What is stormwater? Stormwater is runoff and surface flows generated from rainfall events.
The city's Stormwater Program helps educate the community on environmental regulations. Chandler works with state and federal regulators to make sure residents understand the effects of stormwater drainage and how to reduce pollutants in the storm drain system.
The city offers free presentations about stormwater pollution prevention for schools, community groups, homeowners and neighborhood associations. Call 480-782-3503 for information.
Feedback Requested for Stormwater Program
The City of Chandler is required to prepare and maintain a Stormwater Management Program (SWMP) to ensure the city complies with state and federal regulations. Stormwater is the runoff generated from rainfall. When it rains in urban areas, stormwater runs off buildings and paved areas instead of soaking into the ground. The city’s storm drain system is designed to move that stormwater along conveyances like city streets and gutters where it is directed into storm drains or spillways constructed along the street. Eventually, this stormwater is deposited into retention basins, greenbelt areas, parks and lakes within the community. The city’s SWMP is meant to help residents understand how the city manages stormwater and to educate them on what they can do to reduce pollutants entering the storm drain system. It’s important to get feedback from Chandler residents to learn where the program improvements can be made. The city is asking residents to participate in the review and implementation of the SWMP. Access the below and submit your comments to Environmental Management. This announcement starts a 30-day public comment period. The City will then compile the comments, and use them to assist with revising and improving the SWMP. |
When it rains in urban areas, the stormwater runs off buildings and paved areas instead of soaking into the ground. The stormwater collection system, also known as the storm drain system, is designed to move stormwater flows along conveyances like city streets and gutters where it is directed into storm drains or spillways constructed along the street, and eventually deposited into retention basins, greenbelt areas, parks and lakes within the community.
No. The stormwater collection system is completely separate from the sanitary sewer system connected to our homes and businesses. The sanitary sewer system delivers wastewater from our sinks, showers, toilets, and washing machines to a wastewater treatment facility where the wastewater is treated and either reused or recharged to groundwater. Stormwater runoff collected in stormwater collection systems is not treated before it infiltrates to groundwater or is discharged to retention basins, greenbelt areas, parks and lakes within the community.
Common pollutants found in stormwater may include but are not limited to, pesticides, fertilizers, litter, pet waste, petroleum products, automotive fluids, paints, solvents, yard waste, sediment, chemicals, and other materials.
Report flooding, stormwater issues, illicit dumping/discharge, standing water or pool drainage.
