Chesapeake Bay Septic Pump-Out Rules in Virginia

Sourced from 9VAC25-830 (Chesapeake Bay Preservation Area Designation and Management Regulations), Code of Virginia § 62.1-44.15:67 et seq., and Virginia locality documentation — last checked August 2026.

The Rule Itself

Under 9VAC25-830, the Chesapeake Bay Preservation Area Designation and Management Regulations:

The statutory basis is the Chesapeake Bay Preservation Act, Code of Virginia § 62.1-44.15:67 et seq. Localities are required to establish programs identifying and protecting areas where improper development could substantially harm water quality.

It applies to existing homes and businesses as well as new development. There is no grandfathering.

The Alternative Most People Miss

This is the part worth knowing before you book a pump-out.

In lieu of requiring proof of pump-out every five years, a locality may allow owners to submit documentation instead — certified by an operator or onsite soil evaluator licensed under Chapter 23 (§ 54.1-2300 et seq.) of Title 54.1 of the Code of Virginia — confirming the system does not need pumping.

In other words, a qualified professional can inspect and certify rather than pump. Whether your locality permits this varies, so ask before assuming pumping is your only route.

Enforcement Changed in 2023

A specific and dated fact that most Virginia septic content doesn’t mention.

Effective July 1, 2023, requirements directly related to onsite sewage system pump-outs are managed and enforced by the Virginia Department of Health rather than the locality in the following counties:

Accomack, Essex, Gloucester, King and Queen, King William, Lancaster, Mathews, Middlesex, Northampton, Northumberland, Richmond, and Westmoreland Counties — and the incorporated towns within those counties.

If you’re in one of these, your local health department is the contact rather than public works.

How Localities Run It

Implementation varies, and the differences are practical.

York County — Public Works sends reminder letters every five years, and receipts are submitted back to the county.

Suffolk — the CBPA is divided into five zones on a rolling five-year cycle, with the first cycle completed in 2014. Suffolk implemented the program after the Chesapeake Bay Local Assistance Board determined in June 2008 that it needed to do so for consistency with the Act. Compliance is enforced through the city’s Unified Development Ordinance.

Hanover County — applies the requirement based on where the drainfield is located, not the house. Owners can submit documentation showing their system falls outside the CBPA. Systems with VDH-permitted plastic effluent filters may also be exempted, because they already require more frequent maintenance.

Ashland — a town ordinance at Section 4.1-209(b)(5) requires it, and the town tracks compliance as state law directs.

Where CBPAs Are

CBPA localities cover most of eastern Virginia — Tidewater, Hampton Roads, the Northern Neck, the Eastern Shore, and many Piedmont jurisdictions.

Most localities publish CBPA maps. If you’re near the western edge of the watershed, or your lot straddles a boundary, it’s worth confirming rather than assuming — particularly given Hanover’s approach of looking at the drainfield location specifically.

Why It Exists

The reasoning is straightforward. Pumping removes accumulated solids before they migrate into the drainfield, which keeps the drainfield functioning as designed for considerably longer and reduces the pollution reaching groundwater and, eventually, the Bay.

The requirement is unusual in that it aligns regulatory obligation with what’s already good practice. Even outside a CBPA, pumping every three to five years is the standard recommendation.

If You’re Selling

Pump-out records matter in a CBPA locality. A buyer’s agent who knows the market will ask for them, and being unable to produce five years of compliance is a negotiating point you’d rather not hand over.

A $400 pump-out before listing is cheaper than the concession it prevents.
