Monthly Report – October, 2019 Public Works Department

WATER – A total of 30,797,000 gallons of water were treated and delivered during the October. 9,558,000 gallons from Alder Creek treatment plant, 6,270,000 gallons from Brownell Springs and 14,947,000 gallons purchased from City of Portland. Production at Brownell Springs was still limited to 90 gpm in October and will likely remain at that level until significant rainfall increases streamflow in Cedar Creek. Maximum day production was 1.7 MG on October 22. 5.04 inches of rainfall were recorded at the water treatment plant site during the month.

WASTEWATER – A total of 35,670,000 gallons of sewage were treated and used for irrigation. Maximum flow was 1.73 MGD on the 19th (0.25 inches of rain on 10/18 and 0.86 inches on 10/19). Monthly rainfall recorded at the plant was 6.54 inches. 236,680 gallons of sludge were dewatered and landfilled. Aeration basin 1 and clarifier 2 were cleaned and returned to service. Two reclaimed water pumps were rebuilt. Filter cloth on the effluent filters were replaced with new covers. There were six positive total coliform exceedences (none contained e. coli) during the month. Veolia staff believe this was a result of bacterial regrowth in the effluent pipeline under gravity flow conditions. The Plant Optimization Improvements Project was completed in September.

STREETS – Clackamas County road maintenance staff performed centerline and fog lane striping on City streets. They were unable to complete all streets before the weather turned. The remaining streets will be striped in 2020.
