The annual wash down of parking garages on the Missouri State University campus must be performed such that there is no discharge of contaminated water into the storm sewers. All wash water must be captured and discharged into the sanitary sewers. No chemicals are to be used in the washing operation. The Springfield Sewer Operations personnel are to be contacted prior to discharging into the sanitary sewers and the amount of water discharged is to be provided to Springfield Public Works department for billing purposes. Billing for the waste disposal should be directed to the Environmental Management Department. Periodic sampling of the wash water may be required by the city.
Park N Ride
A meter is to be connected to the water outlet in the Park N Ride to determine the water usage. Prior to washing, the outlet from the storm box located immediately north of Cherry Street and east of the Park N Ride loop must be plugged to capture the wash water. The wash water will then be pumped across the south entrance to Lot 37 into the sanitary sewers manhole located adjacent to the west side of the driveway.
ITF
A meter is to be connected to the water outlet in the ITF to determine the water usage. Prior to washing, steps will be taken to divert the wash water from the storm sewers into the sanitary sewers. Steps must be taken to re-direct the flow from the sanitary sewers immediately upon completion of the washing operation.
