Water Leak Adjustment

Have you noticed that your water bill has suddenly doubled in size? You may have a leak.

The City offers a one-time leak adjustment to your bill if you qualify. Qualification criteria and instructions on how to apply for the leak adjustment is detailed below.

Criteria for One-Time Leak Adjustment

Water service leak repair responsibility is defined by the service line. City responsibility ends where private service line begins.
