Depending on the power-washing chemicals used and the contaminants removed from the concrete, water runoff may be prohibited from entering storm sewers.
Municipal codes vary greatly depending on the location.
Some regulations, for example, require all discharge to be hauled to a waste-disposal site. Check with the local Environmental Protection Agency office for information on disposal requirements.
