WATER – A total of 20,253,584 gallons of water were produced, 2,078,000 gallons from Alder Creek treatment plant, 9,979,000 gallons from Brownell Springs and 8,195,584 gallons purchased from City of Portland. 3.52 inches of rainfall were recorded at the treatment plant site during May. The Revenue Ave. reservoir was drained as part of the 1-year warranty inspection for the PWB Intertie project. The warranty inspection revealed a few issues, mostly related to painting and landscaping at the pump stations. There were also some minor cosmetic concrete repairs required on the interior of the reservoir and as a result we had to keep it drained for about two weeks. A lighting strike on the 19th affected several items at the treatment plant and Springs but they were repaired or replaced quickly.

WASTEWATER – A total of 35,860,000 gallons of sewage were treated and used for irrigation. Minimum flow was 0.9 MGD on the 22nd . Maximum flow was 1.45 MGD on the 1st. (rainfall was 0.0 inches on April 30th and 0.2 inches on May 1st). A total of 1.37 inches of rainfall was recorded during May.  BOD concentration was 6.1 mg/l; BOD loading was 60 lbs; permit allows 10 mg/l and 125 lbs.; SS concentration was 10.2 mg/l; SS loading was 101 lbs.; permit allows 10 mg/l and 125 lbs.   No sludge was processed, hauled or spread during the month. Repairs to Clarifier No. 2 were completed. The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 308 hours with no significant problems.  

STREETS – The street sweeping contractor spent 58 hours sweeping streets and collected more than 12 tons (17 cu. yds.) of debris, covering 154 lane miles. Approximately 26,000 lineal feet of cracks were sealed on various City streets. PW staff finished installing the wayfinding signs in May.

PARKS / OTHER – The drier weather in May allowed Parks staff to keep up with the mowing however the warmer weather made the grass grow that much faster. PW staff installed water meters on the splash pad, irrigation service and rental house at Bornstedt Park. This will allow us to keep track of water usage for each feature and reduce monthly sewer bills which had been based on a single meter. The one year warranty inspection for Bornstedt Park was performed. The contractor connected the irrigation for the community garden to the on-site well which will further reduce utility bills. It was supposed to have been done as part of the project but was not discovered until the garden was prepared. The contractor will replace several trees and shrubs that are not thriving later in the Fall. PW staff installed a new water service and standpipe in the dog park during May.
