Septic Tank Replacement
Professional septic tank replacement for residential and commercial properties across your service area
5 Highlights on Septic Tank Replacement
- Full system removal and installation — Our crew excavates the failed or corroded septic tank, disconnects inlet and outlet pipes, decommissions the old unit, and installs a new precast concrete, fiberglass, or polyethylene tank sized to your household or commercial demand.
- Licensed and certified technicians — Every septic tank replacement we perform is handled by qualified installers who hold current certifications and carry full liability coverage, so your new system meets all local health department codes.
- Permit coordination included — We pull all required permits, schedule the perc test and site evaluation, and submit as-built drawings to your county health department on your behalf.
- Drain field assessment at no extra charge — During every septic tank replacement, our team inspects the distribution box, lateral lines, and absorption trenches to confirm your existing drain field can handle effluent from the new tank.
- Backfill and grade restoration — After we set the new tank and connect all piping, we backfill with approved aggregate and bedding material, compact the soil, and grade the surface so your yard drains properly and looks clean.
Why Choose Our Septic Tank Replacement
Septic tank replacement is a major investment in your property’s wastewater infrastructure. Action Septic Service has completed hundreds of residential and commercial tank replacements, and we bring that field experience to every job site.
We don’t subcontract. Our own excavator operators, pipe fitters, and certified installers handle the work from the first shovel to the final inspection. That means one point of contact, one schedule, and one team accountable for the finished system.
Our pricing is straightforward. You’ll receive a written estimate that covers excavation, the new tank, all fittings and risers, backfill material, compaction, grading, permit fees, and the final health department inspection. No surprise line items show up after the backhoe arrives.
We stock tanks from trusted manufacturers in concrete, fiberglass, and polyethylene so we can match the right material to your soil conditions, water table depth, and local code requirements. Every tank we install includes watertight risers and secure lids for easy future access.
Action Septic Service also guarantees our workmanship. If any connection, seal, or fitting we installed fails within the warranty period, we’ll return and repair it at no cost. Your new septic tank replacement is backed by a company that stands behind its work.
Signs You Need Septic Tank Replacement
Septic tank replacement becomes necessary when repairs can no longer restore a functional, compliant system. Here are five warning signs that your tank has reached the end of its service life.
Persistent sewage odors near the tank or inside your home: A cracked or corroded tank allows odorous gases to seep through the soil and into your living space. If pumping and minor repairs haven’t resolved the smell, the tank walls or dividing wall have likely failed beyond repair.
Standing water or saturated soil over the tank area: When a concrete tank deteriorates, wastewater leaks through fractures in the walls and floor. You’ll notice soggy ground, unusually green grass, or pooling effluent directly above the buried tank. This contaminated groundwater poses a hazard to wells and nearby surface water.
Repeated backups after recent pumping: A functional tank should operate for years between pump-outs. If your drains back up within weeks of desludging, the baffles may have collapsed, the inlet or outlet pipe connections may have separated, or the tank itself may have shifted in the soil. These structural failures call for full septic tank replacement rather than patchwork fixes.
Health department notice of non-compliance: Inspectors can flag a system as failed when they detect elevated coliform, nitrates, or phosphorus in nearby groundwater monitoring. A non-compliant tank that cannot pass reinspection typically requires complete replacement to meet current code.
Tank age exceeding 30 years: Older concrete and steel tanks corrode from hydrogen sulfide gas produced during anaerobic decomposition. Even if the system still functions, a tank past its expected lifespan carries a high risk of sudden structural failure. Proactive septic tank replacement prevents emergency situations and costly property damage.
Our Septic Tank Replacement Process
Septic tank replacement is a multi-step project that we complete in a structured sequence to protect your property and meet all regulatory requirements.
Step 1 — Site evaluation and diagnosis. We locate the existing tank, assess soil conditions, measure setbacks from wells and property lines, and determine the water table depth. If your county requires a new perc test, we schedule and conduct it during this phase.
Step 2 — Permitting. We prepare the permit application, attach the site plan and proposed system specifications, and submit everything to the local health department. Work begins only after we receive written approval.
Step 3 — Pump and decommission the old tank. Our vacuum truck pumps all sludge, scum, and remaining effluent from the existing tank. We then disconnect the inlet and outlet pipes and either crush the old tank in place or extract it, depending on material and site access.
Step 4 — Excavation and tank installation. Our backhoe operator excavates the pit to the engineered depth, sets a compacted bedding layer, and lowers the new tank into position. We level the tank, connect all inlet and outlet piping, install risers and access ports, and verify watertight seals at every joint.
Step 5 — Backfill, compaction, and final inspection. We backfill around the tank with approved material, compact in lifts to prevent settling, and grade the surface. The health department inspector then reviews the installation, and we submit the as-built drawing to close the permit.

FAQs About Septic Tank Replacement
What is septic tank replacement?
Septic tank replacement is the complete removal or decommissioning of a failed, corroded, or non-compliant septic tank and the installation of a new tank in its place. The process includes excavation, pipe disconnection, old tank disposal, new tank placement, connection of inlet and outlet piping, backfill, compaction, and a final health department inspection.
When should I replace my septic tank?
You should replace your septic tank when it shows structural failure such as cracked walls, collapsed baffles, or corroded fittings that can’t be repaired. Tanks older than 25 to 30 years, tanks flagged as non-compliant by an inspector, or tanks causing repeated backups and groundwater contamination are all strong candidates for replacement.
How long does a septic tank replacement take?
Most residential septic tank replacements take two to five days from excavation to final inspection. Permitting can add one to four weeks depending on your county’s review timeline. Larger commercial systems or sites with high water tables or difficult access may require additional time.
Can I replace my septic tank in the same location?
Yes, in most cases we install the new tank in the same excavation as the old one. If soil conditions have changed or current setback requirements have been updated, we may need to relocate the tank to a compliant position on your property.
Does a new septic tank require a new drain field?
Not always. During every septic tank replacement, we inspect the distribution box, lateral lines, and absorption trenches. If the existing drain field is functional and the soil isn’t saturated or clogged with biomat, we connect the new tank to your current leach field. A failed drain field requires separate replacement.
How much does septic tank replacement cost?
Costs vary based on tank size, material, soil conditions, permit fees, and site accessibility. A standard residential septic tank replacement typically ranges from $3,000 to $10,000 or more. We provide a detailed written estimate before any work begins so you know the full cost upfront.
