Freeport runs its own sewer collection system, its own water system and its own building department. A sewer line job here involves the village at every step. See also our Freeport page and sewer line repair and hookups across Long Island.

Who owns what

Freeport keeps its own sanitary sewer system, which flows into Nassau County's system for treatment, according to Wikipedia. Nassau County's health department lists Freeport Village as the local sewer authority. The village handles the mains in the street; for a problem there, call its Water & Sewer superintendent at (516) 377-2379. The line from your house to the village sewer is the building's, and that's what we repair.

Why Freeport lines fail

The Census Bureau's latest five-year survey shows a third of Freeport homes built before 1940 and 64% before 1960, with a median year built of 1953. House sewers that old crack, sag, shift at the joints and let roots in. On the south side, there's another factor: much of the village sits low near the canals. About 42% of the village is in FEMA's high-risk flood zone, and Sandy put saltwater into nearly 3,500 Freeport homes. Since then, the village has raised low streets and added check valves to its storm drains.

Backwater valves on flood-zone streets

A storm can push the sewer system past capacity, and the lowest drain in the house is where sewage comes in. A backwater (sewer check) valve on your house sewer line closes when the sewer backs up, so it can't flow in through basement and utility-room drains. It works only on a sewered house, and it has to be installed where it can be reached for cleaning. We install them. See backwater valve installation.

Permits

Plumbing work inside Freeport needs a permit from the Village of Freeport Building Department, at 46 North Ocean Avenue, not the town. Before any digging, we tell you where the problem is and what the repair involves.

The water line in the same yard

Freeport also runs its own water system: 11 wells at three well fields, about 10,200 metered connections and 126 miles of mains, according to its 2025 Annual Water Quality Report. The village has a lead service line inventory and will send it on request. If your yard is being opened for a sewer repair, it's a good time to check what your water service line is made of. And after a coastal flood like the December 23, 2022 storm, when the National Weather Service logged 2 to 3 feet of water on roads south of Atlantic Avenue, it's worth having a slow or gurgling sewer line checked before the next one.

Questions

Sewer line repair in Freeport: FAQ

My main line keeps backing up in dry weather. What's wrong?

In a house from the 1950s or earlier, it's usually roots or a cracked or sagging section of the line. We clear it, find the cause, and repair or replace that section.

Can a backwater valve keep sewage out of my basement?

On a sewered house, yes: it closes when the sewer backs up. It needs occasional cleaning, so it has to be reachable. In Freeport the installation needs a village plumbing permit.

Who fixes the sewer under the street?

The village. Call the Water & Sewer superintendent at (516) 377-2379.
