Septic Tank Replacement in Jacksonville, NC
When a septic tank is cracked, collapsing, or too far gone to repair, replacing it is the fix that lasts. Call and describe what’s going on for a free estimate from a local septic pro.

Replacement isn’t always the answer. A good septic tech checks the tank, baffles, and drain field first, so you only replace what actually failed.
Signs a tank may need replacing
- Cracks in the tank walls or lid, or a tank that won’t hold its level
- A sinking or collapsing spot in the yard over the tank
- Groundwater or roots getting into the tank
- An old steel tank that has rusted through
- Backups that come back soon after pumping, with no problem found in the lines
Tank replacement or a whole new system?
Sometimes only the tank has failed and the drain field is fine. Other times the field has failed too, or the home has added bedrooms since the system was built, and the county requires a larger or different system. Your contractor and the county health department sort that out before work starts.
New septic installation
Building on a lot without sewer? A new septic system starts with a site and soil evaluation by the county, which issues the permits that set the system type and size. The contractor installs the tank and drain field to that permit, and the county inspects it before it’s covered.
Permits come first
In North Carolina, replacing a septic tank or drain field needs a repair permit from the county health department, and a new system needs construction approval. In Onslow County, that’s Environmental Health. Your septic contractor should know which permit the job needs.
What affects the price
- Whether just the tank or the whole system is being replaced
- Tank size, which depends on the number of bedrooms
- The system type the county permit calls for
- Soil, water table, and how much room the lot has
- Access for equipment, and restoring the yard afterward
