The Public Works Department provides a wide variety of services to the citizens of Colfax. These include the areas of transportation, water and sewer services, flood control and storm drainage. Revenue to support the Street Fund is derived from a percentage of the sales tax and property tax the City receives. This fund provides for operation and maintenance of the surface water collection system and the concrete flood control channel.
Revenues come from the monthly storm drain fund paid by residents.
Revenues are generated from user fees based on actual water consumption. This fund pays for operation and maintenance of the sewer system and funds the maintenance of the sewer collection system which includes lift stations, siphons and piping. It also funds the Wastewater Treatment Plant and the lab. Revenues come from user fees. The fee for each customer service is determined by that service's winter water consumption.
