One of the oldest pipelines in the SEQ Water Grid will soon be replaced to improve the reliability of drinking water supply to more than 50,000 consumers in Brisbane’s north-west.
Now at the age of 75, the underground pipeline along Wardell Street, between Ashgrove and Enoggera, is nearing the end of its life and is ready for retirement.
Seqwater Chief Executive Officer Peter Dennis said specialist consultants had been engaged to investigate options for addressing the condition of the pipeline.
“The pipeline is an important part of the SEQ Water Grid, directly supplying Ashgrove and Mitchelton, while also supporting the reliability of supply to the northern suburbs of Brisbane,” Mr Dennis said.
“It was determined that the best solution to continue to provide a reliable water supply to the area was to construct two new sections of underground pipeline and decommission the old water pipeline.
“We then worked with other service providers and government agencies including Queensland Urban Utilities, the Department of Transport and Main Roads, Queensland Rail and Brisbane City Council, to select an optimal alignment that followed the road.”
The $4.2 million upgrade will consist of three stages and is expected to take about nine months to complete.
It will involve installing a new section of water pipeline in Ashgrove, starting at the end of Bridge Street, north-east of Frasers Bridge, and connecting to an existing pipeline near the corner of Victoria and Ashbourne Street.
The second section of pipeline will be laid between Lloyd Street, Alderley and Pickering Street, Enoggera.
Once the construction of both new pipeline sections is complete, the existing water pipeline along Wardell Street will be decommissioned.
Work in Ashgrove started today, with work in Alderley and Enoggera expected to start late August.
“Work will involve drilling under select roads and the railway line, as well as excavating in roads and road reserves,” Mr Dennis said.
Water supply in the area will not be affected by the project.
“While we’re laying the pipe there may be an increase in noise, dust and traffic in the local area. The project will comply with set requirements and will be managed to have minimal impact on the community.
“We appreciate the understanding and patience of locals during this work, which is vital to provide a reliable drinking water supply to more than 50,000 local consumers for many years to come.
