Inverell Sewerage Treatment Plant Rehabilitation

PROJECT UPDATE – 19 November 2018

The two aeration tanks at the Inverell Sewage Treatment Plant, which have been in continuous operation for over 30 years, require major repairs to the floors and walls.

As the repairs require each of the tanks to be taken “off-line” while the work is completed and there is not sufficient capacity to operate with only one tank in service, Council has constructed another aeration tank to operate on a temporary basis. This temporary tank will form the basis for a permanent capacity upgrade in the future if this becomes necessary.

Eire Constructions Pty Ltd of Wauchope NSW was awarded the contract in the amount of $1,919,997.to construct the new aeration tank, with works completed in September 2017.

The next phase of the Inverell sewerage treatment plant renewal and upgrade project involving the major repairs to the floor and walls of the two aeration tanks and connection to the telemetry system is underway and will continue through to July 2020.

Council was successful in receiving financial assistance from the NSW Government towards the $2,860,000 project by way of a low-interest subsidy of 3% towards a loan of $2,000,000 over 10 years to undertake the construction works, representing a saving of $357,000 for ratepayers.
