Monthly Report-Public Works Department July, 2020

WATER – A total of 47,776,300 gallons of water were treated and delivered during July. 24,506,000 gallons from Alder Creek treatment plant, 7,866,000 gallons from Brownell Springs and 15,404,300 gallons purchased from City of Portland. Peak day production was 1.55 MGD on July 27th. 0.37 inches of rainfall were recorded at the water treatment plant site during the month. The state Drinking Water Services section performed their tri-annual water system survey on June 30th. One of the pumps at Terra Fern reservoir was taken out of service for repairs.


WASTEWATER – A total of 28,050,000 gallons of sewage were treated and re-used for irrigation. Maximum flow was 0.97 MGD on the 1st (rainfall was 0.06″ on the 30th and 0.01″ on the 1st). Monthly rainfall recorded at the plant was 0.3 inches. 330,900 gallons of sludge were dewatered and landfilled. Effluent BOD and TSS loading were both below 10 mg/l. 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 is nearly complete. We complied with our wastewater discharge permit for July. Clarifier #2 was removed form service, cleaned and inspected on July 30th. Veolia and their contractor replaced several components on the sludge belt press which improved performance and production from 50-60 gpm to nearly 100 gpm.

STREETS – City staff started painting parking stalls in City lots and stop bars at arterial and collector street intersections. Clackamas County started centerline, bike lane and fog line striping on City streets in July. Our seasonal worker began work cutting weeds and vegetation in the right-of-way of unimproved streets. 

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.
