Hydrant Painting, targeting corroded hydrants with paint failure. Hydrant coating assessment will be <br />done during 2023 hydrant servicing and added to the 2024 PW Annual Work Plan within the area <br />indicated on the map below. <br />Hydrant Winterizing <br />x Red Top hydrants (43 hydrants citywide) are hydrants that have a plug at the elbow below <br />grade. The reason for the plug is normally because of a high level of ground water. The result of <br />not checking a plugged hydrant is the possibility of the barrel staying “wet” not draining, then <br />freezing during the winter months. A frozen hydrant barrel can cause damage to the hydrant <br />and cause it to be inoperable for use in the winter months. <br />x Green Top hydrants (40 hydrants citywide) are similar to red top hydrants in the need to check <br />for ground water in the hydrant barrel, but these hydrants are not plugged. The ground water <br />seeps into the barrel and can cause the barrel to freeze during the winter months. PW Staff <br />measures the amount of ground water in the barrel and adds the appropriate amount of a food <br />grade anti-freeze. Like red tops hydrants, if this process isn’t completed annually before the <br />winter months the hydrant barrel could freeze, damaging the hydrant and making it inoperable <br />for use in the winter months.
