UPDATE -August 19, 2025- Citywide fire hydrant flow testing is now complete! Thank you for your patience and cooperation as our team worked to complete this essential maintenance!
The Waupun Utilities' Water Department will begin citywide fire hydrant flow testing on Wednesday, July 16, 2025. This program ensures fire hydrants are fully operational and helps maintain high water quality by removing accumulated sediment. 
Purpose of the Program
The primary purpose of this program is to verify proper operation of the city’s fire hydrants through regular inspections, flow testing, and preventive maintenance.
Secondarily, flushing improves water quality by removing iron and manganese mineral deposits from the water lines. These minerals can cause discoloration, unpleasant taste, and aesthetic issues in drinking water.
