Short answer: No active county sewer district covers Bellport on the county's GIS layer, so homes here use cesspools, septic tanks or I/A systems unless a village or private plant serves them.

Computed 2026-11-07 from Suffolk County GIS (hamlet boundaries, sewer districts, groundwater management zones, FEMA flood zones, protection areas, tax parcels). Shares are of land area; a district boundary is not a hookup, and some village-run systems are missing from the county layer. Method and full table.
Sewer coverage
No active county sewer district covers Bellport on the county's GIS layer, so homes here use cesspools, septic tanks or I/A systems unless a village or private plant serves them. A sliver (3%) is inside a proposed district (“Bellport Study Area”). Counting lots instead of land: about 1,021 of the 1,021 one-family lots touching Bellport lie outside any active sewer district, and those homes rely on on-site systems. For comparison, the nearest places: Brookhaven (0% sewered, median lot 0.51 ac); North Bellport (21% sewered, median lot 0.24 ac); East Patchogue (8% sewered, median lot 0.30 ac). By active-sewer share Bellport ranks 104 of the 165 Suffolk hamlets and villages we measured.
Groundwater, lots and flood exposure
Groundwater management Zone VI: Article 6's minimum lot for a new home on an on-site system here is 40,000 sq ft, unless the density is met another way or an exemption applies. County parcel records show 1,021 one-family lots touching Bellport, with a median of 0.34 acres (about 14,700 sq ft), below that minimum and the 94th-largest median lot in our Suffolk table. 11% of the land is in FEMA's 1%-annual-chance flood zone.
For most Bellport homes the main running cost is pumping; when a cesspool fails, the replacement must include at least a septic tank, and grants can cover most of an I/A system. With 11% of the land in the flood zone, ask whether groundwater flows back into the cesspool after pumping; in Suffolk that is a failed-system condition.
