City of Houston

Houston Public Works provides many of the basic services that affect the daily lives of everyone who lives and works in Houston. 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 production and distribution of over 146 billion gallons of water per year and the treatment of over 90 billion gallons per year of wastewater. That is enough to fill the Astrodome four times per day with fresh water and over twice per day with wastewater. It also includes the maintenance of the City's over 16,000 lane miles of streets, over 60,000 stormwater manholes, over 100,000 stormwater inlets, over 1,100,000 street name and traffic control signs, over 17,000 freeway and under bridge light fixtures, over 50,000 fire hydrants and traffic signals at over 2,450 intersections.
