Title

03-4J550 Truckee Wash Rack Sewer Connection

Description

The California Department of Transportation (Caltrans) proposes a maintenance project at the Truckee Maintenance Station (MS) in Nevada County. The project proposes to connect the existing wash rack to the municipal sewer system The scope of work includes creating a trench drain to collect wash water and installing an electrical diversion valve and a sand-oil separator. The three-way valve would be installed at the outlet of the trench drain and would determine whether the discharge from the wash rack goes to the storm drain or the sand-oil separator. When the was rack is in use for a vehicle wash, the valve would divert the wash water to the sand-oil separator and then to the sewer system.When the wash rack is not in use, the valve would direct stormwater to the storm drain. Additionally, a sampling port would be installed so maintenance staff can collect samples of the wash water entering the sewer system.
