Shared wellsone well, more than one owner, and the paper that has to hold it together

The Code of Virginia defines a private well in one line, and there is one person in that line.

Va. Code 32.1-176.3 defines a private well as "any water well constructed for a person on land which is owned or leased by that person", and the private well regulations repeat the same idea. Picture one drilled well on one parcel, with a supply line running across the boundary to a second house. The owner of the first parcel fits the definition exactly. The owner of the second house draws the same water from ground they do not own, and the definition does not say what that makes their share of the well.

The rest of the well rules keep the same one-owner shape. The inspection statement the health department issues for a new well is not a warranty of water quality or quantity, or of how long the well will work, and the regulation puts maintenance, repair, replacement and abandonment on "the owner or subsequent owner". With two households on one well, no Virginia well rule cited on this page says which owner that is or how two of them divide it.

How a single private well is permitted, sited, built and inspected is its own subject, covered in wells, explained. This guide stays with the part that changes when a well has more than one owner.

Two or three connections sit far below the line. The line itself is written in the Code, and it does not count houses.

"Waterworks" means a system that serves piped water for human consumption to at least 15 service connections or 25 or more individuals for at least 60 days out of the year.

Va. Code 32.1-167

Either measure is enough: the service connections or the people served. The private well regulations expressly exclude wells constructed as a groundwater source for a waterworks, so the private well rules are not the ones that govern a well serving a waterworks. A shared arrangement growing toward either number is one to take to VDH's drinking water program before another house is connected. What public water means, and where a waterworks fits, is defined in the glossary entry on public water.

Sewage is handled differently, and the contrast is useful. When a single septic system serves multiple dwellings or multiple lots, the onsite sewage regulation lets the construction permit issue only to a single owner, who has to provide legal documentation assuring operation and maintenance for the expected life of the dwellings, as set out under developing land with no public sewer. The private well regulations cited on this page contain no parallel rule for a shared well, which is why those terms end up in the owners' own paper.

A sale is when an old understanding about a shared well turns into a line in somebody's due diligence.

VDH says it does not require anything when property with a private well is bought or sold: the well regulations require neither a well inspection nor water quality testing for a transfer, though a locality or a lender may. Whether a sale needs a test at all is taken up in whether you need a well test to sell your house.

A buyer of the parcel the well sits on becomes the regulation's subsequent owner, and an inspection statement issued years ago is still no warranty of the water or of how long the well will run. For a shared well, what binds the buyer of either parcel depends on what was recorded and what it says, and the buyer's attorney is the one to read it.

For a seller, the paper worth gathering before a listing is the recorded easement, any written agreement, and whatever well records the local health department holds (VDH notes that private well records were not required before 1990). More land and water questions are collected in the land and real estate answers.
