Monthly Report July, 2014 – Public Works Department

WATER – A total of 49,236,000 gallons of water were delivered, 18,323,000 at Alder Creek Treatment Plant, 15,713,000 at Brownell Springs and 15,190,000 purchased from City of Portland. Peak day water delivery was 2.211 MG on the 30th. A total of 1.38 inches of rainfall were recorded at the treatment plant site during July.  The contractor completed most of the punchlist items for the Intertie Project . There are still some issues with the landscaping at both sites. The landscape subcontractor will be back in the Fall to replace dead plants and perform maintenance and weeding. We are holding back some retainage until this work is completed. The contract should be finalized in October or November.

SEWER – A total of 29,550,000 gallons of wastewater were treated and pumped to Iseli Nursery and used for irrigation. Minimum flow was 0.86 MGD on the 28th. Maximum day flow was 1.2 MGD on the 23rd. Rainfall was .20″ on July 22nd and .60″ on the 23rd.  1.30 inches of rainfall were recorded at the treatment plant site during July.  BOD concentration was 15.7 mg/l; BOD loading was 132 lbs.; permit allows 10 mg/l and 125 lbs.; SS concentration was 7.2  mg/l; SS loading was 60.0 lbs.; permit allows 10 mg/l and 125 lbs. We were in compliance with our discharge permit for the month of July. Effluent BOD and SS permit limits do not apply when the treated wastewater is used for land application – these figures are shown to demonstrate treatment efficiency.   No sludge was processed during the month.  The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 670 hours with no significant problems.

STREETS – The street sweeping contractor spent 50 hours sweeping streets and collected more than 17 tons (25 cu. yds.) of debris, covering 154 lane miles. City crews replaced several water services under Dubarko Rd. prior to the paving project.

PARKS / OTHER –  The splash pad at Bornstedt Park continues to be very popular – over 600,000 gallons of water were used for turf irrigation and the splash pad.  Meinig Park fared well through the Mountain Festival and the new lighting has resisted vandalism so far.

The FTTH project has consumed more staff time than anticipated. The volume of utility locate requests has required at least one and sometimes two PW staff members to keep up with the requests.
