The Brewerton storm where the pumps lost, and what it teaches
The most useful thing on the public record about wet basements here is not about sewers at all. The Town of Cicero annex to the county hazard plan describes a storm producing up to six inches of rainfall in a short time over urbanized land in which many homes in the Brewerton area experienced significant basement flooding because sump pumps could not keep up with the inflow. That is groundwater outrunning a pump, and the answer is pump capacity, a second pump or a battery backup, not a drain repair. Sewage returning through a floor drain is a different event with a different fix, and telling them apart in the first hour saves the wrong quote.

What sewer backup involves


Pump capacity or pipe fault: deciding it in Cicero
Weigh what the water looked like and where it entered. Clear water rising near a sump pit or seeping at the floor and wall joint during heavy rain is groundwater, and the town's own annex names Cicero Swamp at Route 298 Rattlesnake Gulch, Beach Road, Mud Creek at Hogan Road, Jemola Runne and Cicero Mills, Kathan Road backyards, properties on Route 11 backing the Interstate 81 corridor and Vistula Road as prone to flooding. Foul water coming up through the lowest fixture is the sanitary side. Then weigh the item the county puts on its own prevention list that costs almost nothing to check: sump pumps, roof drains and gutters wrongly connected into the sanitary sewer.
Clear water near the pit is a pump problem
The county's record for this town is explicit that pumps could not keep up with inflow during a fast six inch rainfall. Capacity, a second pump and a backup power source are the work that answers it.
Foul water at the lowest fixture is a sewer problem
Sewage returning through a floor drain, tub or first floor toilet is the sanitary line, and the EPA's list of causes runs from grease and wipes through roots and leaky sewers to wrongly connected sump pumps and roof leaders.
Check the connections before the next storm, not during
A sump pump or gutter plumbed into the sanitary sewer is on the county's own causes list and is usually found in an afternoon. It is the cheapest thing on this page.
Six inches of rain, the named flood areas, and the causes list
The Town of Cicero annex to the 2025 county hazard mitigation plan records a storm producing up to six inches of rainfall in a short time over urbanized land, in which many homes in the Brewerton area experienced significant basement flooding because sump pumps could not keep up with the inflow, and flooding of local roads and drainage systems lasted several hours. The same annex names Cicero Swamp at Route 298 Rattlesnake Gulch, Beach Road, Mud Creek at Hogan Road, Jemola Runne and Cicero Mills, Kathan Road backyards, properties on Route 11 backing onto the Interstate 81 corridor, and Vistula Road as prone to flooding in heavy rain.

WEP names three causes of basement backups: blockages in the sewer line, inflow during heavy rainfall overwhelming the sewer system, and tree roots infiltrating sewer pipes. Its published prevention steps are to keep fats, oils, grease and wipes out of the drain, to check for sump pumps, roof drains and gutters wrongly connected to the sanitary sewer, to eliminate or redirect an unneeded basement sewer connection, to plug or fit a one-way device to a basement floor drain that connects to the sanitary sewer, and to have a licensed plumber install a backwater valve, which must be inspected and cleaned regularly. The department warns that while a backwater valve is holding back a surcharge it is also stopping flow from leaving the house.

The EPA lists the causes of sanitary sewer overflows as inappropriate materials sent to the sewers including fats, oils and grease and products marked flushable such as baby wipes and sanitary pads; tree roots entering through defects or openings in a sewer line; leaky sewers admitting stormwater, groundwater and snowmelt through cracks and faults; inappropriate connections of sump pumps, roof leaders, foundation drains and area drains; improper or inadequate maintenance and cleaning; inadequate pump maintenance; undersized sewers and pumps; and equipment failures and breaks. It also states that where basements flood with sewage the damaged area must be thoroughly cleaned and disinfected and that rugs, curtains, flooring, wallboard and upholstered furniture that contact sewage usually must be replaced.

What Cicero owners ask after a basement takes water
How do I tell groundwater from a sewer backup in a Cicero basement?
Start with where it appeared and what it looked like. Clear water arriving near the sump pit or along the floor and wall joint in a downpour is groundwater, which is what the town's own hazard record describes around Brewerton. Discolored water with an odor rising through a floor drain or a tub is the sanitary line. If in doubt, photograph it before cleanup, because the answer is much harder to reconstruct afterwards.
Will a bigger sump pump stop it happening again?
If the event was inflow beating the pump, capacity is exactly the right conversation, and so is a second pump and a battery backup for the power cut that often comes with the same storm. If the water was sewage, a bigger pump does nothing at all, which is why the two have to be separated before anyone spends money.
