Septic rules in Amherst County
Amherst County sits in the Central Virginia Health District, so septic and well permits come from the local office in the town of Amherst.
The Amherst office on 2nd Street
Call (434) 946-9408 for a permit, a record of your system or a complaint about a failing one. A construction permit is required before a new system, and our permit guide explains the sequence.
If you plan an addition near one of the county’s protected public water supply watersheds, ask the planning department what review applies before you hire a designer. Authority staff help planning with those reviews.
Authority sewer, town sewer and everything else
The Amherst County Service Authority serves the southern end of the county around Madison Heights, and its number is (434) 845-1605. Its history and a sewer extension along Route 163 are covered on the Madison Heights page.
The Town of Amherst runs its own sewer plant and serves some areas just outside its limits; the Amherst page has the contacts. Everything else in the county is on a tank and a well.
Eighteen inches of soil under the trench
Red clay is common in the Piedmont and drains slowly. Under Virginia’s sewage rules a trench needs at least 18 inches of soil below it with no rock or water table, which is why a soil evaluator checks the lot before any permit.
What we do in Amherst County
Routine work is pumping and checking the baffles. When the previous owner left no map, we run a tank and drain field location, and a riser brings the lid to grade so the next visit needs no digging.
For a failed field, drain field installation follows the health department’s permit. Water backing into the house goes to emergency septic service.
Amherst, Madison Heights and the county line
The town of Amherst and Madison Heights have pages of their own. Lynchburg sits across the James River from Madison Heights, and Nelson County lies to the north, in a different health district.
Buying or selling a house in Amherst County
No state rule makes a seller order a septic inspection. Since July 1, 2025, though, any inspection a lender, agent or buyer asks for must follow the minimum standards in Va. Code § 59.1-310.9 and be done by a licensed inspector. A real estate septic inspection from us covers the tank, the baffles, the distribution box and the field.
Ask the seller for the permit paperwork, and ask the Amherst health office what it has on file. Houses in the Madison Heights area should also get a written answer on whether a Service Authority main is available, since that changes what a buyer would want to do with an old tank.
When an Amherst County field turns soft
Slow drains, gurgling, odors and lush green stripes over the field are the usual first signs, and our septic warning signs guide lists them. Sewage on the ground is something the county’s environmental health staff investigate, so a report to the health department is reasonable as well as a call to us.
Calling Dunn Rite about an Amherst County address
Call (434) 221-9885. Tell us your road, whether you are inside the Service Authority or town lines, and what you can see in the yard. Pumping and repairs work within about 40 miles of Lynchburg and installs go up to 120.

Common questions
Is Madison Heights on public sewer?
Much of it is, through the Amherst County Service Authority, which began as the Madison Heights Sanitary District. Coverage is not uniform, and the authority has been planning extensions. Call (434) 845-1605 with your address to learn whether a main runs past it, and get the answer in writing if you are buying.
Does the Town of Amherst have its own sewer?
Yes. The town operates its own wastewater treatment plant and serves some areas just outside its limits. Sewer service starts with a water account at Town Hall. Homes beyond the town’s collection lines usually have a septic system, and the health department in Amherst permits those.
Do I need approval to build near a county reservoir watershed?
Amherst County has protected public water supply watershed districts, and Service Authority staff help the planning department review development in them. Ask the planning department what applies to your parcel before you design an addition or a new drain field, since a review can add steps before the health department permit.
Which health district is Amherst County in?
The Central Virginia Health District, the same one as Lynchburg, Bedford and Campbell. The Amherst office handles septic and well permits at (434) 946-9408. Nelson County, just north, is in the Blue Ridge Health District instead, so permits there come from a different office.
How deep does the soil have to be under a drain field trench?
Virginia’s sewage handling rules call for at least 18 inches of soil below a trench with no rock or seasonal water table. A licensed soil evaluator checks this with test holes before the health department issues a permit. Lots that fall short may need a different design or may not qualify for a conventional system.
