City Wide Downspout Disconnection Program
In an effort to reduce the amount of storm water that enters Marion's sewer system when it rains, the city is continuing Marion's downspout disconnection program. In past years there have been organized initiatives that verified the disconnection of downspouts and sump pumps from the sewer system. This current phase of the program ask Marion's citizens to continue to partner with the city to improve water quality, protect our homes from flooding, and reduce operational cost to the city.
Rainwater that enters the city's sanitary and combined sewer system takes up valuable capacity in the sewer lines. When storm water rapidly enters the combined sewers the system can become overloaded resulting in the discharge of combined sewage to the Mississinewa River. Excessive amounts of storm water entering the city sewer system can also result in flooding of streets and homes.
Why should I disconnect?
Combined sewer overflows discharge when the volume of rainwater or snow melt entering the combined sewer system causes the combination of sanitary sewage and rainwater in the system to exceed the capacity of the pipes that carry waste to the waste water treatment plant.
The points in the combined sewer system designed to relieve this excess capacity are CSO discharge points. During significant rain events combined sanitary sewage and rainwater is discharged to the Mississinewa River at these locations.
By eliminating as many sources of inflow as possible you are helping to protect the water quality of the Mississinewa River and protecting your family and property from possible sewer backups and overflows. Also, the reduction of storm water to the sewer collection system results in decreased maintenance and operational cost for the City of Marion.
When downspouts and sump pumps are disconnected from the sewer both the amount of storm water and rate that storm water enters the sewer system are reduced. Part of the water from these disconnections will infiltrate into the ground and never enter the sewer system. The part of the water that does run off of our yards and enters the sewer system through a catch basin does so much slower than water from a direct connection. The reduction in storm water volume combined with the delayed entry of storm water into the sewer system assist in reducing the number of times the sewer system becomes overloaded.
Am I required to disconnect my downspouts from the sewer?
In addition to providing many benefits to the community, disconnection of downspouts and sump pumps is required by the City of Marion. A City Ordinance is currently under review that specifically prohibits the connection of downspouts and sump pumps to the sanitary or combined sewer system.
How can I learn more?
Additional information about the city's downspout disconnection program can be found on the City of Marion Storm Water Website Marion Utilities Department or you may request a hard copy of the information found on the website by contacting Marion Utilities Department at 765-664-2391. Information on the website includes detailed downspout disconnection instructions, a copy of the downspout disconnection compliance form, and general information about the program.
Please help us to keep our waterways clean, protect our homes and reduce cost.
