WATER – A total of 55,437,000 gallons of water were treated and delivered during the month. 36,079,000 gallons from Alder Creek treatment plant, 4,030,000 gallons from Brownell Springs and 15,328,000 gallons purchased from City of Portland. Production at Brownell Springs was still limited to 90 gpm and will likely remain at that level until Fall rains return. Maximum day production was 2.1 MG on August 14th.  0.94 inches of rainfall were recorded at the water treatment plant site during August. Staff met with Oregon Drinking Water Services in August to iron out the details in the proposed Bi-Lateral Compliance Agreement for cryptosporidium treatment of water purchased from Portland Water Bureau.

WASTEWATER – A total of 20,650,000 gallons of sewage were treated and used for irrigation. Minimum flow was 0.41 MGD on the 31st. Maximum flow was 0.78 MGD on the 18th. No rainfall was recorded at the treatment plant site during the month of August. BOD concentration was 11.0 mg/l; BOD loading was 61 lbs; permit allows 10 mg/l and 125 lbs.; SS concentration was 20.8 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. Work continued on the WW Plant Optimization Improvements. All the air piping was relocated and fitted with new, temperature-resistant gaskets, the flow splitter chamber was poured and several drain and process water lines that had been damaged by the high temperatures were replaced.

STREETS AND STORM – City staff painted crosswalk markings, parking lot stripes and stop bars on City streets in August. Additionally, our striping contractor finished up the remaining centerline and bike lane striping on City streets that they were unable to complete in the Fall of 2017. City crews installed about 100 lineal feet of 18″ storm drain piping in an open storm drain channel south of the the intersection of Tupper Rd. and Dubarko Dr. There were many trees that had sprouted up in this channel over the years sometimes resulting in stormwater overflowing the channel during large storm events. The street sweeping contractor spent about 65 hours sweeping City streets, collecting 34 cu. yds. (26 tons) of debris.

PARKS, BUILDINGS AND GROUNDS – With the warm and dry summer weather the pond that supplies the irrigation system in Sandy Bluff Park was drawn down very low such that the irrigation pump would have been starved for water by the end of the summer. Public Works installed a 1″ water service and meter and connected it to the irrigation piping allowing us to supplement the irrigation system with potable water during dry summers. New engineered wood fiber was installed in the Fantasy Forest, Tupper Park, Bornstedt Park, Salmon Creek Park and Cascadia Village Park playgrounds.

WATER – A total of 55,900,000 gallons of water were treated and delivered during the month. 33,173,000 gallons from Alder Creek treatment plant, 6,450,000 gallons from Brownell Springs and 16,277,000 gallons purchased from City of Portland. Maximum day production was 2.2 MG on July 30th.  0.07 inches of rainfall were recorded at the water treatment plant site during July. The main storage reservoir on Vista Loop Dr. drained in the early morning of July 7th due to a failure in the altitude valve that controls the level. A level sensor also failed so we were getting erroneous data on the reservoir level and as a result the low level alarm that normally would have been tripped did not activate.  Some areas of the City had very low or no water pressure and we were required to issue a boil water advisory. We were able to move water from the Revenue Ave. water reservoir to restore pressure and we were able to find a lab open on the weekend that could analyze the samples we collected. All samples came back negative for coliform contamination and we were able to lift the boil advisory on the 8th. On July 20th the Water Resources Dept. regulated all users on Cedar Creek which requires us to reduce the flow from Brownell Springs to about 90 gallons per minute. We usually get about 250-350 gallons per minute from this source. We have the senior water right in the Cedar Creek basin but it for a very small amount. The Oregon Dept. of Fish and Wildlife has a water right senior to our other rights from Brownell for 25 CFS which is far more than the flow available in Cedar Creek this time of year. One of the booster pumps on the water plant influent line was rebuilt. The other pump will be rebuilt later this summer.

WASTEWATER – A total of 20,950,000 gallons of sewage were treated and used for irrigation. Minimum flow was 0.36 MGD on the 21st. Maximum flow was 0.94 MGD on the 8th. No rainfall was recorded at the treatment plant site during the month of July. BOD concentration was 11.8 mg/l; BOD loading was 66 lbs; permit allows 10 mg/l and 125 lbs.; SS concentration was 46.0 mg/l; SS loading was 147 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 sown to demonstrate treatment efficiency. 22.53 dry tons of sludge were processed in July. Work began on the Plant Optimization Improvements project. The bypass air piping was installed and the contractor began replacing leaking gaskets in the air line.

STREETS & STORM – The street sweeping contractor spent 73 hours sweeping City streets collecting 32 cu. yds. (24 tons) of debris. City crews used 12 tons of asphalt to patch potholes and utility cuts during July. Excess vegetation, weeds and trees were removed from stormwater detention ponds and swales during the month. Since we received no applicants for the seasonal worker position Public Works staff worked on weed cutting and mowing on City streets. This has been a continuing problem, we may have to re-evaluate the pay scale for the Seasonal Worker position for next summer.

PARKS, BUILDINGS AND GROUNDS – In addition to their regular duties Parks staff worked on preparing Meinig Park for the Mountain Festival and restoring the park after the Festival and in preparation for the summer concert and event season. Parks, Buildings and Grounds staff installed a fence in Bornstedt Park to better delineate the leasehold area from the rest of the park.
