We understand the important role of water in our local environment and how we can use this resource sustainably
Port Waratah uses water for operational purposes, such as dust suppression, wash downs, firefighting systems and irrigation. Water management remains one of the key environmental concerns for our local community and we must comply with all water-related conditions specified in our Environment Protection Licences (EPLs), consents and other regulatory licences, while using water sustainably. Unfortunately, our performance was below our target, experiencing six water related incidents at our Kooragang Terminal in 2020. The incidents were largely caused by limitations of controls or infrastructure, which has led to extensive investigations and works to improve controls. In 2020, 16 capital projects were implemented and more than $4.3 million invested to improve water management systems at both terminals.
Kooragang Water Management System Automated
The water management systems at Port Waratah comprise substantial infrastructure of storages and connecting pipework, drains and pumping systems. The control of water onsite uses Programmable Logic Control systems that utilise field sensors and transmitters to monitor and control the storage and transfer of water.
During 2020, the last major storage at the Kooragang Terminal was integrated with the automated water management system, removing the need for personnel to manually operate transfer pumps, which often took place during the night and/or rain. The project involved a $2.5 million investment to install new pumps, pipework and level telemetry that now automates the transfer of water to and from the storage. This major improvement to the water infrastructure enables the refinement of efficient system operation and maximises available storage.
