Sewage Cleanup Nassau County, NY

Sewers overwhelmed in heavy rain

In a heavy rain, sewers can be overwhelmed by floodwater. When storm and sanitary lines fill at once, wastewater can back up through basement floor drains, toilets and tubs. This water is Category 3 and has to be handled as contaminated.

Tidal surge and the Bay Park plant

The South Shore Water Reclamation Facility (Bay Park) treats wastewater for a large part of the county, and in 2012 a tidal surge flooded it and affected everyone on the system. It shows how closely sewage and bay flooding are tied here. Tidal flooding that reaches low ground floors and basements can bring sewage contamination with it.

Failed or frozen lines

A cracked or root-blocked sewer lateral can send wastewater into a basement or crawl space, and a hard freeze can crack exposed drain lines. Because the line runs below the floor, damage often builds before anyone sees it. Stopping use of fixtures prevents more wastewater from entering the home.

The scope depends on how far the sewage spread, how long it sat, and what it touched. Porous materials that sewage contacts are removed, not cleaned. Hard surfaces such as concrete and tile are cleaned and disinfected. We list each material and room in a written scope for your adjuster.

A contained backup in an unfinished basement can often be cleaned and dried in two to four days. A finished basement with flooring, drywall, and contents takes longer, followed by rebuilding. We do not rebuild until readings confirm the structure is dry.
