Baldwinsville's floodplain and sewers
The county hazard plan states the Seneca River flows through the center of the Village of Baldwinsville and divides it. The village straddles the Towns of Lysander and Van Buren, sits at Erie Canal Lock 24, and three developments lie in mapped flood areas: Fobes Island in the 100-year floodplain, and Bronze Foundry Lofts and Villas at Seneca in the 500-year floodplain.

River water is black water
The Seneca River runs through the center of Baldwinsville, with Fobes Island in the mapped 100 year floodplain. The industry standard lists rising water from rivers among its examples of grossly contaminated water, so river water that reaches a house is cleaned that way: soaked drywall, insulation and carpet removed, hard surfaces cleaned and disinfected, drying after. It is also a flood policy question rather than a homeowners one. Photograph the water line and the entry point before anything is removed.
Outside the county sanitary district
The Village of Baldwinsville is not on the county's list of Consolidated Sanitary District members, so a sewage backup there goes to the village, usually its DPW, not the county line. Call it before booking the cleanup, and stop running water in the house. Nearly half the village rents, 48.4 percent, so a tenant's next call is the owner, in writing.
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.

Baldwinsville questions about river and sewer water
Sewage is coming up in my Baldwinsville house. Is the county the right call?
Usually not. The village is outside the county's Consolidated Sanitary District, so backups go to the village, typically its DPW. Stop running water, keep people out and photograph where it came up while you wait.
Why can sewage-soaked drywall not be dried in place?
Because it is treated as grossly contaminated. The CDC advises removing and discarding drywall and insulation contaminated with sewage or flood water, and the industry standard treats backflow from beyond a trap as the most contaminated category.
Tell us where the water came up in Baldwinsville
Floor drain, toilet, tub or through a wall from outside. It decides what the cleanup is.
