Work starts on Bonalbo water treatment plant
April 8, 2009
Construction works for the new water treatment plant to service the village of Bonalbo commenced on Monday 6 April, 2009.
A sod-turning ceremony was held at the Water Treatment Plant (WTP) site and was attended by C Ward Councillors Ernie Bennett, Tom Cooper and Lindsay Passfield, Council’s General Manager Arthur Piggott, Manager Asset Services Graham Kennett, as well as staff and students from Bonalbo Central School.
The construction of the new WTP represents the biggest investment in the Bonalbo Water Supply since its initial construction in 1966.
The construction of the water treatment plant and waste water sludge lagoons is the last part of the overall water supply augmentation which represents a total investment of around $1.6 million.
Other works completed in the lead-up to the start of construction of the new water treatment plant include:
- Internal roadworks and earthworks for the water treatment plant building
- Electricity supply upgrade and construction of communications conduits
- Extension of the sewerage system
- Installation of a dam destratification system
- Replacement of the Bonalbo reservoir roof and access provisions
- Commissioning of new groundwater bore source near Peacock Creek
- Upgrade of the Peacock Creek water extraction pumping station.
The construction of the WTP is funded 50% by Kyogle Council and 50% by the NSW State Government under the Country Towns Water Supply and Sewerage Program.
The WTP component is a design-and-construct contract. The head contractors are Water Systems Australia, who are based at the Gold Coast, with the major civil sub-contractor being All-Steel Garages and Sheds, based in Casino.
The new water treatment plant will treat water taken from the Petrochilos (Bonalbo) Dam.
The water treatment process consists of chemical dosing and mechanical flocculation tank up front, followed by a dissolved air flotation tank manufactured by AJM Environmental Services, then filtration through a gravity media filter.
The filtered water will then be chlorinated and fluoridated prior to being pumped to the Bonalbo reservoir for reticulation back to town.
The water treatment plant is expected to be commissioned in July 2009.
