Many communities in the Bay watershed have street sweeping programs, though most are not designed specifically for nutrient and sediment removal. The sweepers may reduce trash or toxic contaminants, which are abundant in urban street solids, but older technologies, like mechanical broom sweepers do little to reduce nutrients and sediment. Upgrading to more effective technologies like Regenerative Air Sweepers and Vacuum Assisted Sweepers can help earn a modest nutrient and sediment reduction toward meeting TMDL goals.
Below are several resources including the Expert Panel report on the nutrient and sediment reductions that can be earned by upgrading your sweeper fleet, and CSN’s fact sheet to help you get started!
