Septic Tank Replacement
Professional septic tank replacement for residential and commercial properties across our service area
5 Highlights on Septic Tank Replacement
- Full excavation and removal — Our crews dig out failing, cracked, or collapsed septic tanks using backhoes and excavators, then haul away all old concrete, fiberglass, or polyethylene materials for proper disposal at certified facilities.
- Precast and reinforced tank installation — We install new septic tanks sized to your household or commercial demand, connecting inlet pipes, outlet pipes, baffles, and effluent filters to meet current health department codes.
- Distribution box and drain field integration — Every septic tank replacement includes inspection of your existing distribution box, lateral lines, and leach field to confirm the new tank connects properly to your subsurface drainage system.
- Permit coordination and soil testing — Our licensed septic contractors handle all permit applications, percolation tests, and soil evaluations required by local health departments before any ground gets broken.
- Backfill, grading, and site restoration — After we set and connect the new tank, we backfill with approved materials, compact the soil, and grade your yard to direct surface water away from the septic system.
Why Choose Our Septic Tank Replacement
Septic tank replacement is a major investment in your property’s wastewater infrastructure. A-1 Bill Gibson Septic Service has built a trusted reputation by replacing failing septic systems with precision, speed, and full regulatory compliance.
Our team holds all required state and local licenses. Every septic contractor on our crew carries certification in tank installation, soil assessment, and wastewater system design. We don’t subcontract the work. The same qualified professionals who survey your site also excavate, install, and inspect the finished system.
We stand behind every replacement with a written workmanship guarantee. That means if a connection leaks, a baffle shifts, or a riser seal fails within the warranty period, we come back and fix it at no charge.
Pricing stays transparent from the first estimate. We break down every cost — tank unit, excavation, pipe fittings, permit fees, backfill material, and hauling — so you see exactly where your money goes. No surprise charges show up on the final invoice.
Our pump trucks and vacuum trucks run daily across the service area, so scheduling a replacement fits your timeline, not ours. We coordinate directly with health department inspectors to keep your project moving without delays. From the initial soil test to the final inspection port check, A-1 Bill Gibson Septic Service delivers a professional septic tank replacement you can count on for decades.
Signs You Need Septic Tank Replacement
Septic tank replacement becomes necessary when repairs can no longer restore safe, compliant operation. Here are five detailed warning signs that your tank has reached the end of its service life.
Persistent sewage backups into the home: When raw blackwater or greywater backs up through floor drains, toilets, or tee fittings despite repeated pumping, the tank itself may be structurally compromised. A cracked or collapsed tank can’t hold volume or allow solids to settle properly, and no amount of unclogging will solve a structural failure.
Visible ground saturation near the tank: Soggy, odorous soil directly above or around the buried tank signals a breach in the tank wall. Effluent seeping through corroded concrete or fractured fiberglass contaminates the surrounding soil and can raise the local water table in your yard. This kind of leak won’t seal on its own.
Tank age exceeding 30 years:: Older concrete tanks deteriorate from hydrogen sulfide gas exposure, which corrodes the interior walls and weakens baffles. Obsolete designs often lack modern effluent filters, risers, and access lids, making them impossible to maintain to current standards.
Failed inspection results: When a licensed inspector documents a failing system — noting cracks wider than a quarter inch, a collapsed baffle, or a compromised inlet pipe — most health departments require full replacement rather than patchwork repair.
Chronic overloading and overflow: A tank that overflows repeatedly, even after pumping on schedule, is undersized for your current water usage or has lost capacity due to irreversible sludge buildup and structural deformation. Replacing the tank with a correctly sized unit eliminates the cycle of emergency pump calls and overflow events.
Our Septic Tank Replacement Process
Septic tank replacement follows a structured sequence that protects your property and satisfies all code requirements.
Step 1 — Site survey and soil testing. We visit your property to locate the existing tank, map setbacks from wells and structures, and perform a percolation test. Soil permeability results determine what tank type and drain field configuration your lot supports.
Step 2 — Permit application. Our office submits all required paperwork to the local health department, including site plans, soil test data, and system specifications. We don’t dig until the permit is approved and posted.
Step 3 — Tank pumping and decommission. A vacuum truck pumps out all remaining sewage, sludge, and effluent. We then disconnect the old inlet pipe, outlet pipe, and any connected distribution box lines. The old tank gets crushed in place or extracted whole, depending on material and site access.
Step 4 — Excavation and installation. Our excavator digs the new tank pit to the engineered depth and dimensions. We set the precast or fiberglass tank on a leveled gravel bed, connect all PVC piping, install baffles, effluent filters, risers, and access lids, then verify every joint and seal.
Step 5 — Inspection, backfill, and grading. A health department inspector reviews the open installation. Once approved, we backfill around the tank with clean fill, compact the soil in lifts, and grade the surface to promote proper drainage away from the system.

FAQs About Septic Tank Replacement
What is septic tank replacement?
Septic tank replacement is the complete removal of a failing, cracked, or obsolete underground tank and the installation of a new, code compliant unit. The process includes pumping, decommissioning, excavation, new tank placement, pipe connections, and backfill with final grading.
When should I replace my septic tank?
You should replace your septic tank when it shows structural failure — cracks, corrosion, a collapsed baffle, or repeated overflow despite regular pumping. Tanks older than 25 to 30 years often need replacement even without visible failure, because internal deterioration compromises safe wastewater treatment.
Why can’t I just repair a damaged septic tank?
Some damage goes beyond repair. A corroded concrete tank with multiple cracks, a deformed polyethylene shell, or a collapsed inlet section can’t be patched to meet health department standards. Replacing the entire tank gives you a structurally sound system with a full service life ahead of it.
How long does a septic tank replacement take?
Most residential septic tank replacements take two to three days from excavation to final inspection. Permit processing may add one to three weeks depending on your local health department’s review schedule.
Can I stay in my home during septic tank replacement?
Yes. We connect temporary waste handling when needed so your household plumbing stays functional. You’ll want to reduce water usage on the day we disconnect and reconnect the main sewer line, but full service resumes once the new tank passes inspection.
Does a new septic tank require a permit?
Every septic tank replacement requires a permit from the local health department. A-1 Bill Gibson Septic Service handles the entire permit process, including soil testing, site plans, and inspector coordination, so you don’t have to manage the paperwork yourself.
