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.

November 16-December 6, 2021 Operations Report

Kevin Southworth, Operations Manager

During this period:

• Water treatment was offline from November 16-20 while stormwater runoff conditions created high turbidity in the reservoir. Treatment resumed on November 21 after confirming the treatment plant could produce clean and healthy water. Since November 21 treated water has been well within turbidity standards and no boil water advisory was needed. There was a brief turbidity spike on November 15 which will result in a turbidity violation notice for November.

• Removed kayaks and skiff from the Clubhouse beach area, moved to the boat trailer parking area.

• Coordinated with Public Works with a plan to stop flow of Aiston Creek at Holiday Lake Dam. This was to enable the road crew to clear the culvert at Beach Ave and Aiston Creek Dr. The road crew was able to clear the culvert on December 6 without stopping the creek.

October 24-November 15, 2021 Operations Report

Kevin Southworth, Operations Manager

During this period:

• Water use status returned to “Normal” October 31 as reservoir levels increased to historical levels.

• Replacement blowoff valve at the Holiday Lake dam spillway on November 11.

• Keith Doran, Arborist removed three trees, including a large tree growing in the Holiday Lake Dam as required by DOE Dam Safety, and also chipped piles from fallen trees at various locations on November 11.

• November 15 presented multiple emergencies due to heavy rains:

  • The Dickenson Lake reservoir level increased 3 feet in 24 hours, and the Holiday Lake Dam reached maximum overflow. .

  • The storm runoff into the lakes resulted in very turbid water. The treatment plant was not able to reduce turbidity to drinking water standards. Until the lakes settle out, no water treatment will happen. There is enough storage of water in the tanks to supply the system for days. We have asked all water users to conserve until we can treat water again.

  • At Beach Ave between Aiston Creek Drive and Cedar Ave the road washed out, exposing and breaking a water main. This caused an estimated 80 gallon per minute leak until that section of the main was valved off. Three residential connections are without water service until we can safely access and repair the broken main.

  • A power outage and related road closure on Seacrest mid-morning cut off all vehicle access to the north end of the island.

• The water treatment main pump relay was replaced on October 15 by PMG Controls.

August 9-September 5, 2021 Operations Report

Kevin Southworth, Operations Manager

During this period:

• New finished water turbidimeter has been tested and is operational.

• Vertical profiling and water samples with a WWU student began August 17, continuing twice per month into autumn. Analysis of organics in the water will be performed at the WWU lab.

• Changed depth of reservoir pump for optimum source water conditions.

• New signage at the lake area and marina was installed.

• Water usage loss is much lower than during the main break ending in July. The unaccounted for water (loss) for August indicates cumulative leaks at valves in the distribution system that need to be replaced.

Coming up:

• Marina docks to be completely removed by October 11, weather permitting. Small docks may be removed after the end of September if equipment is available on the island during dry dock..
