WATER – A total of 28,147,000 gallons of water were delivered, 4,571,000 gallons at Alder Creek treatment plant, 10,320,000 gallons at Brownell Springs and 13,256,000 gallons purchased from City of Portland. 9.05 inches of rainfall were recorded at the treatment plant site during November. The state Drinking Water Program performed its triennial inspection of the treatment and distribution systems on the 5th. No significant items were noted, we should receive the written report after the first of the year. A critical component in the Supervisory Control and Data Acquisition System (SCADA) at the water plant failed and was replaced. It took a couple of days to get everything back to normal at all sites. Problems with pump control valves at the Hudson Rd. booster pump station just before Thanksgiving forced us to shut down the PWB source for about a week. The valves were still under warranty and the contractor was able to get them properly adjusted within about a week.

WASTEWATER – A total of 50,460,000 gallons of sewage were treated and discharged to Tickle Creek. Minimum flow was 1.09 MGD on the 20th. Maximum flow was 2.8 MGD on the 23rd. (rainfall was 0.40 inches on the 22nd and 0.65 inches on the 23rd). A total of 6.96 inches of rainfall was recorded during November.  BOD concentration was 11.9 mg/l; BOD loading was 342 lbs.; permit allows 10 mg/l and 125 lbs.; SS concentration was 12.8 mg/l; SS loading was 158 lbs.; permit allows 10 mg/l and 125 lbs.  Effluent BOD and SS permit limits do not apply when the treated wastewater is used for irrigation – these figures are shown to demonstrate treatment efficiency. 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 532 hours with no significant problems.

PW staff also repaired several sewer laterals both in the right-of-way and on private property damaged by the FTTH contractor.

STREETS – The street sweeping contractor spent 94 hours sweeping streets and collected more than 90 tons (136 cu. yds.) of debris, covering 399 lane miles.

PARKS / OTHER –  The top (about 30 feet) of a cedar tree adjacent to Knollwood Park broke off during the windstorm on the 14th. Fortunately, it landed upright, leaning on another tree and did not cause any damage to the park. Our arborist took it down on the 18th – we are keeping the largest part of the tree at the park where it could be used as large woody debris in the stream channel. Parks staff took advantage of breaks in the weather to install Christmas lighting on City buildings and at Civic Plaza.

PW staff resumed cleaning catch basins and removing filters from catch basins in new developments where home construction is nearly completed.
