Ensure your unroofed wash bays are compliant
Unroofed wash bays, particularly those over 20 square metres, require specialised water management to remain compliant with strict local authority and environmental standards.
GPS Environmental provides first flush diversion systems designed to automatically capture the initial, contaminated rainwater runoff from your wash pad.
Because this “first flush” picks up residual oils, grease, and suspended solids from the concrete surface, it must be diverted to an approved pre-treatment device—such as an oil water separator—rather than draining directly into the environment.
This automated diversion ensures that untreated wash water is never discharged directly into drains, a practice that is strictly prohibited by environmental regulations.
