Environmental Protection

The Water Services Department's Environmental Resources Group provides policy advice, planning services and programs for air quality, drinking water quality, stormwater, water conservation, water resources, and other environmental issues. The group assists the city with conducting its operations in an environmentally-responsible manner and provides corporate-level guidance to create an organizational culture that strives for high-level and continual improvement in environmental stewardship and performance.

Air Quality

Breathing clean air is necessary fora healthy life. In order to protect human health, the Environmental Protection Agency (EPA) establishes air quality standards that states and municipalities, like the city of Glendale, must meet. The Arizona Department of Environmental Quality (ADEQ) and the Maricopa County Air Quality (MCAQ) Department also regulate air quality in the state and city.

City of Glendale Dust Ordinance

State law requires Maricopa County and the city of Glendale, along with other cities and towns, to adopt and enforce dust control requirements to help make the air cleaner for our community. The county regulations and Glendale city ordinance outline the dust control responsibilities that fall to both commercial and residential property owners. For more information on the city's requirements or for enforcement, call the city of Glendale Code Compliance Department at (623) 930-3610.

Stormwater

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)(PDF, 7MB) that is designed to reduce pollutant discharges to and from the city's municipal storm sewer system. The program includes the following:

To provide comments or questions on the city's Stormwater Management Program:

What happens in the watershed stays in the watershed! As rain falls on the ground, it picks up fertilizers, pesticides, pet waste, oil and other chemicals. This contaminated stormwater eventually travels into our washes and waterways.

Stormwater Outreach for Regional Municipalities (STORM) is a regional non-profit organization promoting stormwater quality education within the Phoenix metropolitan area. STORM was funded in response to federal regulations requiring municipalities to educate the public on ways to protect the quality of stormwater runoff.

Sanitary Sewer

Fats, Oils, and Grease

Rethink what goes down the sink! Fats, oils, and grease (FOG) poured down your kitchen drain can solidify in your pipes and cause sewage to back up into your house.

Help prevent sewage blockages by:

  • Pouring used grease into a sealable container and disposing in the trash.
  • Scraping food from dishes and cookware into the trash before washing.
  • Putting a strainer over the drain to catch food scraps and disposing of them in the trash.

Disposal of Unused Medication and Personal Care Products

Don't rush to flush! The once common practice of discarding of unwanted medications down the toilet or sink is no longer acceptable because many medications cannot be broken down at a water reclamation facility. There are several alternatives:

  • Option 1 - Keep unused medication in its container and place it into a MedReturn Box at the following Glendale Police stations: Foothills (6255 W. Union Hills Dr.) and Gateway (6261 N. 83rd Ave.).
  • Option 2 - Put your unused medication into a sealable bag or container and mix with an undesirable substance (kitty litter or used coffee grounds). Dispose of in the trash.
  • Option 3 - Contact your local pharmacy to see if they collect unused medication.
