TasWater’s $33 million Longford Sewage Treatment Plant (STP) upgrade is nearly complete, with the state-of-the-art plant becoming fully operational in stages as sections are brought on-line.

TasWater Project Manager, Catherine Thomas, said as part of the project’s advancement,  transferring waste to the plant for treatment has begun.

“Town sewage is already being treated through the new plant,” Ms Thomas said.

“Now, we will start transferring waste from the JBS Abattoir to the new plant, which is expected to start on Friday 12 November 2021.

“Following this transfer, the main lagoon will be emptied and cleaned in preparation for its conversion into temporary storage for treated waste.

“These works may result in some noticeable odour in the area surrounding the STP until the transfer is fully completed.

“This is scheduled to commence on Monday 22 November 2021 and may take several weeks depending on the amount of material to be removed.”

TasWater will monitor odour to help prevent it from impacting the community, if it arises during this stage.

“One of the benefits of the new plant is that it includes collection and treatment of odour, something that was not possible with the old plant,” Ms Thomas said.

“This means that once the new plant is fully operational it will lead to a reduction of odour on site.”

The new STP will use a technology called Nereda®, which will enable TasWater to process sewage more efficiently compared with more conventional treatment methods.

“It will be a more environmentally sustainable plant and future proof Longford’s sewage treatment for years to come,” Ms Thomas said.

These upgrades are being delivered by the TasWater Capital Delivery Office (CDO) and are part of TasWater’s investments in new and improved infrastructure across Tasmania.
