Sewer availability

Definition

Sewer availability is a local determination, made under a locality's own ordinance and utility, that public sewer can serve a parcel. No statewide definition was found in Virginia law, so what counts as available, and what it requires of the owner, differs from one locality to the next.

The flat answer

Virginia leaves the word available to each locality

The Virginia Code and regulations read for this entry give no statewide definition of sewer availability, and no state test to look up.

What the Code does is hand the question to localities. Va. Code 15.2-2121 lets a locality with subdivision and land development regulations fix how water and sewer mains and connections must be installed as a condition of approving an original subdivision plat, and it lets those regulations include requirements to extend and connect to abutting or adjacent public water or sewer systems.

So whether sewer is available depends on which ordinance governs the land and which utility runs the line. On a listing sheet the phrase is a claim to check, and what it does and does not promise a buyer is set out in what public water and sewer available means.

Three local tests

Deemed served in Carroll, 300 feet in Pulaski, an availability form in Floyd

Carroll County: available means deemed served

Property is deemed to be served by public water or public sewer if public water or public sewer is available to the property.

Carroll County, Subdivision of Land ordinance, as posted (April 14, 2014)

The ordinance goes on to require owners of property deemed served to comply with the Carroll County Public Service Authority's connection requirements.

Pulaski County: a new lot near a main connects

If a new lot is within three hundred (300) feet of an existing water and/or sewer main, the lot shall connect to public water and/or sewer

Pulaski County, Unified Development Ordinance, July 2025

Floyd County: availability is a certification

Floyd County's ordinance has the Public Service Authority certify public water or public wastewater availability on a valid availability form. Reduced lot sizes on public service need that form. Standard Division lots with no public water or public wastewater start at 2 acres with 100 feet of road frontage.

Public service changes the lot size, too. Pulaski's district tables list .25 acre with public water and sewer, .5 acre with one of them and .75 acre on private well and septic, so check the table for the district a parcel sits in; how minimums like these play out across the footprint is taken up in how much land you need to build a house here.

Before a tract is divided

The utility, the subdivision agent and the health department each hold part of it

Because each locality writes its own test, the parcel-level answer never comes from a map or a listing. It comes from three desks.

  • The Public Service Authority or city utility: whether a main runs near the parcel, whether the utility will serve it, and on what extension terms. In Carroll County that is the Public Service Authority at 276-730-3170.
  • The county's subdivision agent: whether the ordinance deems the land served, requires a connection, or ties a smaller lot size to one.
  • The local health department: for any lot that will not connect, the onsite sewage permit, which is VDH's to issue through that office rather than the county's.

The water half of the listing phrase has its own statutory threshold, set out under public water. Where no sewer is available at all, whether land can still be developed is argued in developing land with no public sewer.

Questions

Questions about this term

Does Pulaski County's 300-foot connection rule reach lots that already exist?

The ordinance text quoted here is written for new lots: if a new lot is within three hundred feet of an existing water or sewer main, the lot shall connect to public water or sewer. That wording does not settle what applies to a lot created earlier, so an existing lot's connection question goes to Pulaski County and its Public Service Authority, 205 Broad Street, Dublin, 540-674-8720.
