The Stormwater Division is responsible for maintaining 75 miles of storm pipes, catch basins, city-owned ditch lines and creeks throughout the City. Stormwater is water from rain, snow, sleet, hail, that flows across the ground and pavement or when snow and ice melt. The water seeps into the ground or drains into what we call the storm drain system. These are the drains you see at street corners or the low points on the sides of streets managing stormwater - both drainage and pollution - and they are an integral component of a comprehensive public works package. Inadequate stormwater management can result in flooding, infrastructure and property damage, excessive soil erosion, degraded open space, and polluted water quality leading to problems in the public water supply and other water bodies.

The primary function of storm water drainage systems, including natural channels, is the collection, conveyance and storage of stormwater runoff. In a watershed-based approach to urban stormwater management, the municipal separate storm sewer system, or MS4, including both structural (e.g., pipes, inlets, and outlets) and natural drainage ways, is a critical structural component. Illicit Discharge (i.e., any discharge that is not composed entirely of stormwater) Control is a major component of a stormwater system. Click here to learn more about MS4.

Stormwater Utility User Fees

Like the City's water and sanitary sewer utilities, the Stormwater Utility is self-supporting. Revenue collected from Stormwater Utility user fees goes towards stormwater management, which includes fees to cover the expenses to meet obligations under the NPDES Stormwater Regulations and to pay for the operation, maintenance, and capital improvements of the City's stormwater infrastructure. The Stormwater Utility also works to solve and prevent drainage problem, and repair, maintain, and enhance drainage facilities. Ideally, residential, commercial, industrial, institutional and governmental customers should pay for their water and wastewater service based on their relative system use. The most equitable method to pay for stormwater service is to look at each property's relative use by analyzing the impervious and pervious areas of each. This way, contributors to the stormwater runoff pay their fair share.

For billing efficiency, residential properties are billed a flat monthly rate based on pervious and impervious measurements from an average residential property. Under the City's Stormwater Utility rate structure, residential properties will be billed $5.75 per Month, based on 2,611 Sq. Ft. or 1 ERU (Equivalent Residence Units). All non-residential properties are billed monthly, based on a stormwater user fee calculated specifically, based on the impervious measurements of their property divided by 2,611 which equals ERU’S times $2.50.

Illicit Discharges - What You Need To Know
Why Does The City Need to Control Illicit Discharges?
 The Great Miami River is a prominent feature and tremendous natural resource for our City. Historically, it is why the City of Franklin even exists and it continues to sustain us by providing a high-yielding aquifer used as our drinking water source. The Great Miami is also where the City's stormwater runoff (rain that does not soak into the ground) ends up....whether by creek, open channel, or storm sewer system....when it rains in Franklin, stormwater runoff flows into the Great Miami River. Therefore, keeping the stormwater runoff as clean as possible is important to protect this vital natural resource. In the spirit of protection, the City, in cooperation with the Ohio Environmental Protection Agency, has adopted an "Illicit Discharge and Illegal Connection Control" Ordinance [PDF]. The ordinance prohibits the discharge of pollutants into the City's storm sewers, creeks and Great Miami River, and prohibits sanitary service connections into the storm sewer system.
What Is An Illicit Discharge?

An illicit discharge is any discharge into the City’s stormwater system that is not composed entirely of stormwater.

Common Illicit Discharge Pollutants: Motor oil, anti-freeze, cooking oil or greases, cleaning chemicals, paints, varnishes, pesticides, fertilizers, sewage, excessive grass clippings, animal waste, and general litter (trash).

What Am I Prohibited From Doing?
You should not discharge, or cause to be discharged, any illicit discharge into the City's storm sewer system or creeks. In other words - and to play it safe - do not dump any chemicals, waste, or trash into a storm sewer inlet, drainage channel, or creek. Use pesticides and fertilizers sparingly. Also, you should not have an illegal connection (such as a sanitary sewer) connected into the storm sewer system.
What Happens If I Violate the Ordinance?
 If the City becomes aware of a violation, it will first serve a Notice of Violation/Correction Order to the person or property owner that is in violation. This will provide an opportunity for corrective action to be taken by the person or property owner without any penalties. However, if the Correction Order is not complied with in the time allotted, penalties may result, including criminal prosecution and fines of up to $1,000 per day.
What You Should I Do If I Witness An Illicit Discharge?

If you think you have witnessed an illicit discharge, or are aware of one taking place (or that has previously taken place), please report it to the City of Franklin Public Works Department at (937) 746-5001 or at sinman@franklinohio.org so the matter can be looked into.

Please contact the City of Franklin Public Works Department if you have any questions regarding the City’s Illicit Discharge Control Ordinance. Again, the goal of this ordinance is to protect the City's creeks and the Great Miami River for the benefit of the entire community, so please do your part. Thank You!
