Jamesville Reservoir is one of only six named waterbodies in the county where a failing septic system attracts state replacement money. A Jamesville homeowner within 250 feet of it should apply through the Health Department before paying for a replacement outright.

Questions Jamesville owners ask about backups and septic grants
How do I know whether my Jamesville house is on the public sewer?
Look for the sanitary sewer unit charge on your Onondaga County real property tax bill. The county bills that charge to properties in the Consolidated Sanitary District that are connected to public sewer, with a single-family home assessed one unit, and properties on private septic are not billed at all. It is a faster and more reliable answer than looking for a cleanout in the yard.
Where does sewered Jamesville drain to?
To the Meadowbrook-Limestone Wastewater Treatment Plant at 7530 Manlius Center Road, completed in 1973, which serves sections of DeWitt, Manlius, Pompey and Syracuse. The county's sewer consolidation program currently has an inflow and infiltration abatement project across that service area, lining sewers and replacing and rehabilitating manholes to reduce excessive wet weather flows.
Why is the Jamesville pump station a concern for my basement?
Because it is the outlet. The county's hazard modeling puts the Jamesville Pump Station at 6660 East Seneca Turnpike in both the 100 year and 500 year floodplain with modeled structure damage of 38.0 percent, the highest of any wastewater facility named in the DeWitt annex. A station out of service does not send water to your house, it takes away where your house sends water.
Does Jamesville Reservoir qualify for septic replacement funding?
It is one of the six named waterbodies. The Onondaga County Health Department administers New York's Septic System Replacement Funding Program for properties within 250 linear feet of Skaneateles Lake, Skaneateles Lake's tributaries, Otisco Lake, the Seneca River between the Cross Lake outlet and Klein Island, Jamesville Reservoir, or Rush Creek Upper and its tributaries, where the owner has a substandard or failing septic system.
Backflow, drain and septic work we arrange in the hamlet
Drain cleaning
Some Jamesville homes are on the public sewer and some are not, and the tax bill settles it in about a minute. That answer changes what a slow drain is likely to mean.
Main line cleaning
Sewered Jamesville feeds a plant the county is actively relining to keep stormwater out. Whether that has reached your street changes what a lateral cleaning is really solving.
Backup crew
Everything sewered in this hamlet leaves through one pumped facility, and the county models it at the highest structure damage of any wastewater facility in the DeWitt annex.
Camera and repair
Jamesville Reservoir is one of only six waterbodies in the state program, so a failing tank near it has a funding route to check before anyone writes a replacement quote.

One pumped outlet, and what it means for a Jamesville basement
In a large flood a Jamesville property should expect the sewer to be unavailable rather than merely slow, which is the case a backwater valve is bought for.
Jamesville is a hamlet in the Town of DeWitt and its sanitary flow leaves through one county facility: the Jamesville Pump Station at 6660 East Seneca Turnpike, which the county's own hazard modeling places in both the 100 year and the 500 year flood with 38.0 percent structure damage, the highest of any wastewater facility named in the DeWitt annex.
Read that as an outlet that can be unavailable rather than merely slow.
- The code test for protecting a basement is a comparison of two elevations, not an opinion: section P3008.1 of the New York residential code requires a backwater valve in the building drain, a branch of it, or the horizontal branch serving any fixture whose flood level rim sits below the cover of the next upstream manhole in the public sewer, and section P3008.4 requires the working parts to stay accessible.
- Water Environment Protection adds the part people miss: while a valve is holding back a surcharge it is also stopping flow leaving the house, so it comes with a household rule as well as a fitter.
- Sewered Jamesville drains to the Meadowbrook-Limestone plant on Manlius Center Road, where the county has an inflow and infiltration abatement project relining sewers and rehabilitating manholes to reduce wet weather flows.
- And for anyone here not on the public sewer, Jamesville Reservoir is one of only six waterbodies in the county named in New York's Septic System Replacement Funding Program: a property within 250 linear feet of it with a substandard or failing septic system should apply through the county Health Department before paying for a replacement outright.
