WATER – A total of 26,706,570 gallons of water were treated and delivered during the month. 11,500,000 gallons from Alder Creek treatment plant, 9,435,000 gallons from Brownell Springs and 5,771,570 gallons purchased from City of Portland. The Portland Water Bureau shut off the Bull Run supply on February 13th due to the presence of Cryptosporidium oocysts in several samples from Bull Run. We were able to keep up with demand using our Alder Creek and Brownell Springs sources. Maximum day production was 1.12 MG on February 15th. 12.87 inches of rainfall were recorded at the treatment plant site during the month. CH2M inspected the filter media in the large filter unit at the treatment plant and removed some clogged media from the unit. Replacement media will be placed in March.
WASTEWATER – A total of 85,270,000 gallons of sewage were treated and discharged to Tickle Creek. This is the highest monthly flow total recorded at the plant, an average of over 3,000,000 gallons per day. Minimum flow was 1.23 MGD on the 2nd. Maximum flow was 6.85 MGD on the 5th. Rainfall was 1.85 inches on the 4th and 1.90 inches on the 5th. A total of 13.62 inches of rainfall were recorded at the treatment plant site during February. This month was unusual in that rainfall totals at the water treatment plant have always been higher than at the wastewater plant. BOD concentration was 7 mg/l; BOD loading was 186 lbs; permit allows 10 mg/l and 125 lbs.; SS concentration was 10 mg/l; SS loading was 246 lbs.; permit allows 10 mg/l and 125 lbs. We exceeded the monthly average for lbs of BOD and suspended solids but the mas load limits are suspended when the daily flow exceeds 2.5 MGD. All samples were taken on days when flow exceeded 2.5 MGD so we do not believe violations will result from these exceedences. No sludge was processed, hauled or spread during the month. The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 915 hours with no significant problems.
STREETS & STORM – The street sweeping contractor spent 74 hours sweeping streets and collected more than 34 tons (41 cu. yds.) of debris, covering 239 lane miles. During the few dry days we had in February we were able to get out and perform temporary repairs on several potholes. There are some areas that will require complete excavation and replacement that will have to wait for dry weather. Fortunately most of our streets held up very well (compared to nearby County roads and ODOT highways) after the freezing and unusually wet weather.
PARKS, BUILDINGS AND GROUNDS – PB&G staff repainted the lunch/break room in City Hall to make it match the rest of the building and started to prep for spring mowing. New engineered wood fiber was placed in the playgrounds at Meinig Park and Tupper Park.
