Work on the $22 million West Byron Bay sewage treatment plant upgrade is to start this month.
As part of the project, a pipeline will be constructed to carry all sewage from South Byron Bay and Suffolk Park to the upgraded plant.
That work will be carried out in four stages with the first stage from the West Byron Bay plant to Belongil Creek.
The other stages are from Belongil Creek to the railway crossing, South Byron Bay treatment plant to the Old Bangalow Road turn-off and Bangalow Road to Jonson Street.
The final stage is planned to start in March and be completed in June next year.
Byron Council's general manager, Pamela Westing, said construction work would be confined to the two treatment plant sites during the Christmas-New Year period to minimise the impact on residents, business and tourists.
