Why does stormwater quality matter

  • The storm drainage system is designed to collect stormwater - rain and snowmelt - and release it directly into the Colorado River.
  • Pollutants, such as fertilizers, pesticides, oils and other sediments are transported in stormwater as rain and snowmelt travel across lawns, roads, parking lots and other surfaces.
  • This polluted stormwater then enters the Colorado River without filtration or treatment.
  • Contaminants that enter the stormwater system degrade the quality of our drinking water and pollute our fish and wildlife habitats.

How you can help

  • As good stewards of the Colorado River, we must take extra precautions to ensure that stormwater runoff does not jeopardize the quality of our natural water source.
  • Implementing Best Management Practices (BMPs) and reviewing waste management systems will help ensure a safe work environment and provide a cleaner water source for years to come.
