Why Choose Our Septic System Replacement
Septiclear Inc has replaced hundreds of failing and deteriorated septic systems across residential and commercial properties throughout Oregon. Our professionalism is reflected in the active contractor licenses, designer certifications, and operator credentials our team holds. We don’t subcontract the critical work – our own licensed technicians handle excavation, tank installation, perforated pipe placement, and final grading.
We pull every permit. We schedule every inspection. We coordinate directly with your county health department so you don’t have to chase paperwork, manage permit issues, or wait on approvals.
Our replacement systems are engineered to match your actual site conditions. We conduct soil profile evaluations, perc tests, and setback assessments before we spec a single component. That means your new drain field, leach field, or mound system is sized correctly for your household or commercial load – not just the minimum required. Proper sizing ensures clean, consistent performance and reduces the risk of costly repairs down the road.
We use top-rated tanks, quality aggregate, and approved perforated pipe from trusted manufacturers. Every replacement includes a properly installed outlet filter, inlet and outlet baffles, and a risered access port for future service. Components are selected to prevent leaks and protect your property from water damage caused by system failure.
Septiclear Inc backs completed septic system replacements with a workmanship guarantee. If something we installed fails due to our work, we fix it. We also offer emergency response for urgent septic failures, because homeowners and business owners can’t afford to wait when a system goes down. That’s our commitment to every customer.
Signs You Need Septic System Replacement
Sewage backing up into the home: When drains gurgle, toilets back up, or raw effluent surfaces in your yard near the drain field, your system may be beyond repair. A collapsed tank, failed baffle, or fully saturated leach field can cause sewer to reverse course through your main sewer line and back into your home, creating a serious health hazard and potential structural damage.
Persistent wet spots or odors over the drain field: A soggy, foul-smelling absorption field signals that the soil can no longer accept effluent. Biomat buildup, compacted soil, or an overloaded system can permanently reduce percolation rates. These conditions are not safe to ignore – surface runoff from a failed field poses real health and environmental risks. Drain cleaning, jetting, and pumping alone won’t restore a drain field that’s biologically or hydraulically failed.
Cracked or corroded septic tank: Concrete tanks crack over time. Steel tanks corrode and collapse. A structurally compromised tank develops leaks and can’t contain sludge or scum properly, allowing solids to migrate into the drain field and clog perforated pipes. Leak detection through camera inspection and probing often reveals damage that isn’t visible from the surface.
System age exceeding 25 to 30 years: Conventional septic systems have a finite service life. Older systems often lack outlet filters, proper baffles, and adequate tank capacity for current household loads. Continuing to patch aging components becomes costly over time. An aging system that’s been pumped repeatedly but still malfunctions is a strong candidate for full repair replacement rather than ongoing service calls.
Failed perc test or soil evaluation: If your property’s soil no longer percolates at an acceptable rate, your existing drain field can’t function. High water tables, saturated, compacted, or clay-heavy soils may require an engineered alternative system – a mound system, drip system, or sand filter – rather than a conventional replacement.
Our Septic System Replacement Process
Step 1 — Site Assessment and Soil Testing We probe and evaluate your existing system, conduct a perc test, and map soil profiles, setbacks, and property lines. We also identify the location of your main sewer line and any water line infrastructure that may affect system placement. This determines what type of replacement system your site can support.
Step 2 — System Design and Permitting Our certified designer produces a site plan and system design that meets state code and local ordinance requirements, including required setbacks from sewer lines, water lines, and property boundaries. We submit the permit application to your health department and manage the approval process.
Step 3 — Excavation and Removal Our crew excavates the failed system using a backhoe or excavator. We pump and remove the old septic tank, disconnect the force main or gravity-fed inlet, and properly dispose of all waste materials.
Step 4 — New System Installation Installing to manufacturer specifications and state code, we place your new septic tank, distribution box, perforated pipe laterals, and drain field or alternative system components. We set the inlet and outlet baffles, install the outlet filter, and connect the dosing pump or float switch if required.
Step 5 — Inspection, Backfill, and Grading We schedule the required health department inspection before backfilling. Once approved, we backfill, grade, and slope the site to direct surface water away from the new absorption field. We clean up the work area and restore the site to minimize lasting disruption.

FAQs About Septic System Replacement
What is septic system replacement?
Septic system replacement is the full removal of a failed or deteriorated septic system — including the tank, distribution box, and drain field — and the installation of a new, permitted system designed to meet current code requirements and your property’s hydraulic load.
When does a septic system need to be replaced?
Replacement is typically needed when the drain field has failed due to biomat buildup, saturated soil, or compaction; when the septic tank is cracked, corroded, or collapsed; or when the system is too old and undersized to serve the property’s current demand. Repeated pumping without improvement is a clear indicator.
Why can’t the drain field just be repaired?
A drain field that’s biologically clogged or hydraulically saturated can’t be restored by pumping or jetting alone. Once the soil’s percolation capacity is gone, the absorption field needs to be replaced or relocated. In some cases, an engineered alternative system is required.
How long does septic system replacement take?
Most residential replacements take two to four days of active work, not counting permit approval time. Permitting can take one to three weeks depending on your county health department’s workload and whether a soil evaluation is required.
Can I stay in my home during replacement?
In most cases, yes. We coordinate the disconnection and reconnection of your plumbing to minimize downtime. Your service technician will walk you through any periods when water use needs to be restricted.
Does Septiclear Inc handle the permits?
Yes. We manage the full permit process, including the site plan, soil test documentation, and health department submission. You don’t need to contact the county yourself.
How much does septic system replacement cost?
Costs vary based on system type, site conditions, tank size, and local permit fees. Conventional replacements typically run less than engineered alternatives like mound systems or aerobic treatment units. Contact Septiclear Inc for a site-specific estimate.
