The Water and Sewer Division is responsible for the operation and maintenance of the water distribution and sewer collection systems for the City. The City installs and maintains water meters, fire hydrants and maintains the sanitary and storm sewer systems. The City now maintains a total 150.8 miles of sanitary sewer lines, 170.4 miles of water lines and approximately 136.6 miles of storm sewer lines.  Water and sewer services are purchased from the City of Columbus, with billing to the residents’ of Gahanna processed through the Gahanna billing office.

The staff for the Water and Sewer Division consists of one foreman, seven equipment operators, three full time account clerks and seasonal employees as needed.  They are responsible for meter reading, water line and sewer service inspections, water meter setting, final meter reading, pump station maintenance, field spotting of underground water, sewer and street lines, sanitary sewer cleaning, catch basin cleaning, fire hydrant maintenance including installation, flushing and repairs as well as response to emergency situations, such as water line breaks or sewer back-ups.

The City of Gahanna is classified as a satellite community because it does not treat its own wastewater.  The Ohio EPA has ordered all satellite communities operating a wastewater collection system to implement a capacity management operations and maintenance (CMOM) program to manage collection system assets and ensure compliance of best management practices developed by the industry. Therefore, the City of Gahanna is required to implement its own CMOM program.  Click here for more information.

It is important for residents who are not tied to the City’s sanitary sewer system to properly maintain their HSTS. Click here for information on the operation and maintenance of home sewer treatment systems.

Low water pressure could be caused by a variety of reasons. It could be a water leak or a bad meter. Before calling a plumber, call the City of Gahanna so we can make sure it is not something for which the City is responsible. Call 614-342-4440, Monday thru Friday, 8:00 am - 5:00 pm. After 5:00 pm and on weekends and holidays, call 614-342-4240.

The City is responsible for water leaks from the curb box (located in the front of the property, near the sidewalk) to the water main and the mains themselves. The homeowner is responsible for the water line from the curb box to the house. If you suspect a water break, call the City and we will determine whether the City or the property owner is responsible for the repairs. Call 614-342-4440, Monday thru Friday, 8:00 am - 5:00 pm. After 5:00 p.m. and on weekends and holidays, call 614-342-4240.

Frigid temperatures can lead to frozen water pipes and costly plumbing repairs.  Depending on the diameter of the pipe it can take only a matter of hours to freeze.  This can then cause the pipes to burst.  Take the following precautions to protect your pipes:

  • Insulate water lines in unheated areas of your home (ie: garage, attic, basement, crawl space, etc)
  • If pipes are vulnerable to freezing (such as those located on an exterior wall), let the faucet drip to keep the water moving through the pipes.  The cost of the extra water is low compared with the cost to repair a broken pipe
  • Keep cabinets or vanities open to expose pipes to warmer room temperatures
  • Detach outdoor hoses from faucets (this allows connecting pipes to drain)
  • Know where the master shutoff valve is located (typically where the water line comes into the home from the street)

During an extended and extreme cold period, pipes may freeze despite taking the precautions listed above.  Using a low setting on a hairdryer is the safest way to thaw a frozen pipe.  Wave the warm air back and forth along the pipe rather than concentrating on a single area.  If a hairdryer is not available, wrapping the pipe with towels and pouring hot water over them is another option.  Never use a torch with an open flame to thaw a frozen pipe.  This could cause a fire or overheat a section of the pipe and cause it to leak or burst.

If your pipes burst due to freezing temperatures (or you have an unknown water leak inside your house), follow the steps below:

1. Shut off the water line into your house at the master shutoff valve.  This is typically located before your water meter (where the water line comes into the home from the street).  This will stop the water from flowing out of the leak.
2. If the water is still flowing from the leak after turning the shutoff valve, call the City of Gahanna Water Division at 614-342-4440.  The City will send out a utility crew to shut off your water from the street tap.
3. Call a plumber to inspect the leak and perform repairs.  A list of plumbers can be found in your local phone book.  The City’s utility crew are not licensed plumbers and cannot perform private water line repairs.

If the water looks or smells bad, do not drink, cook, clean or bathe with it. Contact the City and we will check it out. Call 614-342-4440, Monday thru Friday, 8:00 am - 5:00 pm. After 5:00 pm and on weekends and holidays, call 614-342-4240.

The City is responsible for maintaining the sewer mains. The property owner is responsible for maintaining their sewer laterals, which run from the house or business to the sewer main. If you think you smell sewer gas, do not hesitate to contact the City. The City will check and (if necessary) clear the main. If it is the lateral that is clogged, it is the property owner's responsibility to have their lateral cleared. Call 614-342-4440, Monday thru Friday, 8:00 am - 5:00 pm. After 5:00 pm and on weekends and holidays, call 614-342-4240.

The City is responsible for all sewer basins and lids. If any lid is broken or if you notice any problems with the sewer pits, call 614-342-4440, Monday thru Friday, 8:00 am - 5:00 pm. After 5:00 pm and on weekends and holidays, call 614-342-4240.

Do not cover, bury, or block any sewer pit lid. This makes it very hard to clear backups or run any kind of maintenance. Please make sure we have access to the sewer pits. We will knock before we enter property, but if a fence or other obstructions hamper our investigation, it may cause your basement to backup since time is critical in clearing and cleaning sewer pits.

Sewer adjustment meters, also referred to as deduct meters, keep track of the amount of water used by a property owner that is not taken away via the sanitary sewer (ie: water used to water lawns). It is a water meter that registers outdoor water use.  The water use calculated by a SAM will not be charged sanitary sewer charges. Sewer adjustment meters can be purchased through the Gahanna's water department. An Advanced Metering Infrastructure (AMI) transmitter must also be purchased with the meter. The property owner has the meter installed by a vendor of their choice and then inspected by the City. During inspection, a Gahanna employee will install the AMI transmitter.

If the water from a SAM is being applied to an irrigation system, a backflow prevention device must also be installed. This also requires a plumbing permit. This permit can be obtained from Gahanna's Building Division. Click here to review Gahanna's SAM installation standards.  For a detailed guide on how to install a sewer adjustment meter click here. For more information, call 614-342-4440, Monday thru Friday, 8:00 am - 5:00 pm.

When paying your water bill through your bank’s online bill pay service, please be sure to include all 8 digits of your account number. Errors will cause a delay in payment processing. If you are leaving for an extended period of time, please notify the Utility Billing Division at 614-342-4440, Monday thru Friday, 8:00 am - 5:00 pm, so that your account is noted in case they would need to contact you (ie: water leak, etc).
