Monthly Report – August, 2020 Public Works Department

WATER – A total of 52,084,929 gallons of water were treated and delivered during August. 28,930,000 gallons from Alder Creek treatment plant, 7,780,000 gallons from Brownell Springs and 15,374,929 gallons purchased from City of Portland. Peak day production was 2.22 MGD on August 14th. 0.63 inches of rainfall were recorded at the water treatment plant site during the month. One of the raw water booster pumps was removed for repairs.

WASTEWATER – A total of 27,150,000 gallons of sewage were treated and re-used for irrigation. Maximum flow was 0.96 MGD on the 26th. Monthly rainfall recorded at the plant was 0.42 inches with a peak of .25 inches on the 17th. 695,060 gallons of sludge were dewatered and landfilled. Effluent BOD and TSS loading were both 8 mg/l. Effluent pounds BOD and TSS discharged was 45 lbs. Permit allows 10 mg/l and 125 lbs.
We complied with our wastewater discharge permit for August. Even though effluent BOD and TSS limits do not apply when treated wastewater is reused for irrigation these results are shown to demonstrate the effectiveness of treatment. Theses results are below the ‘winter’ permit limits (10 mg/l) and show the effectiveness of the rebuilt effluent filter system. The work on the remaining filter was delayed by the outdoor air quality issues. Clarifier #2 was returned to service and Clarifier #1 was cleaned and inspected. Veolia staff repaired several pumps at the plant site and sent one pump off for repairs.

STREETS – City staff continued painting parking stalls in City lots and stop bars at arterial and collector street intersections. Clackamas County finished centerline, bike lane and fog line striping on City streets in August.

PARKS, BUILDINGS AND GROUNDS – The tenant moved out of the rental house at Bornstedt Park in July. While the house was between tenants there was a leak in the plumbing that damaged some drywall. We turned in the claim to our insurance carrier and are waiting for the claim to be resolved to get the repairs made. In the meantime P, B&G staff cleaned up the grounds around the house and removed some overgrown vegetation. We re-opened the restrooms in Meinig Park and at the Transit Center on weekdays in July. We were unable to fill the Parks Seasonal Worker position so we do not have weekend coverage that would allow us to keep restrooms open on weekends. We do have portable toilets in Meinig and other parks that are cleaned daily by the servicing company to accommodate park users.
