The Problem
Most pressure washing activities are conducted outside . This often results in the discharge of wastewater to the storm drainage system , unless the equipment operator takes steps to collect and dispose of it legally . Discharge of pressure washing wastewater to the storm drainage system is prohibited because it contains pollutants from the cleaning compounds used and / or from the objects or surfaces being cleaned . Even cleaners labeled “ biodegradable ” and “ non-toxic ” may be harmful to aquatic life , especially after cleaning various surfaces ( e . g . home exteriors , driveways , equipment and more ) that contain oils , greases , chemicals , and other substances .
Any substance , including pressure washing wastewater that enters storm drains flows directly into lakes , rivers , and streams . This water is not treated or cleaned to remove pollutants . Pollutants discharged to the storm drainage system harm fish and wildlife and contaminate recreational sites and drinking water supplies .
Pressure Washing as part of the Solution
Pressure washing is an activity that can help improve the quality of our waters when done properly . By cleaning ( pressure washing ) surfaces ( e . g . equipment , parking lots , sidewalks , buildings , etc .), collecting the wastes ( water and / or debris ), and properly disposing of the wastes , there is less chance of pollutants ending up in our waterways . It is through education , proper collection and disposal that pressure washing can have a positive impact on the environment .
Consider using dry methods for surface pre-cleaning , such as using absorbents on small oil spots and sweeping up trash , debris , or dirt before washing . Remember to pick up pre-cleaning debris as soon as possible and dispose of them properly after use so that they do not enter storm drains .
DISPOSAL REQUIREMENTS AND PROHIBITIONS
Proper disposal of pressure washing wastewater , in compliance with environmental regulations , depends on the nature of the pollutants in it . It is the responsibility of the generator to determine the proper collection and disposal method for wastewater created by pressure washing . To avoid unanticipated costs , delays , and violations , this determination should always be made prior to starting any job . All disposal methods are subject to requirements , restrictions , and prohibitions , as outlined by the City of Arlington .
