Seqwater will be conducting routine cathodic testing across the state, as well as a planned burn and operational release at Wivenhoe Dam.

Cathodic testing and maintenance will take place over the next few months on above ground infrastructure that is designed to protect water pipelines against corrosion.

Contractors will be accessing pipeline easements along roadways and footpaths, as well as within parks and some private properties across greater Brisbane.

Work will be conducted throughout June, July and August between 7am and 5pm, Monday to Friday.

Planned burn

The planned burn will be conducted by Seqwater near Leslie Harrison Dam in a section of road reserve along Mt Gravatt-Capalaba Road, Burbank.

The burn will take about three to four days to complete.

As a landholder and statutory authority, Seqwater has a responsibility to protect bulk water infrastructure and to address fire management on its land.

Seqwater is conducting the burn in consultation with the Department of Transport and Main Roads and Queensland Fire and Emergency Services.

Traffic management will be in place along a section of Mt Gravatt-Capalaba Road (south of Brightview Street) to ensure access for motorists.

Operational release

Seqwater advises that a radial gate will be used to maintain normal water releases from Wivenhoe Dam for approximately two weeks.

Seqwater will begin by undertaking maintenance of the outlet works at Wivenhoe Dam. To facilitate this work, the outlet works and hydro-station will be taken off-line during business hours, and one radial gate will be opened to continue operational releases during daylight hours.

The releases are required to maintain supply, during the day, to downstream customers and meet environmental flow requirements. The hydro will be operated overnight to meet the water supply needs of the Mount Crosby Water Treatment Plants.

The change in mechanism is not expected to impact local communities and residents downstream of Wivenhoe Dam, as daily release volumes should not change from what is currently being released.

Any significant changes will be communicated on Seqwater’s website.
