Spillway works complete at Boondooma Dam

Spillway works complete at Boondooma Dam

Works to repair Boondooma Dam spillway in the South Burnett region are complete, SunWater says.

The works repaired damage sustained during 2011 and 2013 flood events and will help minimise the impact f future extreme weather events.

Civil engineering firm Fulton Hogan was principal contractor for the project.

SunWater chief executive officer Nicole Hollows said the repair work ensured the dam spillway would continue to function as designed.

“Pleasingly throughout the project we were able to hire local labour and partner with local businesses to source construction materials and provide accommodation, bringing great economic benefits to the South Burnett region,” she said.

“It was a significant project delivered under budget at a cost substantially less than originally estimated after the flood impacts.”

Works included:

  • stabilisation of the spillway right wall
  • construction of a secondary Erosion Control Structure (ECS) 30 metres upstream of the existing ECS
  • passive anchors within the unlined spillway chute
  • capping of the dykes between the existing and new ECS
  • concrete lining of the spillway walls between the crest and ECS
  • strengthening of the existing ogee crest with corrosion protected anchoring.
