"Dry Methods for Cleaning"
Washing paved areas can cause debris, vehicle fluids, and other pollutants to be carried into drainage systems with wash water. Sweep and use other dry methods to clean pavement instead of hosing it down. Be sure to pick up and dispose of the accumulated materials properly. Mechanized street sweepers are effective at removing sediment and debris from roads and other paved areas.
If you must wash a paved area, remove as much residue and debris as possible before applying water. Screen storm drain inlets with filter fabric to catch soil and other particles.
It is illegal to dump unused products onto the pavement or down a storm drain!
