Douglas Water Treatment Plant Water Clarifiers

Investment$30 million
Goal4. A sustainable destination that embraces and participates in the arts, sports and events and recreational activities
Strategic PurposeTo enhance Townsville's long-term water security and increase capacity to produce clean, healthy drinking water for the city as its population grows.

Project Overview

Construction of two new water clarifiers at the Douglas Water Treatment Plant is well underway, enhancing the facility’s capacity to produce clean, healthy drinking water for the city.

The installation of the new clarifiers is a $30 million investment in the future and addresses the unexpected interruptions to water delivery experienced in late 2020 and early 2021. The project budget has increased in the 2022/2023 financial year from the initial $27.5 million, due to an increase in the project scope of works.

BMD Constructions has been awarded the contract to construct the new clarifiers, which supports around 40 jobs. 525 tonnes of reinforcing steel and 1,750 cubic metres of concrete has gone into the construction of the clarifiers, with the final concrete pour completed in September 2022.

Construction of the Module 3 Clarifier has progressed significantly, with lamellas, steel work and pipework now installed and hydrotesting complete. Electrical energisation, point to point testing and outlet testing commences in late October 2022, followed by commissioning. Commissioning is estimated to take approximately one month to complete, with the clarifier set to be online and operated by Trility, by early December 2022. Module 4 is expected to be online in early 2023.

The new infrastructure will provide the capacity to treat 950L/s of raw water through Module 3 Clarifier and 1100L/s of raw water through Module 4 Clarifier. Townsville’s population is expected to reach 200,000 people in 2022 and with all the positive developments on the horizon, this investment at Douglas Water Treatment Plant will ensure we can continue to meet the demand for clean, healthy drinking water in Townsville as it grows.
