The concept design, expected to take about six months to complete, would establish the civil, electrical and mechanical requirements of the project.

MidCoast Council infrastructure and engineering services director, Rob Scott, said the project had been planned for a number of years and it was now time to move forward with it.

"In its current capacity, the Hawks Nest Sewage Treatment Plant is working hard to process the volume of sewage coming into the plant, especially during peak holiday periods," he said.

"With Hawks Nest's population expected to grow, this project will ensure the plant is equipped to meet the community's wastewater needs well into the future."

The project will see two clarification tanks and a new sludge lagoon constructed at the facility, while the existing aeration tanks will undergo significant modifications to ensure they can process larger volumes of sewage.

The ultraviolet disinfection and chemical dosing systems at the plant will also be upgraded.

"Not only will this project ensure the plant can cater for the community's growing needs, it will lead to better environmental outcomes, as the effluent coming out of the plant will ultimately be treated to a higher standard," Mr Scott said.

"Concept design is a vital stage in the project and will allow us to progress to detailed design and then construction, with the project expected to be completed in 2023."
