WATER – A total of 40,544,000 gallons of water were treated and delivered during the month. 22,151,000 gallons from Alder Creek treatment plant, 4,010,000 gallons from Brownell Springs and 14,383,000 gallons purchased from City of Portland. Production at Brownell Springs was still limited to 90 gpm in September and will likely remain at that level until Fall rains return. Maximum day production was 2.12 MG on September 3rd.  1.59 inches of rainfall were recorded at the water treatment plant site during the month.

WASTEWATER – A total of 20,210,000 gallons of sewage were treated and used for irrigation. Minimum flow was 0.42 MGD on the 27th. Maximum flow was 0.81 MGD on the 12th. No rainfall was recorded at the treatment plant site during the month of September. BOD concentration was 13.0 mg/l; BOD loading was 61 lbs; permit allows 10 mg/l and 125 lbs.; SS concentration was 36.2 mg/l; SS loading was 115 lbs.; permit allows 10 mg/l and 125 lbs. Monthly permits limits for BOD and TSS do not apply when the effluent is used for irrigation. These numbers are shown to demonstrate treatment efficiency.
