PROJECT DRY BASEMENT

Our sewer backflow prevention program, known as Project Dry Basement, began in 2020. It is a something an owner of property can do to mitigate against water in their basement during wet weather events or blockages that cause surcharge of the sanitary system. This program will cover will not cover the cost of a suggested backflow prevention device.  

After reporting the basement backup (must be reported as soon as possible to the Wastewater Department at 614-402-9875), if your property is verified to be eligible, you will receive an evaluation form in the mail. For information about the program, please view the Project Dry Basement fact sheet (PDF file using Adobe Acrobat Reader). ^*If you would like to file an online report to see if you qualify for a backflow prevention device, please apply here Wet Basement and Neighborhood Flooding Questionnaire.   

Stormwater Capital Improvement Projects are developed to solve neighborhood surface flooding problems. Please report any street flooding to the Service Maintenance Operations Center by calling 740-601-5650. If the crew cannot find a blockage or issue they can address, please complete and submit a Wet Basement and Neighborhood Flooding Questionnaire for capital improvement project consideration.

Backflow Prevention Device Maintenance Information

Once installed in your home, the device must be maintained to ensure it remains in proper working condition. Please follow these maintenance instructions:

Manufacturer recommends once a year the homeowner manually open and close the valve three (3) or four (4) times to exercise the bellows in the valve housing. This is accomplished by inserting the maintenance T-handle through the hole located in the center of the top of the valve cover and attaching to the threaded stem located on the top of the counterweight top. Once attached, pull the handle up slowly until it stops. Release the handle and allow it to return to the original position. Repeat this action for three (3) or four (4) cycles.

The manufacturer of the backflow valve advises periodic inspection and cleaning (monthly is suggested) of their product.

Please follow these instructions:

• Remove the lid cover from the pit.
• Unscrew the four-inch round clean-out plug on the top of the valve box and do a visual inspection.
• Shine a flashlight or trouble light into the hole to see the valve body.
• Inspect for debris build-up on the body, gate and beneath the gate.
• If debris build-up is found, flush clean with a water hose and sprayer.
• Ensure gate freely moves up and down.
• Reinstall clean-out plug (do not over tighten) and pit lid cover.

Following the above instructions for your specific backflow prevention device will help to ensure that your backwater valve is in proper working condition to protect you from sanitary sewer backups.
