The City of Dubuque has launched a proactive water leak detection survey, with crews inspecting fire hydrants in the northeast part of the city using specialized acoustic equipment to identify any underground leaks in the water system. The survey is expected to continue through the middle of next week and will take place during the day, evening, and weekend to minimize disruptions.

Why it matters

Even small underground leaks can waste significant amounts of treated drinking water and may eventually cause infrastructure damage or service disruptions. By identifying potential leaks early, Dubuque can prioritize preventative maintenance, reduce water loss, and maintain reliable service for residents.

The details

Crews from the contracted company Westrum Leak Detection, Inc. will focus exclusively on Pressure Zone 2, which serves the northeastern portion of Dubuque. They will use specialized acoustic listening equipment to detect the sound of water moving beneath the surface at public fire hydrants. If unusual water noise is detected, a follow-up visit will be scheduled during evening hours when overall water usage is lower to more accurately pinpoint potential leaks in water mains or private service lines.

  • The survey began on Friday, February 27, 2026.
  • The survey is expected to continue through the middle of next week.
