint initiative of Redland City Council and the State Government who contributed over $3.38 million to improve the facility for local residents.
Project benefits Prior to its upgrade in 2016, wastewater produced in the Point Lookout catchment was treated by three standalone activated sludge plants with a combined service capacity of 1750 persons, or approximately 400 kilolitres per day. The new plant is designed to service up to 7600 residents in the Point Lookout catchment area including the fluctuation of visitors during peak holiday periods. The plant can treat up to 1600 kilolitres of wastewater per day, almost three times its previous capacity. Membrane bioreactor (MBR) technology processes wastewater via ultra-fine screening and grit removal, nitrification and dentrification, biological and chemical phosphorus removal, and ultra-filtration membrane treatment, producing a very high quality effluent.
The plant uses membrane bioreactor (MBR) technology, proven technology that will provide the best outcome for residents and the environment in terms of the quality of effluent treatment, the operation and maintenance of the small footprint plant and minimal odour for neighbouring residences. Odour control equipment was also installed at the plant to ensure no odour nuisances occurred.

Dunwich sewerage upgrade
In August 2014, Redland City Council began a project to extend sewerage services to more than 200 properties at Dunwich, North Stradbroke Island. Following delays caused by buried debris, bedrock and poor weather, the project was completed in October 2015, with property owners having three years to connect to the sewerage system. Properties in the following streets are now able to connect to the sewerage network:
- Fraser Street, Oxley Parade, Mermaid Street, Mitchell Crescent, Mallon Street and Shephards Lane.
- Sections of Barton Street, Bingle Road, Cunningham Street, Dickson Way, Finnegan Street, Guy Crescent, Parsons Street, Pamphlet Street, Rous Street, Sally Street, Stradbroke Place and Welsby Street.
Sewer access charges will apply from 1 October 2015 to all allotments captured in this project, whether the property has been connected or not.
