The Northern Midlands Council has approved upgrade plans for a Longford sewage treatment plant aimed at reducing the impact of long-running odour issues.
TasWater awarded the design and construction contract to Aquatec Maxon in July after investigations by the body into the source of resident complaints, which surged in February.
An earlier investigation by the Environmental Protection Authority identified a number of sources including the nearby JBS meatworks, along with TasWater's sewage plant and pump station.
The council voted unanimously to approve upgrade work on the Bishopsbourne Road site at its meeting last week.

A report prepared by the council's senior planner noted the upgrade would achieve licence effluent emission limits and reduce the potential for odour emissions from the plant.
Announcing the works in July, TasWater project manager Rennie Brown said the new plant would feature an innovative design that was the "first of its kind" in the state.
This would include a two-stage odour control system to remove them "before air is extracted".
"This will help us meet our commitment to the community to reduce odours coming from the sewage treatment plant," Mr Brown said. "We have made significant improvements recently ... [but] some odour may be noticed at times until the new plant is commissioned."
