December 7, 2021-January 24, 2022 Operations Report

Kevin Southworth, Operations Manager

During this period:

• The water main break near 1136 Beach Ave (road washout) was temporarily repaired/stabilized on December 23.

• On December 23 a new water loss of about 7-10 gallons per minute (gpm) registered on our charts. This happened right before the snow and extended freeze. This main break was finally isolated to the area of 1237 Beach Ave and repaired on January 21. The cause of this leak was due to tree roots growing around the main. Currently there is an additional 6-7 gpm loss, leak detection and isolation is in process.

• Approximately 14 residences experienced burst pipes during and after the freeze, beginning on December 29, and we continue to hear about newly discovered damage as owners return to their homes. Major water loss and depletion of our water storage tanks was averted by monitoring new meter usage constantly. This saved our water storage and minimized water damage to property.

• The Clubhouse also had a burst pipe and is pending repair. As such the Clubhouse is closed (normal for the off-season) until water service can be restored.

• The Operations Shop door was replaced by a metal frame/door by Nick Kluge on January 22. This is to increase security after the previous wooden door/frame was pried open by a burglar on March 3, 2021.
