The Redcliffe Sewage Treatment Plant (STP), located in the suburb of Clontarf on the Redcliffe Peninsula, services residents and businesses from the suburbs of Rothwell, Kippa-Ring, Redcliffe, Clontarf, Scarborough, Margate and Woody Point.
Unitywater commenced operation of the STP on 4 June 2012. Soon afterwards we began remediation works at the facility in order to provide a safe working environment for the operators and to ensure long term reliability of equipment.
Looking beyond the initial remediation works, Unitywater’s Board approved plans to rehabilitate the STP under a Design, Build, Operate and Maintain model.
After the completion of a tendering process and evaluation period, in January 2015 Unitywater appointed TRILITY Pty Ltd to undertake the rehabilitation of the Redcliffe STP and to operate it on Unitywater’s behalf until 2022.
TRILITY is an established industry leader, solely dedicated in the delivery of water, wastewater and reuse solutions across Australia’s municipal and industrial sectors.
Objectives of the Redcliffe STP rehabilitation
The proposed rehabilitation of the Redcliffe STP aims to:
- renew assets to ensure the STP has the capacity, serviceability and performance to meet the needs of the Redcliffe Peninsula communities
- operate the STP to ensure we continue to meet our environmental obligations
- maintain treatment capacity equivalent to a community of 70,000 people until 2026.
While TRILITY Pty Ltd will operate and maintain the STP, Unitywater remains the holder of the Environmental Licence.
