SMEC, in an alliance with Seymour Whyte and Toowoomba Regional Council (TRC) will deliver the Cressbrook Dam Safety Improvement Project.

The project aims to allow the Cressbrook Dam to safely handle surplus water during intense rainfall, raising the dam crest height, whilst also aligning the structure with current engineering design standards and safety regulations.

 

As a result, enhanced flood capacity and resilience will be delivered to the dam, whilst maintaining its current 81,900 ML drinking water storage capacity.

 

SMEC will commence the Detailed Design phase, encompassing the dam spillway widening, embankment increasement and design configuration of the plunge pool.

 

We are pleased to be working alongside our Alliance partners to help deliver resilient water infrastructure for the Toowoomba Region.The long-term viability of key assets like Cressbrook Dam are vital to regional communities and we look forward to bringing our expertise to the project.
———— Kate Drews, SMEC ANZ CEO (Acting)

The design and construction will include the provision of allowances for natural fish migration and integrate circular economy principles including the reuse of rock.

SMEC’s Design Manager for the project, Louiza Van Vuuren stated, “It is an honour to be part of the team to deliver the Cressbrook Dam Safety Improvement Project.”

“We are looking forward to working with Toowoomba Regional Council and Seymour Whyte to deliver technical excellence on Council’s biggest project to date.”

“Our team is committed and excited to successfully deliver the project, which will extend the safe operation of this critical water infrastructure asset.”

The improvements are required to meet acceptable flood capacity modelling guidelines revised by the Australian National Committee on Large Dams (ANCOLD).

Construction is expected to start in 2024 with key works expected to be completed in late 2025. Some ancillary works may be required to the end of 2026.
