New street sweeper – first in the fleet

The City of Sammamish added a high-efficiency regenerative air street sweeper to the fleet. This new equipment will help the City keep streets cleaner, reduce pollutants entering local streams and lakes, and improve overall stormwater quality.

The purchase was made possible with support from the Washington State Department of Ecology through the Stormwater Financial Assistance Program, which covers approximately 75% of eligible costs. The City will provide the remaining 25% match and cover the balance of the sweeper’s cost.

Street sweeping plays an important role in protecting water quality and preventing flooding by removing debris, leaves, and other pollutants before they reach storm drains and waterways. This is especially important for protecting salmon against emerging contaminants like 6PPD-Q that are deadly to salmon.

Street sweeping can remove these harmful by-products before they reach our streams and lakes and harm salmon. Adding this sweeper to the fleet will also allow the City to increase the frequency of sweeping, respond more quickly to storm events, and provide a higher level of service for the community.

This investment reflects Sammamish’s ongoing commitment to environmental protection and responsible infrastructure management because runs on alternative diesel, which has less GHG emissions.. The new sweeper is expected to arrive in the fall, marking an important milestone in the City’s efforts to improve stormwater management.
