When it rains in the City of Chandler, where does stormwater go?
When it rains in urban areas, the stormwater runs off 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, washes and lakes within the community.
Is stormwater treated?
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, washes and lakes within the community.
In order to protect the quality of stormwater runoff, the City of Chandler obtained a permit from the Arizona Department of Environmental Quality in March 2003. The permit requires the City of Chandler to implement a number of Best Management Practices (BMP's). Some of these BMP's include:
In addition to these BMPs, the City of Chandler has nuisance (Chapter 30) and stormwater (Chapter 45) sections of code, that address discharges of pollutants into the storm drain system.
