DETENTION BASINS AT TWO SNOW REMOVAL MAINTENANCE STATIONS: AN EVALUATION. INTERIM REPORT

The evaluation of two detention basin systems at snow removal maintenance stations is documented. The basins were built as mitigation measures to clarify storm runoff or wash water from maintenance activities that enters nearby streams. The three basin system at the Echo Summit Maintenance Station removed sediment and was effective in reducing turbidity, floatables (oil and grease), and to a lesser extent, chloride. The system has a capacity of approximately 10,000 cubic feet. The riser outlets are fitted with grease rings. The three basin system at the Truckee Maintenance Station did not fill with water during the study. The basins were filled witth sand, and they performed more like a sand filter trap than a detention basin. The capacity of the three basin system is 3600 cubic feet, and there are no grease rings. The water volume from washing trucks does not produce runoff to cause the basins to overflow. (Author)
