Saltwater and ash are by-products from coal generation and are disposed of at a dry ash repository. EnergyAustralia designed a Leachate Barrier Management System, which involves installing a plastic liner at the base of the dry ash repository, to direct contaminated water to pass through the repository to a series of ponds for treatment and reuse. The Leachate Barrier Management System is an engineered solution that eliminates contamination, ensures regulatory compliance, and provides the business, regulators and the community with confidence that water resources are being protected.
Mount Piper Power Station continues to source water from the Springvale Water Treatment Plant which fulfils about 80% of the plant’s daily water needs, significantly reducing the need to source river water for its operations and, in turn, freshwater consumption.
