Program Summary

When rain falls in the City of Mesa, runoff water is collected by many different types of inlets. The water is then routed via curbs/gutters, pipes, open channels and other conveyances to community retention basins, parks, local lakes and rivers and area floodways. The runoff does not go to a treatment plant.

The City of Mesa operates a municipal storm sewer system under a permit issued by the Arizona Department of Environmental Quality. That permit requires Mesa to implement a number of different programs called Best Management Practices (BMPs). Some of these BMPs include:

  • Retention Basin Maintenance
  • Storm Drain Maintenance
  • Street Sweeping
  • Spill Response
  • Household Hazardous Waste Collection
  • Public Education
  • Hazardous Materials Response
  • Oversight of Industrial Facilities
  • Support of Oil Recycling
  • Oversight of Construction Sites
