Stormwater Quality

During and after every heavy rainfall or storm event, surface runoff washes away loose sediment, chemicals, trash, pet waste, and every other pollutant that the rainwater can carry. This is how surface runoff gets polluted. Polluted water is then carried downstream and ends up in desert washes or detention-retention basins, or seeps underground and adversely affects our fragile desert environment. 

Pima Association of Governments’ Stormwater Program coordinates stormwater pollution prevention outreach on behalf of its member jurisdictions through its annual Clean Water Starts With Me campaign for the public and through a semi-annual seminar for the construction industry. The annual outreach and education helps jurisdictions and the construction industry meet state and federal regulatory requirements.

Responsible stormwater management practices conducted today will help achieve a more sustainable future.

Program Coordination

Pima Association of Governments’ Stormwater Management Working Group (SWMWG) meets on an as-needed basis in order to pool resources and coordinate jurisdictional efforts across the region to keep stormwater clean. In addition to local jurisdictions, members include representatives from the building and construction industry, state government, the University of Arizona and Davis-Monthan Air Force Base.

Arizona Pollutant Discharge Elimination System (AZPDES) regulations require that jurisdictions help protect the stormwater quality of the region. In response, the Working Group provides a forum for consistent messaging on stormwater pollution prevention and collaboration on such activities as the annual outreach campaign and construction industry seminar,where members share information on local and permitting requirements and information on best management practices.

Since its inception in 2001, the SWMWG has grown into an important forum for planning, program development, information exchange, regulatory updates and cooperative projects. The group and its joint activities also provide networking opportunities for planners, outreach personnel, regulators and inspectors.
