November 12-December 31, 2019 Operations Report
/Kevin Southworth, Operations Manager
During this period:
Swim lake spillway project has been designed and we are coordinating with RAM Construction to begin installation of a new water level control structure to replace the wooden stop log setup. Project may start in January contingent on weather and lake level.
Turbidity issues:
December turbidity levels remained below 0.3 NTU, meaning we will not receive a violation for that month. However, we will receive a violation for November that will require another public notice.
We visited an East Sound water treatment plant on Orcas Island on November 15 as part of our DOH plan to control turbidity. Based on this visit and subsequent jar testing we decided to test ferric chloride as our primary coagulant instead of alum.
We calibrated our SCADA system and set alarm points that will alert operators if turbidity reaches certain levels.
Coffman Engineering has completed a report “Water System Treatment, Pumphouse, and Discharge Improvements”.
Settling Pond Permit: Coffman Engineering is also assisting us with our Dept. of Ecology permit for our settling pond. Bids are out to conduct a survey of the water treatment facilities area to use as a site plan as required by the permit.
Fixed leak near meter at 70027 on December 9.
Replaced 30 meter registers for battery failure.
