Bromelton Trunk Water Main

Queensland Urban Utilties

Bromelton, Queensland, Australia

To support expected regional growth, Diona were engaged to install approximately 6.5km of trunk water main, from the rear of the Helen Street Water Treatment Plant, extending west towards Boonah-Beaudesert Road, Bromelton. The 15,000ha site – located in the Scenic Rim Regional Council area, 6km west of Beaudesert and 75km south of Brisbane – was one of two industrial areas identified by the Queensland State Government in 2007 to provide jobs and infrastructure for future population growth. 

The Trunk main was designed, constructed and managed in accordance with ecologically sustainable development principles, including cleaner production, waste minimisation, energy efficiency and water conservation. The water supply and pressure will improve fire-fighting capacity. The majority of the alignment was constructed using open-trenching with some directional drill under the Logan River and a bore under Bromelton House Road. 

Challenges and highlights

The project presented a number of challenges, including open-trenching through sensitive Cultural Heritage Areas. Three culturally important areas existed along the route of the pipeline and more than 5,000 Aboriginal artefacts, some about 4,000 years old, including barbs and points were uncovered. Each artefact has been photographed, documented and returned to the Mununjali people.

Additionally, some vegetation clearing, including tree removal in accordance with council permits, was undertaken to allow excavation for the new main along Boonah-Beaudesert Road. A qualified arborist and fauna spotter was engaged to supervise the clearing.

This enabling infrastructure will lead to more job opportunities and support strong, connected communities within easy commuting distances.
