Welcome to the City of Sioux City Public Works Department Website!


The City of Sioux City Public Works Department provides many of the basic services that affect the daily lives of everyone who lives and works in Sioux City. Primarily, the Department is responsible for all the things we take for granted on a daily basis: the administration, planning, maintenance, construction management and technical engineering of the City's infrastructure. This includes the distribution of water and collection of waste water, the maintenance of the City's streets, storm water infrastructure, street name and traffic control signs, and traffic signals, just to name a few.

The responsibilities of the Public Works Department are distributed among three divisions, they are: Engineering Division, Parks and Recreation Services, and Field Services.
