Street sweepers have the potential to become a key solution for removing stormwater pollutants, but fully unlocking this potential depends on the implementation of comprehensive, standardized testing.
Street sweepers hold substantial potential as a top solution for stormwater pollution control, but realizing this opportunity relies on the implementation of comprehensive, standardized testing. Currently, there is a lack of sufficient data for stormwater professionals, limiting their ability to fully evaluate and utilize the capabilities of modern sweeping technologies.
The advantages of thorough testing are clear. Research has already shown that street sweeping can be up to seven times more cost-efficient than methods like catch basin cleaning in removing pollutants such as nitrogen and phosphorus. Standardized testing would validate these findings, offering concrete evidence that stormwater managers can use to optimize their resource distribution.
Additionally, data-driven insights are essential for obtaining regulatory credits under MS4 permits. If street sweepers can consistently demonstrate effective pollutant removal, regulators will be able to establish more precise and reliable credit systems, encouraging municipalities to invest more in enhanced sweeping programs.
Why should sweeper manufacturers support this initiative? Because standardized testing ensures a fair comparison, allowing superior technologies to stand out. Performance-based regulations, grounded in reliable test results, will foster the use of more advanced equipment. Moreover, it is likely that sweeper routes and their frequency will be expanded.
This creates an opportunity for manufacturers whose sweepers demonstrate exceptional pollutant removal capabilities to gain a competitive edge in the market. Additionally, positive testing outcomes could open the door to funding opportunities, such as those available through the Clean Water State Revolving Fund, as municipalities seek proven solutions for stormwater management.
Disseminating test results through organizations like the National Municipal Stormwater Alliance (NMSA) would be an excellent way to share this vital information within the stormwater community. The NMSA’s “Stormwater Testing and Evaluation for Products and Practices” (STEPP) program could play a key role in establishing standardized testing procedures.
Collaborating with groups like NMSA will drive innovation, raise public awareness, and ultimately position street sweeping as a key component of effective stormwater management.
