What is Stormwater?

Stormwater pollution can impact our surface waters which directly impacts the source of our drinking water.  Water is a staple in our daily lives. We use it for drinking, washing our clothes, showering, watering our lawns and more.  As pollution continues to impact drinking water supplies, there will be continued efforts to test and treat contaminants, leading to increasing prices for clean and safe drinking water.

What can pollute Stormwater?

Industrial - Land uses that are involved in manufacturing, production or transportation, including construction activities.  Waste generated at an industrial site, when exposed to rain or outdoor watering, can wash into rivers, streams and lakes.

Residential - Residential areas and neighborhoods can significantly impact rivers, lakes and streams due to polluted stormwater runoff. Improper disposal of yard clippings, fertilizer, pesticides, and herbicides can lead to the exposure of excessive nutrients can discharge into receiving waters (lakes, rivers, streams, and creeks).  Washing your vehicle on the driveway or street allows a perfect opportunity for the soapy water and other cleaning chemicals to make their way down the street into a storm drain and the nearest stream. The household hazardous wastes in and around your home can affect your family and pets and can be toxic to fish and wildlife. A simple solution to water pollution is picking up after your dog. When it rains, your pet's "business" is washed down into the street and storm drain contaminating our rivers, lakes and streams with unhealthy levels of bacteria.

Institutional - Institutions such as schools, universities, hospitals, churches and government facilities can cause water pollution in the same way that businesses and residents can generate it. The types of waste are similar to that of any home or work environment and if not disposed of or managed properly can cause adverse effects on the environment.

Commercial- Involves businesses that are retail oriented or perform services for customers.  Examples include auto service shops, gas stations, restaurants and lawn care services. Motor oils, antifreeze, oil filters and cleaners can be potentially harmful to the environment if not recycled.


How Stormwater Is Carried to Surface Waters?
Stormwater runoff may be carried through natural or manmade drainage ways or conveyance systems.  In some cases stormwater runoff leaves a site spread out over a large dispersed area as “sheet flow.”  It may also be conveyed through natural ditches, swales and natural drainage features.   In most developing and urbanizing areas, stormwater is conveyed through a system of catch basins and pipes commonly referred to as a storm sewer system. 

What is considered Impervious?

Impervious surfaces are those areas that prevent rainfall from infiltrating into the ground. Examples of typical impervious surfaces found on most properties include rooftops, driveways, sidewalks, patios, parking lots, storage sheds, etc. 

What is the purpose of the Stormwater utility?
The purpose of a stormwater utility is to provide dedicated funds specifically to the City of Canton’s Stormwater Management Program.

How are Stormwater utility fees calculated?
Stormwater utility fees are calculated based on the amount of impervious surface of each property.  

How is my bill calculated?
Your bill is calculated of the total square footage of impervious area on your property.


Fee = IR x IU 
      IR =     Impervious Area Rate - $2.65 (Billing Rate)
      IU =    Impervious Runoff Unit @ 2,000 square feet for commercial

(first unit up to 3,999 sq. ft. impervious area, with a $5.30 capped fee for residential)
