As you read guides about how to maintain your driveway, one of the steps is to pressure wash the surface. You may also be advised to use a degreaser. While this all sounds well and good, the US Environmental Protection Agency (EPA) has another opinion on the matter.

Pressure washing a driveway is not illegal. Under the Federal Clean Water Act of 1972, though, it is illegal to dispose of polluted wastewater into a storm sewer system. This includes storm water drains along city streets. Therefore, pressure washing your driving is not the issue. It’s the runoff water. Take measures to prevent the runoff from leaving your property.

Let’s take a closer look at the Clean Water Act of 1972 and steps to take to legally pressure wash your driveway.

What About Water Usage for Pressure Washing a Driveway?

Water usage laws also need to be considered when you pressure wash your driveway. Most states, counties, and cities have restrictions on how much water a resident can use per month.

How to Pressure Wash Your Driveway Legally

Make pressure washing your driveway a two-person job. Have someone follow closely as you use the pressure washer. Clean up all the runoff as you slowly work along your driveway.

Berming

Berming is another technique that helps to keep polluted runoff on your property. The idea is to use materials that stop the runoff before it reaches the street.

Just make sure that the runoff stays completely on your property.
