WATER – A total of 33,128,000 gallons of water were treated and delivered during the month. 11,848,000 gallons from Alder Creek treatment plant, 7,180,000 gallons from Brownell Springs and 11,100,100 gallons purchased from City of Portland. Maximum day production was 1.23 MG on December 11th. 7.0 inches of rainfall were recorded at the water treatment plant site during the month. Due to a communications failure in the SCADA system we did not take any water from the PWB source between December 9th and December 14th. Public Works had a water leak repair callout on Christmas Day.

WASTEWATER – A total of 41,970,000 gallons of sewage were treated and discharged to Tickle Creek. Minimum flow was 0.7 MGD on the 15th. Maximum flow was 2.9 MGD on the 29th. Rainfall was 0.8 inches on the 28th and 0.6 inches on the 29th. A total of 4.55 inches of rainfall were recorded at the treatment plant site during December.

There were three weekly ammonia permit violations and one monthly average permit violation.
