Client project
BHP – WTP Interim Storage Project
Overview
The project involved the install and commissioning of three new water tanks and ancillary equipment to the Newman Water Treatment Plant. The site was located on a sloped area adjacent to the existing plant which coincided with a large earthworks development to create a level pad for the additional tanks. Doolee undertook the civil aspects of this project working closely with Downer and BHP to complete this fast‑tracked project. The project started in February 2024 with completion expected in Q3 2024.
