Queensland Government-owned SunWater has committed $50.5 million to reinstate and repair the Boondooma Dam spillway in the South Burnett region.
Treasurer Curtis Pitt said the work would support about 120 full-time jobs for the region during construction.
“These works are essential to ensure the ongoing supply of water needed to power the Tarong Power Station,” Mr Pitt said.
“Restoring Boondooma Dam is also critical to ensure a secure supply for its many irrigation, agricultural and domestic customers.
“The project will include stabilising the dam wall, constructing a new erosion control structure, additional defensive anchors and wall protection.
“Onsite works are expected to commence in late 2016 during the wet season and be delivered by the end of 2017.”
Built in 1982, Boondooma Dam is located on the Boyne River and has a capacity of more than 204,200 ML.
It supplies between 50 million and 80 million litres of water to Tarong Power Station every day.
Of the dam’s yield capacity, three quarters is allocated to the power station, and the remainder is for irrigation customers downstream of the junction with the Burnett River at Munduberra.
SunWater is the largest owner of water supply infrastructure in Queensland and is a significant contributor to the rural, industrial, energy, mining and urban development of the state.
