We were in compliance with our discharge permit for the month of October. Effluent BOD and SS limits do not apply when the treated wastewater is used for land application these figures are shown to demonstrate treatment efficiency.   2.5 dry tons of sludge were processed and spread on local pasture land.  Two pumps at the treatment plant failed, were taken in for repair and returned to service during October. The Southside pump station at Arletha and Cascadia Village Dr. serving the Snowberry subdivision was placed into service.

STREETS – The street sweeping contractor spent 62 hours sweeping streets and collected 48 tons (77 cu. yds.) of debris, covering 259 lane miles. City crews used 5 tons of asphalt patching potholes and utility cuts. The dry weather in October allowed the developer’s contractor to complete paving and striping on the project widening Hwy 211 at Village Blvd.

PARKS / OTHER –  Parks staff took advantage of the dry October weather to catch up on fertilizing and seeding of areas that were too wet in September. PW staff began cleaning catch basins and storm drainage pipes in anticipation of winter rains.
