Project Update: New wastewater treatment plant opened

The new Point Lookout wastewater treatment plant has been officially opened ahead of the busy summer holiday period.

A joint initiative of Redland City Council and the State Government, and designed to serve the needs of the township for the next 30 years, the new plant is a crucial piece of infrastructure that will ensure safe, reliable and environmentally-friendly wastewater treatment for Point Lookout.

The $13.5 million, state-of-the-art facility has replaced an outdated plant built more than 30 years ago, increasing its processing capacity to meet future peak demands while reducing odour and adhering to strict environmental conditions.

Designed to cater for current and projected seasonal demands, it has capacity to treat 1600 kilolitres of wastewater a day, more than twice the current peak flow. The sewerage network will now be extended to more properties currently using septic systems in the township.

Featuring advanced membrane bioreactor technology, the new plant produces high quality effluent through ultra-fine screening, denitrification, chemical phosphorous removal, membrane treatment and disinfection, which is essential to protect the unique island environment.

Odour control was a key focus of its design, with a number of controls installed to significantly reduce emissions. Wastewater is treated through a three-stage process at the new plant to ensure it meets very strict environmental licence conditions set by the Department of Environment and Heritage Protection. This process is monitored through the Healthy Waterways initiative in south-east Queensland to ensure minimal impact on water quality and aquatic life, protecting the natural beauty of North Stradbroke Island.

Detailed design of the sewerage network extension is already underway, with a $5 million, three-year construction program expected to commence early in the 2017-18 financial year. Community engagement activities are planned for early 2017 with the goal of providing the most efficient design while minimising impact on the community.

The new facility was jointly opened by Redland City Mayor Karen Williams and Mr Glenn Butcher MP, Assistant Minister for Local Government and Infrastructure on Friday 25 November. The Mayor and Assistant Minister were joined by Brad Taylor (Redland City Council), Gary Souter (Redland City Council), Mike Basterfield (Downer), Jim Pruss (Seqwater) and Andrew Morrison (Downer) for the official opening.
