Who handles septic permits
Burke County Environmental Health permits and inspects on-site wastewater systems across the county. Its Septic page lists the applications: a septic permit application, an existing septic verification application, an authorization for an agent to act for the owner, a form for realtors and an engineered option form. The fees are set in Attachment A of the county's approved FY 2026-27 budget.
For new construction or a perc test on land you are thinking of buying, the county's Planning and Zoning page says a zoning permit is required before Environmental Health can evaluate the site.

Improvement permits and construction authorizations
A new system needs two approvals. The improvement permit says the site can support a system, based on a soil and site evaluation. The construction authorization approves the specific system to be installed. Burke County charges them separately or as a combination, with different figures for homes up to four bedrooms, larger homes and commercial systems.
A site evaluation looks at topography and landscape position, soil characteristics, soil wetness, soil depth, restrictive horizons and available space. Foothills lots with shallow soil or steep slopes can need a pump system or an advanced design.
Know what the city and county charge, then let an independent local plumber price the repair.

Signs of trouble include slow drains throughout the house, gurgling in plumbing, sewage odors in the yard, wet or unusually green ground over the drain field, and backups into the lowest fixtures. Pumping the tank can relieve the symptoms for a while, but if the drain field has failed, the system needs a repair permit.
Burke County lists a flat fee for a repair permit and no charge for replacing a septic tank. Environmental Health performs a site evaluation and writes a permit for a partial or full repair, with instructions for abandoning the old system where needed. Do not dig up or replace drain lines before the permit is issued.
Connecting to an existing system
Adding a bedroom, placing a manufactured home on a lot with an old tank, or reconnecting a house that has been empty usually needs a verification of the existing system. Environmental Health checks that a system exists, is not failing and is sized for the use. If the house is not attached within the permit's time limit, the verification can expire, so schedule the connection promptly.
Expanding an existing system to serve more bedrooms is a separate permit with its own fee.
Re-inspections for pump and advanced systems
Some systems need regular re-inspection by the county. The fee depends on the system type, and the county waives it if the owner has a certified operator under contract. If you are buying a house with a pump or advanced system, ask the seller for the operator contract and recent inspection records.
| System type | Fee | Source |
|---|---|---|
| Type IIIb, every 5 years | $100.00 | Burke County FY 2026-27 fee schedule |
| Type IV, every 3 years | $125.00 | Burke County FY 2026-27 fee schedule |
| Type V, once per year | $175.00 | Burke County FY 2026-27 fee schedule |
| Type VI, every 6 months | $175.00 | Burke County FY 2026-27 fee schedule |
What a plumber does and what the county does
A plumber handles the building drain inside and under the house and the line out to the tank. A septic contractor installs or repairs tanks and drain fields under the county's permit. Some companies do both. Make sure whoever does the work knows which permit covers it; work on the drain field without a permit can lead to an order to redo it.
If the house is inside Morganton city limits, it is probably on city sewer; see the sewer backup guide instead.
Buying land or a house on septic
If you are buying a lot to build on, the septic evaluation decides what you can build. Get a zoning permit, then apply to Environmental Health for an improvement permit before you close if the contract allows it, so you know the site can support a system for the number of bedrooms you plan. A lot that needs a pump or advanced system will cost more to develop and may carry re-inspection fees for as long as you own it.
If you are buying a house on septic, ask the seller for the permit records, the last pumping date and any repair history. The county's Septic page includes a request form for realtors. A septic inspection by a qualified contractor before closing can reveal a failing drain field that would otherwise become your problem the first wet winter.
Living with a septic system
Pump the tank on a schedule suited to its size and the household. Keep vehicles and heavy equipment off the drain field, and do not plant trees over it. Spread laundry loads through the week rather than doing them all on one day. Keep grease, wipes and chemicals out of the drains. These habits extend the life of a drain field far more than any additive.
Septic records for your property
Burke County Environmental Health keeps permit records for existing systems, which can show the system type, the tank size and the drain field layout. Those records help a plumber or septic contractor find the tank without digging test holes all over the yard. Ask the office how to request records for your parcel, and keep a copy with your house papers once you have it.
