SunWater announced on Thursday the multi-million dollar repair works for the Boondooma Dam spillway are now complete.

The works – originally estimated to cost $50 million – repaired damage sustained during the 2011 and 2013 floods.

A SunWater spokesperson said the repairs should help to minimise the impact future extreme weather may have on the dam structure and surrounding communities.

SunWater CEO Nicole Hollows said the repair work ensured the dam spillway,  which aims to safely divert excess water downstream to the Boyne River, would continue to function as designed.

“The project to repair Boondooma Dam’s spillway initially started in 2011 following the first flood event,” Ms Hollows said.

“After further damage was sustained in 2013, SunWater worked extensively with our customers and stakeholders to return the spillway to pre-flood levels of functionality.

“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.

“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 (a structure at the top of the spillway which calms water flow) with corrosion protected anchoring.
