Mole Creek water supply upgrades

The Mole Creek township, together with customer connections along the supply main, is currently supplied with raw water from Mole Creek weir.

There is no chemical treatment or disinfection currently provided to the raw water. The Mole Creek township has been on a ‘Boil Water’ notice for a number of years.

The new Mole Creek water treatment plant (WTP), is being built downstream of the existing water intake weir south west of Mole Creek township.

The Mole Creek township, together with customer connections along the supply main, is currently supplied with raw water from Mole Creek weir.

There is no chemical treatment or disinfection currently provided to the raw water. The Mole Creek township has been on a ‘Boil Water’ notice for a number of years.

The new Mole Creek water treatment plant (WTP), is being built downstream of the existing water intake weir south west of Mole Creek township. This new WTP will have a back-up power source on site, ensuring water supply continues in the event of local emergencies such as power outages or a bushfire.

Full treatment will enable TasWater to supply water to customers which complies with Australian Drinking Water Guidelines (ADWG) and address TasWater’s non-compliance with the Public Health Act 1997 (and ADWG), in accordance with its Water Quality Policy.

The new WTP will be equipped with ultraviolet and chlorine systems for disinfection. By combining both these technologies, the reliance on chlorine for disinfection can be reduced.

Laurie Curran Water was contracted to build the WTP and is at the stage where the building structure is complete with wiring, fittings and flooring being finalised.

Installation of mechanical equipment and pipework within the building is 75% complete and external infrastructure construction is underway.

As part of the upgrade to the Mole Creek water supply system, investigations of the current reticulation network are being carried out. Ground-penetrating radar is being used to identify any unknown water connections and to locate breaks in the system.

These investigations will inform future decisions regarding the ageing water trunk main and ensure services within the network are maintained once the water treatment plant is commissioned.

  • What is the currant status of the Mole Creek water supply upgrade- it has been 9 months surely SOMETHING must have been happening

    metalastic asked about 1 year ago

    Thank you for your enquiry.

    The Mole Creek Water Treatment Plant (WTP) construction is well under way and is scheduled to be completed by the end of October 2016. The building construction and internal fitout has been completed and the installation of mechanical equipment and pipework is nearing completion.

    The installation of the electrical connections and control systems has started and is progressing well. Unfortunately the adverse weather conditions over the last few weeks have caused some minor delays which are unavoidable.

    As part of the upgrade to the Mole Creek water supply system, investigations of the current reticulation network are being carried out. Work is underway using ground-penetrating radar to identify unknown water connections and identify any breaks or leaks in the system.

    These investigations will inform future decisions regarding the ageing water trunk main and ensure services within the network are maintained once the water treatment plant is commissioned.

    When tests prove that the water from the Mole Creek WTP conforms to Australian Drinking Water Guidelines (ADWG), TasWater can then apply to the Department of Health and Human Services (DHHS) for the existing boil water alert at Mole Creek to be permanently lifted.

    TasWater will work closely with Meander Valley Council and will notify customers in writing when the testing program has been completed and DHHS has lifted the boil water alert.
