WATER – A total of 35,020,000 gallons of water were treated and delivered during March. 12,040,000 gallons from Alder Creek treatment plant, 7,950,000 gallons from Brownell Springs and 15,030,000 gallons purchased from City of Portland. Peak day production was 1.60 MGD on May 27th. 5.37 inches of rainfall were recorded at the water treatment plant site during the month.
WASTEWATER – A total of 40,034,000 gallons of sewage were treated and re-used for irrigation. Maximum flow was 2.15 MGD on the 19th (rainfall was 0.35″ on the 18th and 0.65″ on the 19th). Monthly rainfall recorded at the plant was 5.37 inches. 358,330 gallons of sludge were dewatered and landfilled. Effluent BOD and TSS numbers were not reported since all treated wastewater was re-used for irrigation. A reclaimed water pump failed on May 12th was was sent off for service. A field service team from the effluent filter manufacturer rebuilt effluent filter No. 1 and replaced the filter media with a new product. Effluent TSS levels were below 10 mg/l after the rebuilt filter was placed into operation. The air bladders on the domestic (well) water system and process water system were replaced allowing us to pressurize the systems and more easily determine if there are leaks. Public Works staff installed containment piping to the effluent filter discharge channel and process water discharge line to allow disinfection of one or both process streams.
