Project Overview

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.

Timeline 

Dye flood testing has been completed on 9/22/2021.
