As part of routine winter maintenance activities, salt trucks are washed frequently at the Ohio Department of Transportation’s (ODOT) 88 county and 136 outpost garages during the winter months. In locations where sanitary sewer is available, truck wash water is treated with an oil/water separator and discharged directly to the sanitary sewer system. However, at facilities that do not have access to sanitary sewer, truck wash water must be collected and managed, often at a significant cost. The current ODOT policy for truck wash water management, tying these facilities into the sanitary sewer system, has a high capital cost, and is not always possible. The purpose of this research was to identify alternative strategies for managing wash water generated during routine washing of salt trucks at ODOT maintenance facilities lacking access to sanitary sewer, assess their costs, and compare the cost of alternative management strategies with the cost of tying into the sanitary sewer system. Six viable wash water management strategies were identified and the annualized costs of each option were calculated for individual maintenance facilities. The cost analysis indicated that site specific conditions, including the volume of wash water generated, the distance to the potential disposal locations, and the capital cost of tying into the sanitary sewer, directly impact the cost effectiveness of alternative management strategies. Under the conditions of the cost analysis, pursuing off-site disposal, rather than tying into the sanitary sewer, could yield an annual cost savings of approximately $1.1 million across ODOT’s 12 county and 66 outpost garages lacking access to sanitary sewer. The analysis also showed that, for a typical county garage with 12 trucks and 30 winter events, when the capital cost of tying into the sanitary sewer is greater than $300,000, four of the five management alternatives identified are more cost effective than tying into the sanitary sewer.
