• One elevated storage tank. <br />o Recently rehabbed in 2014. <br />• One booster station <br />o Currently undergoing major upgrades and will have additional upgrades in the next <br />three to five years. <br />• 162.6 miles of watermain <br />o Average age 45.4 years old <br />o Approximately 72% of the water distribution system was installed between 1959 and <br />1967. <br />o Average watermain rating of 3.1 (1-5 with 5 being best) <br />0 10 -year average of watermain breaks is 33 per year. Trend is flat. <br />• 1608 valves <br />• 1743 hydrants <br />• 10,400 water meters <br />o Most have been replaced in the last 5 years. <br />Current Capital Improvement Plan investments of $500,000 annually for watermain replacement <br />for the next 4 years increasing to $1,000,000 in 2023.
