Short answer: Long Beach is a city on a barrier island; the county lists the city as its own sewer authority. Homes that were never connected still need licensed cesspool service.
Last updated: November 2026. Sewer status from the Nassau County Department of Health community list; areas and parcels from Nassau County GIS (2026-11-07).
The City of Long Beach in numbers
The city covers 2.57 square miles with about 7,991 tax parcels (median parcel 0.09 acres) on Nassau County GIS. The county health department lists its sewer authority as Long Beach City. As a city, it runs its own building department rather than a town's. None of the nearest communities appear on the county's not-publicly-sewered list, so on-site systems here are limited to properties that were never connected.

Frequently asked questions
Which parts of the City of Long Beach have no public sewer?
None of its communities are marked 'not publicly sewered' on the Nassau County Department of Health list. Individual properties can still be unconnected; ask the sewer authority.
Can a Long Beach home get the S.E.P.T.I.C. grant?
Very few can. The barrier-island city is its own sewer authority on the county list (Long Beach City), and the grant requires a property that isn't connected to sewer or inside a district, apart from documented cases the district can't connect. The amount is up to $35,000 per the program administrator (Nassau County Soil & Water Conservation District); the county page still lists $20,000; confirm at 516-364-5861.
Who issues permits for septic or sewer-lateral work in Long Beach?
The City of Long Beach building department, not a town; the contractor needs a Nassau County Home Improvement License.
