Onondaga County WEP asks residents with sewage backing up to call 315-435-3157, which it answers at any time, every day, for properties connected to the public sewer inside the Consolidated Sanitary District. For City of Syracuse properties it directs the call to the City Department of Public Works on 315-448-CITY, 315-448-2489, and outside the district to the town or village, usually its DPW. Properties not on public sewer are told to contact a licensed plumber or service expert.

Liverpool floodplain water
The county hazard plan says large areas of the Village of Liverpool lie within the Onondaga Lake floodplain, and Bloody Brook runs through it. Rising water from a lake or stream is among the industry standard's examples of grossly contaminated water. In a Liverpool cellar from around 1938, that usually means stone or block walls, old wood and stored belongings. Stone and concrete can be cleaned and disinfected; soaked wood shelving, insulation and cardboard boxes generally go. Photograph and list them first.
The backup route in the village
Liverpool is inside the county's Consolidated Sanitary District. If water came up through a floor drain rather than through the wall, its line, 315-435-3157, is answered at any time and checks the public side. A backup and lake water may look alike on the floor, but they are read under different parts of a policy, so photograph where it came in.
Rule out the public sewer first
Stop running water and call whoever runs your sewer before a private cleanup is booked. Their side costs you nothing to check.
Ask what comes out and what is cleaned
Porous materials soaked by sewage generally come out; hard surfaces and framing are cleaned and disinfected. The list should be written down before work starts.
Photograph where it came up
The drain, the toilet or the wall it came through, and the height it reached. Backup water and flood water are read under different parts of a policy.

Liverpool questions about lake water cleanup
Can an old Liverpool stone cellar be cleaned after lake water?
Usually, yes. Stone, block and concrete are hard surfaces that can be cleaned and disinfected. What generally goes is porous: wood shelving, insulation, stored cardboard and fabric. The CDC advises boots, gloves and goggles for anyone doing the work.
Is a sewage backup covered by homeowners insurance?
Only your insurer can say. The standard HO-3 form excludes water that backs up through sewers or drains unless a water backup endorsement was added. Look at your declarations page and ask before the scope is agreed.
Tell us where the water came up in Liverpool
Floor drain, toilet, tub or through a wall from outside. It decides what the cleanup is.
