WATER – A total of 38,015,000 gallons of water were treated and delivered during June. 15,270,000 gallons from Alder Creek treatment plant, 7,950,000 gallons from Brownell Springs and 15,035,000 gallons purchased from City of Portland. Peak day production was 1.58 MGD on June 23rd. 6.80 inches of rainfall were recorded at the water treatment plant site during the month. The manufacturers’s field service technician visited the WTP on June 30th to review the existing filters and make recommendations for upgrades.

WASTEWATER – A total of 41,510,000 gallons of sewage were treated and re-used for irrigation. Maximum flow was 2.4 MGD on the 16th (rainfall was 0.35″ on the 15th and 0.51″ on the 16th). Monthly rainfall recorded at the plant was 4.69 inches. 167,180 gallons of sludge were dewatered and landfilled. Effluent BOD loading was 15.1 lbs/day BOD concentration was 2.0 mg/l Effluent TSS loading was 54.29 lbs/day TSS concentration was 7.0 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. These results are well below ‘winter’ permit limits (125 lbs/day and 10 mg/l) and show the effectiveness of the rebuilt effluent filter system. Even with only one filter online we were able to exceed the permit standards despite the unusually wet June we had. The 2.4 MGD peak day referenced above was easily handled by the sole effluent filter in service. A field service engineer from the secondary clarifier manufacturer visited the WWTP on the 30th to review the condition of one of the clarifiers which had been drained for inspection. Murraysmith staff also visited the plant in June to help finalize the recommendations in the pre-design report. A scum pump was replaced the reclaimed water pump that was removed for service on May 12th was returned to service on June 15th. The second RAS pump was installed and placed into service. Both RAS pumps have been replaced with new units. Public Works staff replaced gaskets on air piping with high-temperature gaskets suited for air service.

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.

WATER – A total of 32,84,100 gallons of water were treated and delivered during April. 10,000,000 gallons from Alder Creek treatment plant, 7,936,000 gallons from Brownell Springs and 14,948,100 gallons purchased from City of Portland. Peak day production was 1.2 MGD on April 12th. 3.1 inches of rainfall were recorded at the water treatment plant site during the month.

WASTEWATER – A total of 35,260,000 gallons of sewage were treated and discharged to Tickle Creek. Maximum flow was 2.38 MGD on the 1st (rainfall was 0.31″ on March 31st and 0.26″ on April 1st). Monthly rainfall recorded at the plant was 1,62 inches. 571,670 gallons of sludge were dewatered and stored. Sludge hauling to Wasco County Landfill resumed in April and the sludge accumulated over the winter was removed. Average BOD concentration was 11.8 MG/L (permit allows 10 MG/L) BOD lbs discharged were 69.7 lbs/day (permit allows 125 lbs/day) Average SS concentration was 17.8 MG/L (permit allows 10 MG/L) SS lbs discharged were 106.8 lbs/day (permit allows 125 lbs/day). There were permit violations for weekly and monthly SS and BOD concentration and weekly average ammonia in April. Several pumps at the plant were rebuilt or repaired. The last of five flow meters installed in the collection system was placed into service and regular flow monitoring began.
