MSD Sewer Connection Credits
Under Ohio EPA policy, for every new gallon of sanitary sewage added to MSD's combined sewer system, four gallons of storm water must be removed. For every new gallon of sanitary sewage added to MSD's sanitary sewers, five gallons of storm water must be removed.
MSD uses a system of connection "credits" to manage sewer connections under this Ohio EPA policy. Any change that will increase wastewater flow into the sewer system requires a certain number of credits, depending on the amount of wastewater introduced through the new connection. In general, one credit is required for new connections that will generate a flow equivalent to that produced by an average single-family residential home. To obtain one connection credit, an amount of storm water equivalent to the amount of wastewater flow generated by four residential properties must be removed from the system.
MSD creates connection credits by completing sewer improvement projects that increase capacity and flow in the sewer system. MSD then banks its credits and makes them available to developers on a first-come, first-served basis.
Developers can also create credits and apply them toward their own projects.
