Car washing generates wastewater containing dirt, road dust, mud, detergents, oils, grease, and suspended particles. Without appropriate treatment, this wastewater can create disposal challenges and increase freshwater consumption. Varuna designs car wash ETP solutions according to wastewater characteristics, daily washing volume, site conditions, and the intended use of treated water. Depending on the project requirements, the treatment system may incorporate screening, grit and oil separation, settling, filtration, and additional treatment stages. For facilities seeking water conservation, suitable treatment and recycling configurations can help recover water for compatible non-potable applications, subject to treated-water quality and applicable requirements.


Every car wash facility has different water consumption and wastewater generation patterns. Varuna offers application-specific solutions starting from 1 KLD and above. The appropriate capacity and treatment process are determined by daily wastewater generation, peak flow, contaminant levels, available space, and intended water reuse.
For independent car washing and vehicle cleaning businesses.
For vehicle washing areas associated with showrooms and dealerships.
For wastewater generated during vehicle washing and cleaning activities.
For facilities providing exterior cleaning, polishing, and detailing services.
For commercial vehicle fleets, transport operators, and logistics facilities.
For bus depots and other facilities with suitable vehicle washing requirements.
Varuna provides customized ETP solutions designed around the water usage, wastewater characteristics, and operating conditions of each car wash facility.
