Water Damage Drying in Bayonne When Both Bays Run High
On a peninsula with 29 outfalls the question is never whether there was a storm. It is what the drain did while it rained.

Why Bayonne water comes back up the lateral
Bayonne has 29 active combined sewer outfalls, the most of any municipality in this area, 28 of them on the Bayonne City Municipal Utilities Authority permit, and the city is a peninsula with Newark Bay on one side and New York Bay on the other. Almost every neighborhood is near a relief point, which sounds reassuring until both bays run high at once and the system has nowhere to discharge. Then the pressure goes back up the laterals, and what arrives in the basement is combined sewage rather than rainwater, which means the soaked porous material leaves the building instead of being dried in place.
What water damage drying involves in Bayonne
What to do first in a Bayonne basement, and in what order
Do not start extracting while the line is still surcharged, because that water comes straight back and you pay for the same hour twice. Get contents up, cut power to wet circuits, and watch the drain rather than the sky: on September 1, 2021 Newark recorded 3.24 inches of rain between 8 and 9 in the evening, its wettest hour on record, and that event is the one that put 58 paid claims on this city's file. Once the drain stops running backwards the category decides the scope. Clean water dried inside 24 to 48 hours in most cases grows nothing at all. Water from beyond a trap takes the drywall, the insulation and the pad out with it, and the extra cleaning and decontamination the state describes for sewage belongs on the invoice as its own line.
Whether both bays are high
With 29 outfalls and nowhere to discharge, the relief path reverses and the lowest indoor opening takes it.
Whether to pump now or wait
Extraction against a surcharged line is repeat work. Contents up and power off first.
Whether sewage cleaning is itemized
Water that contained sewage calls for additional assessment, cleaning and decontamination. It should appear as its own line, not be assumed.

On September 1, 2021 Newark recorded 8.41 inches of rain, its all time wettest day, including 3.24 inches between 8 and 9 pm, the site's all time wettest hour on record. Its two hour total of 5.06 inches and six hour total of 7.88 inches were also records, and both Newark and Central Park saw amounts exceeding the 500 year storm.

The EPA states that water damaged areas and items should be dried within 24 to 48 hours to prevent mold growth, and that if wet or damp materials are dried within 24 to 48 hours of a leak or spill, in most cases mold will not grow.

What Bayonne callers ask with water coming up the drain
Why does my drain back up when it is not even a storm?
Because the relief system here depends on somewhere to put the water. Bayonne is a peninsula with 29 combined sewer outfalls between Newark Bay and New York Bay, and when both bays are high at once there is nowhere to discharge, so pressure travels back up the laterals. A heavy hour of ordinary rain at the wrong state of tide is enough.
Is the extra cleaning after a backup a real cost or an upsell?
It is a real and separately describable step. The Department of Health states that where the water that caused the problem contained sewage or other hazardous substances, additional steps are required to assess, clean and decontaminate the area. So it belongs on the invoice as its own line, and you should be able to see what it covers: which surfaces, what method, and what was disposed of rather than cleaned.
