Bonalbo water treament complete

KYOGLE Council is proud to announce that construction and commissioning of the new water treatment plant to service the village of Bonalbo is now complete.

For the first time since the Bonalbo water supply was constructed in 1966, council is able to deliver water that consistently meets the Australian Drinking Water Guidelines.

The new Water Treatment Plant (WTP) represents the biggest investment in the Bonalbo Water Supply since its initial construction.

The WTP and associated waste water sludge lagoons are the last part of the overall water supply augmentation which represents a total investment of about $1.6m.

Other works completed as part of the water supply augmentation include:

  • Commissioning of new groundwater bore source near Peacock Creek;
  • Upgrade of the Peacock Creek water extraction pumping station;
  • Installation of a dam aeration/destratification system;
  • Dam safety works including spillway widening;
  • Replacement of the Bonalbo service reservoir roof and access provisions;
  • Sealing of internal road works around the water storage and WTP; and
  • Electricity and communications upgrade.

The water supply augmentation was funded half by Kyogle Council and half by the NSW State Government under the Country Towns Water Supply and Sewerage Program.

The new water treatment plant will treat water from the Petrochilos (Bonalbo) Dam.

The water treatment process consists of chemical dosing and flocculation, followed by a dissolved air flotation (DAF) tank, then filtration through a gravity sand filter.

The filtered water is then chlorinated and fluoridated prior to being pumped to the Bonalbo reservoir for reticulation back to the village.

The WTP design flow is 4.2 L/s, which will produce a peak 0.3ML/day.

The plant is equipped with state-of-the-art monitoring and control systems that allow automatic operation under the supervision of council's treatment plant operators.

There will be an official opening ceremony held on Monday, August 23, at 10am at the WTP site in High Street Bonalbo.
