Treatment Processes
Vehicle Wash Water
Contamination of surface waters arises when wash water is illegally discharged to storm drains, which in turn most commonly drain to rivers and lakes. Main pollutants in wash water include phosphates; oil and grease; and lead.
As a minimum requirement, vehicle washing facilities should capture contaminants from wash water before being released into sewer systems. However, as vehicle washing also uses significant quantities of water, it is more desirable to utilise a water reclamation system to reduce water usage and thus the environmental footprint of the washing process.
