New documents released by Toowoomba Regional Council have revealed more details on how the Greenmount Water Treatment Plant will look and how it will function.
Toowoomba Regional Council (TRC) has submitted a material change of use development application to itself in anticipation of the plant’s construction, expected to start this year and be completed by early 2027.
Once constructed, the plant will supply potable water for the townships of Greenmount, Nobby, Cambooya and Clifton, dubbed the ‘Four Communities’.
The plant is set to be built 13 Haldon Street, Greenmount, a 1.86 hectare vacant site owned by TRC. Greenmount State School borders this site to the west.
A planning report submitted as part of the application states that the proposed Water Treatment Plant (WTP) will comprise a conventional treatment plant with a capacity to treat three megalitres (three million litres) of raw water per day.
“The site is strategically located adjacent to the existing Haldon Street water reservoir to the north-east of the proposed development,” the report says.
“The Water Treatment Plant will be predominately located towards the Haldon Street frontage of the site, with exception to a raw water storage tank located at the rear of the site.
“The facility will include an administration/switchroom/wetlab building (administration building), dosing and storage facilities, and treatment plant components including holding tanks, raw water tank and an operating and emergency lagoon.
“The water treatment plant will be operated remotely for 24 hours a day, 7 days a week, with one operator visit daily during weekdays.”
In total, the development will cover about 13 per cent of the entire site.
Access will be provided via a new crossover to Haldon Street and four car parking spaces are proposed adjacent to the administration and switchroom/wetlab building.
The planning report states that a Traffic Impact Assessment is currently being prepared for the proposed development and will be lodged with Council on completion.
“Following completion of the treatment process, the treated water will be pumped to the adjacent Haldon Street reservoir before being gravity fed to the Cambooya, Greenmount, Nobby and Clifton communities,” the report says.
“It is noted that the existing Haldon Street reservoir has sufficient existing capacity to service these communities.”
It has yet been decided if fluoridation will be conducted at the plant.
The Queensland Government is providing $15 million over four years for the Four Communities Water Supply Project.
Also submitted as part of the application is the Greenmount Water Treatment Plant Preferred Option Report.
