Water management is a material issue for WesCEF, and senior management is responsible for assessing and managing water-related risks and opportunities. The WesCEF divisional board has oversight of these strategic risks and opportunities. We recognise that there are water-related challenges in many parts of Australia and our focus is on using water more efficiently, reducing our water use intensity and replacing scheme water with reclaimed or recycled water where possible.
This year, the Group recorded water use of approximately 6,000 megalitres which is almost 12 per cent higher than last year. This increase in water use was primarily related to increases in year-on-year production volumes at WesCEF’s chemicals businesses.
WesCEF sees water security as a business-critical risk at its CSBP Kwinana site with current and future threats to availability, reliability and cost of traditional water supply options key considerations for its management team. During the year, WesCEF completed developing a long-term water sustainability strategy for its CSBP Kwinana site. This will ensure the site’s long-term water supply, plant reliability and effluent discharge security, and allow CSBP the opportunity to use climate-independent water sources.
This involved assessing available water sources and options to improve wastewater treatment, including the revitalisation of the site’s three hectares of purpose-built wetlands. The wetlands are an important part of CSBP’s wastewater management, naturally treating approximately 2.5 million litres of nutrient-rich wastewater each day.
A focus area for next financial year is the potential construction of a wastewater recycling plant. The plant will remove metals from the wastewater before directing clean water back to CSBP’s processing plants.
