The city of Glendale is considered a Phase I Municipal Separate Storm Sewer System (MS4). This means that the storm drain system is separate from the sanitary sewer system. Stormwater that does not soak into the ground or evaporate gets discharged into Skunk Creek, New River or the Agua Fria River. Unlike water and wastes conveyed in the sanitary sewers, stormwater is untreated before being discharged.
Glendale maintains a Stormwater Management Program (SWMP) that is designed to reduce pollutant discharges to and from the city’s municipal storm sewer system. The program includes the following:
- Current MS4 Permit from the Arizona Department of Environmental Quality
- Stormwater Enforcement Response Plan
- Most recent Stormwater Annual Report
