Not all carwashes have an integrated water treatment system. In some countries and regions, water and wastewater charges are so low that operators have not yet invested in water treatment.

Reducing fresh water consumption while maintaining consistent high carwash quality is the core sustainability focus in WashTec’s business model. Water treatment systems help to significantly reduce fresh water consumption. Depending on the carwash configuration, the dimensioning of the water treatment system, the selected wash programs, the number of washes and the types of vehicles, significant volumes of fresh water can be saved and process water can be recirculated.
