Management Program

The Stormwater Management Section (SWM) works in cooperation with other City departments to coordinate the City's stormwater management program and maintain compliance with the Municipal Separate Storm Sewer System (MS4) permit. SWM inspects industrial and commercial facilities for compliance with Phoenix City Code Chapter 32C, investigates illicit discharges to the storm drain system, conducts wet-weather monitoring, and conducts public outreach.  The Street Transportation Department is responsible for maintenance of storm drains and washes, cleaning the streets and catch basins, as well as creating maps of the City's storm drain system. The Planning and Development Department monitors construction sites for stormwater compliance. Public Works implements the Household Hazardous Waste Collection Program and works with Keep Phoenix Beautiful to conduct environmental education and outreach programs. The Office of Environmental Programs coordinates city employee training and evaluates City facilities and construction activities for compliance with stormwater requirements.
