Green Bay Water announced the start of its annual water main flushing program on Monday, April 28, 2025, as part of routine maintenance to support safe and reliable drinking water.

According to a press release, Green Bay Water began its scheduled water main flushing program as part of its regular system upkeep. This routine process involves systematically opening fire hydrants to allow water to flow through the system at high speeds, clearing out mineral deposits and sediment that naturally accumulate in the mains over time. The flushing helps maintain water clarity, pressure, and overall system performance, ensuring safe and dependable drinking water for residents. The program covers different neighborhoods on a rotating basis, and water crews post notices and use an online mapping tool to keep the public informed.

During the flushing period, residents in affected areas may temporarily experience low water pressure, cloudiness, or slight discoloration of tap water. Green Bay Water advises customers to run cold water for several minutes if they notice these changes and avoid doing laundry until the water runs clear. The utility recommends checking its website to view the interactive map showing daily flushing zones. While the program may cause brief inconvenience, it is an essential part of maintaining the city’s water infrastructure and ensuring long-term quality and reliability of service.

"The flushing program may cause temporary inconvenience to our customers, but it is necessary to maintain the safety and reliability of our drinking water system," said Green Bay Water General Manager Brian Powell. "We encourage customers to stay informed by checking the GIS map on our website and contacting us if they have any questions or concerns."

The Wisconsin Section of the American Water Works Association (WIAWWA) supports the state’s drinking water community by offering education, information, and networking focused on delivering safe, reliable, and sustainable water. Its members—ranging from utility staff to regulators and students—engage in conferences, workshops, and legislative efforts addressing water-related issues while fostering professional connections statewide and nationally.
