The trunk line was in remarkably good condition and no obvious signs of inflow or infiltration were revealed by the inspection. However an unusually large amount of big rocks and debris was found immediately upstream of the treatment plant (see photo).

STREETS & STORM – The street sweeping contractor spent 48 hours sweeping streets and collected more than 10 tons (18 cu. yds.) of debris, covering 152 lane miles. We were able to take advantage of the dry weather and get a contractor in to replace damaged sidewalk panels at City parks and associated with water or sewer repair projects. During the same stretch of dry weather PW staff installed about 250 feet of 12″ storm drain pipe and a catch basin in Tupper Rd., eliminating a roadside ditch that was difficult and expensive to maintain.

WATER – A total of 30,279,000 gallons of water were treated and delivered, 8,577,000 gallons from Alder Creek treatment plant, 10,940,000 gallons from Brownell Springs and 10,762,000 gallons purchased from City of Portland. Maximum day production was 1.12 MG on December 14th. 19.85 inches of rainfall were recorded at the treatment plant site during the month. We took no water from the Portland Water Bureau source for about 10 days in December due to elevated turbidity in the Bull Run system as a result of the heavy rains we had during the month. While these elevated turbidity levels still comply with the regulations for an unfiltered source like Portland’s it does require extra sampling and monitoring on our part. It is easier to turn off the PWB source and draw more water from Alder Creek and Brownell Springs during these events. Even though we can treat the water from Alder Creek its water quality was equally affected by the heavy rain. CH2M staff worked diligently to meet standards during these high rainfall and streamflow events.

STREETS & STORM – The street sweeping contractor spent 73 hours sweeping streets and collected more than 40 tons (70 cu. yds.) of debris, covering 241 lane miles. The stormwater system responded well during the heavy rain events; we had crews out checking trouble spots during the heaviest rains and most of the problems were caused by storm drains blocked by leaves and debris from the wind storms.

PARKS, BUILDINGS AND GROUNDS –  More trees blew down at the east end of the Tickle Creek Trail with each storm event, however few of them fell on the trail itself.

Maximum day production was 1.62 MG on October 15th. 5.84 inches of rainfall were recorded at the treatment plant site during the month the vast majority of which fell on October 31st. The roof at the treatment plant was replaced in October. The original tile roof was in relatively good condition but there were about 30 broken tiles which led to several leaks. These tiles are no longer manufactured so the only alternative was to replace the roof. City staff replaced a valve and drained the 2.0 MG concrete reservoir on Vista Loop for inspection and cleaning. It will be returned to service in November.

WASTEWATER – A total of 39,170,000 gallons of sewage were treated and re-used for irrigation. Minimum flow was 0.93 MGD on the 6th. Maximum flow was 3.3 MGD on the 31st.

These figures are shown to demonstrate treatment efficiency.13.67 metric tons of sludge were processed in October and 17.86 metric tons were hauled and spread on local pasture land. The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 344 hours. A pump at the Southwest pump station was sent in for repairs.

These figures are shown to demonstrate treatment efficiency.Twenty-seven metric tons of sludge were processed in September and 16.2 metric tons were hauled and spread on local pasture land. The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 253 hours with no significant problems.

These figures are shown to demonstrate treatment efficiency. Forty-four dry tons of sludge were processed in August and 41 dry tons were hauled and spread on local pasture land. We had a significant failure on the standby generator at the the plant, costing over $42,000 to repair. The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 238 hours with no significant problems.

PARKS / OTHER – The existing irrigation pump at Sandy Bluff park was repaired and returned to service in August. Resuming Irrigation and the rain we had in August allowed the grass in the park to start greening up again.

WATER – A total of 58,678,100 gallons of water were delivered, 37,767,000 gallons from Alder Creek treatment plant, 5,270,400 gallons from Brownell Springs and 15,640,700 gallons purchased from City of Portland. This is a new monthly record for water production. On July 6th,  the Oregon Water Resources Department required us to reduce the amount of water we take from Brownell Springs to about 90 gallons per minute due to low flow in Cedar Creek. Cedar Creek also supplies the Sandy Fish Hatchery. This has happened in the past, typically in September or October. However this is the earliest we have ever had to reduce withdrawal from the Springs. On the 30th treatment plant staff placed plastic sheeting on the upstream face of the wing dam to provide more water to the Alder Creek intake. 0.41 inches of rainfall were recorded at the treatment plant site during July.

These figures are shown to demonstrate treatment efficiency. Sludge processing began in June and sludge hauling started on July 7th. Twenty-one dry tons of sludge were processed in July and 41 dry tons were hauled and spread on local pasture land.  Clarifier No. 2 was drained for inspection and cleaning. The pumps at Marcy St.; Northside, Southside, Southeast, Southwest and Meinig Ave. lift stations ran a total of 203 hours with no significant problems. City crews doing routine sewer line cleaning discovered a FTTH conduit bored directly through an 8″ sewer main on Loundree Drive.  Fortunately, we discovered it before it could cause a backup and it was repaired on the 22nd.

STREETS – The street sweeping contractor spent 61 hours sweeping streets and collected more than 16 tons (22 cu. yds.) of debris, covering 212 lane miles. These totals include sweeping after the Mountain Festival parade.  A total of 9 tons of asphalt were used patching potholes and making street repairs in July. Considerable time was spent mowing weeds in City right-of-ways.

PARKS / OTHER – Irrigation demand stayed high with the continued dry and hot weather. After trying several alternatives we finally determined the irrigation pump for Sandy Bluff Park needed to be replaced. A new pump was ordered and will be installed in August. The new Parks Seasonal Worker position was filled and started work on July 1. The focus for this position has been to catch up on a backlog of work at all parks and and help prep and clean up Meinig Park before and after the Mountain Festival.
