At DBCT, we understand water is a precious resource and have taken steps to efficiently use water onsite, as well as protecting water adjacent to the terminal. DBCT set out to achieve a sustainable long-term solution to minimising the potential for wet season impacts on the surrounding Great Barrier Reef World Heritage Area. We recognise it plays an important role in providing a sustainable coastal gateway for the shipping of clean Bowen Basin coals to the rest of the World.

DBCT recently undertook a Water Quality Improvement Project (WQIP) to improve our water management capabilities onsite. You can find out more about it on the WQIP page.

All water onsite is collected and recycled via an extensive water recycling program, with the majority of water onsite being collected rainwater in onsite dams. While DBCT has a water allocation with Sunwater as well as a bore water allocation, these are only accessed when water stocks onsite aren’t enough for operational needs. The total water storage capability onsite is of 2186ML across five dams; the Industrial Dam, Quarry Dam, the new Rail Loop Dam, Rail Receival Dam and Spindler’s Dam.

A flocculant plant is located at the Industrial Dam to help manage water quality and recovery of coal fines from the water.


Flocculant is a chain of environmentally friendly microscopic particles that join together in a polymer chain, which unravels once activated in water. These chains attach themselves to suspended sediment particles to increase the weight and density so they drop out of suspension. With the sediment on the dam floor instead of in suspension, the quality of water discharged, if a release is required, will have a lower suspended particle rate for the receiving environment in the case of an extreme weather event.
