Changes to the volume of water entering the system through different turnouts and wells can cause pressure variations within the water system. The City actively monitors the system to ensure that water pressures meet American Water Works Association standards. To ensure balanced water system pressures and improve the reliability of Turnout No. 1, a project was initiated to upgrade the existing 12-inch water main to an 18-inch water main and replace the piping and specialty equipment inside Turnout No. 1.
