Mobile Vehicle Washers

Mobile Vehicle Washing Program

The City requires mobile washing businesses to collect and discharge washwater into the sanitary sewer system. Washwater is prohibited from entering the City's stormwater system. Pollutants of concern are pH and oil and grease. The mobile vehicle washing ADCM requires BMPs to ensure that all washwater is collected, the washwater meets City discharge limits, and sanitary sewer overflows are prevented. Other requirements may include specific volume and rate of discharge limits and a "dry weather only" provision.
