Washbay specialists completed a full upgrade of the wheel wash system at Wang Ash Dam in Wallerawang, NSW, for Generator Property Management. The outdated system was removed and replaced with a custom-built, in-ground wheel and underbody wash designed to handle heavy-duty vehicle traffic and meet strict environmental compliance standards. The project included demolition of the existing infrastructure, site remediation using selective road base and reseeding, and construction of a reinforced concrete pit to house the new high-pressure system. The installation featured automated controls and wide-angle spray nozzles for efficient sediment removal and vehicle cleaning. Solve Civil also provided system commissioning, staff training, and detailed maintenance documentation to ensure smooth operation. The result is a durable, low-maintenance solution that improves site efficiency, reduces environmental impact, and ensures vehicles leave the site clean and compliant.
