Sewer Backup and Basement Flooding Inside the City of Syracuse
First the line comes open and the house drains. Then we settle whether that water was yours or the street's, because on a city floor those two look identical and cost nothing like the same.

Two ways a Syracuse basement takes sewage, and how they differ
Getting the house draining again is the same first job anywhere. What is different inside the city line is the second question, because a Syracuse street carries sewage and stormwater in the same pipe and a surcharge in that pipe puts water into a basement with nothing wrong in the house at all.
The county is spending five million dollars reconfiguring the flow regulator at Evans Street between Maltbie Street and Leavenworth Avenue, excavating to nearly thirty feet with the stated aim of cutting how often CSO 066 overflows, work that began on site in January 2026. Knowing which of the two you had is what stops it repeating next spring.
Checked against Onondaga County Department of Water Environment Protection, Evans Street flow regulator project and Onondaga County Department of Water Environment Protection, Combined sewer overflows (checked September 8, 2026).

What city owners ask while the basement is still wet
Is there a public record of the overflow that flooded my Syracuse basement?
There may well be. New York's Sewage Pollution Right to Know Act requires a publicly owned sewer system to report a discharge of untreated or partially treated sewage, including a combined sewer overflow, to the Department of Environmental Conservation and the local health department within two hours of discovery, and to notify the public electronically within four. Match that to the hour your basement started taking water.
My line was cleared and the basement still floods in a storm. What is left?
In the city, capacity. Sewage and stormwater share one pipe here, and during heavy rain or snowmelt the volume can exceed what that pipe carries. Nothing done to a clear lateral changes a surcharge in the street, so the work that helps is protecting the openings below street level rather than cleaning the line again.
What to establish before the cleanup starts
Weigh the timing above everything else. Water that arrives during or just after heavy rain or a fast thaw, in a house whose drains were fine the day before, behaves like a surcharge in the street. Water that built up over weeks of slow drains behaves like a blockage in your own lateral.
Note the hour it started, photograph the level line, and keep it, because New York's Sewage Pollution Right to Know Act requires the operator of a public sewer system to notify the public through electronic media no later than four hours after discovering a discharge, and that timestamp may line up with yours.
- Write down the hour it started
A public overflow has to be reported to the state and the local health department within two hours of discovery and to the public within four. Your own timestamp is what makes that record useful to you.
- Do not clean up before you have photographed it
The EPA is blunt about what follows sewage contact: the area must be thoroughly cleaned and disinfected, and rugs, curtains, flooring, wallboard and upholstered furniture that touched it usually have to be replaced.
- A city backup has a city phone number
Onondaga County directs City of Syracuse properties to the City Department of Public Works on 315-448-2489 rather than to the county line, so make that call first and log the time.
