Well 20, Water Reservoir, and Water Tower Back in Service on November 12.
Well #20 Returning to Service
Madison Water Utility is bringing Well #20, its water reservoir, and water tower back into service now that necessary maintenance has been completed. Customers will begin receiving water from this well on November 12, 2026, and may notice a stronger chlorine taste or smell than usual.
Well #20 is in southwest Madison on Prairie Road. The impacted area is mostly south of Raymond Road but could extend further north to the Beltline.
Why might my water taste or smell different?
Well #20 was taken out of service for maintenance. The work included draining and cleaning the water reservoir and applying a new protective coating.
After the work was complete, the reservoir was filled with highly chlorinated water to disinfect the tank. Water Utility staff then spent several days flushing and diluting the water to lower the chlorine level and reduce its taste and smell. Water removed during this process was treated to remove the chlorine before being released. We also took steps to reduce water waste.
Check out the Well 20 Project Webpage to learn more about the project.
Is my water safe to drink?
Yes. Water Utility staff have been carefully monitoring chlorine levels. The chlorine levels in the water are safe, even though you may notice a stronger taste or smell. We expect the taste and smell to return to normal over the next few days.
How can I reduce the chlorine taste or smell?
Some people are more sensitive to chlorine taste and smell than others. If you notice a difference, here are two things you can try:
- Fill a pitcher with water and leave it uncovered in your refrigerator. This allows some of the chlorine to escape.
Use a carbon water filter, which can help reduce chlorine taste and smell.
We apologize for any inconvenience and appreciate your patience as we complete this important project.
