2021 Dye Flood Testing
Location: Between East 1st Street and St. Croix Street and between 35th Avenue East and 43rd Avenue East
City workers will be conducting sewer system tests by adding a non-toxic green tracer dye to the stormwater. Dyed water will help identify infiltration and defects with the sewer.
The test will last approximately 2-3 hours in each location.
The green tracer dye poses no threat to human health or the environment. As a result of testing, green water may be seen coming from storm outfalls. All public safety authorities will be notified.
Dye flood testing has been completed on 9/22/2021.
Questions or concerns regarding the dye flood testing should be directed to the City of Superior Environmental Services Division of Public Works at (715) 394-0392 or firstname.lastname@example.org
