WATER – A total of 44,354,000 gallons of water were treated and delivered, 17,694,000 gallons from Alder Creek treatment plant, 10,940,000 gallons from Brownell Springs and 15,720,000 gallons purchased from City of Portland. Maximum day production was 1.36 MG on July 5th. 1.24 inches of rainfall were recorded at the treatment plant site during the month. The influent header on Filter #3 cracked and was removed for replacement. We had several pump failures at Terra Fern Reservoir during July. Two new pumps have been ordered.
WASTEWATER – A total of 26,950,000 gallons of sewage were treated and pumped to Iseli Nursery for irrigation. Minimum flow was 0.7 MGD on the 3rd. Maximum flow was 1.07 MGD on the 9th. Rainfall was 0.15 inches on the 8th and 0.55 inches on the 9th. A total of 1.22 inches of rainfall were recorded during July. BOD concentration was 13.2 mg/l; BOD loading was 94 lbs; permit allows 10 mg/l and 125 lbs.; SS concentration was 12.9 mg/l; SS loading was 92 lbs.; permit allows 10 mg/l and 125 lbs. Permit limits do not apply when the water is used for irrigation, these figures are shown to demonstrate plant efficiency. 147 metric tons of sludge was procesed and 30 metric tons were hauled and spread on DEQ-approved pasture sites. The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 274 hours with no significant problems. Our contractor completed cleaning and video inspection of all 14,550 lineal feet of the sewer trunk line between University Ave. and the treatment plant during July. The trunk line was in remarkably good condition and no obvious signs of inflow or infiltration were revealed by the inspection. However an unusually large amount of big rocks and debris was found immediately upstream of the treatment plant (see photo).
STREETS & STORM – The street sweeping contractor spent 51 hours sweeping streets and collected more than 15 tons (26 cu. yds.) of debris, covering 165 lane miles.
PARKS, BUILDINGS AND GROUNDS – Parks, Buildings and Grounds staff were kept busy preparing for and cleaning up after the Mountain Festival. We have been able to get a lot of little items taken care of in various parks with our seasonal worker working on Sundays.
