Street sweepers are essential in reducing pollution run-off from streets. They fall under Pollution Prevention and good housekeeping practices in the MS4 Permit. The street sweeping crew operates street sweepers to remove trash and debris from City streets. Streets with Curb and Gutter are swept at least every two weeks. Removing this debris enhances the appearance of our City and is a cost-effective technique to maintain our stormwater network by removing debris and pollutants before it reaches the stormwater system.
