Certified Septic Repair & Restoration — Fix Problems Without Full Replacement
Not all failing septic systems require a complete rebuild. We specialize in diagnosing issues accurately and offering repair solutions that extend the life of your system — including ATU (Aeration Treatment Unit) drop-in systems, which can be a more affordable alternative to full replacement. These systems inject oxygen into wastewater, improving treatment efficiency and restoring failing systems without major excavation.
Common Repairs:
- Leach field/drain field repair
- Tank replacement
- ATU system repairs
- Aerobic system troubleshooting
- Distribution issues
- Line repairs & rerouting
- Soil saturation mitigation
Signs that often signal septic issues are: backups, saturated fields, slow drains, and foul odors. If you are experiencing any of these problems, give us a call and we’ll take a look and give you an honest assessment.
Aerobic Systems & Affordable ATU Repairs
Many Cass County homes are required to have ATU (Aerobic Treatment Unit) systems. When these systems fail, a full replacement can be costly. As a certified Aero-Stream dealer, we can often restore failed ATUs with drop-in replacements, saving thousands over a complete system replacement.
Advantages of Aero-Stream Repairs:
- More affordable than replacing an entire system
- Quickly restores ATU function
- Approved in Cass County
- Extends system lifespan
- Save homeowners thousands vs. full system replacement
This is one of the only ATU systems the county accepts — and we are certified to install them.
Leach Field Installation & Repair
If your drainfield is saturated, backing up, or failing, we diagnose the cause and recommend the most cost-effective solution. In many cases, homeowners think they need a full system replacement—when a targeted leach field repair or rebuild may restore long-term function.
Services Include:
• Leach field replacement
• Leach field expansion
• Drainfield diagnostics
• Repair of saturated or failing drainfields
• Percolation improvement grading
Lagoon Installation & Lagoon Repair
For rural properties, lagoons remain a dependable and low-maintenance wastewater solution. We install new lagoon systems and rehabilitate existing ones that are leaking, failing, or out of compliance. If you are buying a property with a lagoon, we highly recommend having it inspected prior to purchasing. We are not (yet) a certified inspector, but we’ll be happy to take a look at it for you.
Services Include:
• Lagoon construction
• Lagoon repair & reshaping
• Bank stabilization
• County compliance adjustments
Soil Morphology Testing & Site Evaluations
Before any septic system can be installed, a proper soil evaluation is mandatory. We perform soil morphology testing to determine absorption capacity, system design, and county compliance.

What Our Septic Customers Have to Say
We were very happy with the work Richard did for us on our new build. Very responsive and helpful with explaining what he was doing and all the stipulations that the county has in place. Super nice guy, too! Definitely recommend.

Richard & his crew installed a new, fully permitted septic system for me. As full service certified septic installers, they coordinated all design and permitting for the new system. They handled all site and landscaping restoration, rebuilding a French drain and small retaining wall.

I would hire them again and will definitely recommend them to anyone I hear needing this kind of work done. Down to earth folks that take pride in what they do! Thanks guys!

Frequently Asked Questions
How do I know if my septic system needs to be repaired or replaced?
A failing drainfield, slow drains, foul odors, or standing water often signal septic trouble. After a site evaluation, we’ll tell you honestly whether a targeted repair will solve the problem—or if a full replacement is the better long-term solution.
What makes ATU repairs or Aero-Stream replacements more affordable?
ATU (Aerobic Treatment Unit) failures can often be fixed with drop-in Aero-Stream components instead of replacing the entire system. This restores function and saves thousands by avoiding a full system rebuild.
Do you handle the county permitting and inspections?
Yes. We coordinate the entire process—including soil testing, system design, county paperwork, and scheduling inspections—so your installation is compliant and stress-free.
How long does a septic installation typically take?
Most residential installations take 2–4 days depending on soil type, weather, and system design. Complex or engineered systems may take slightly longer. We’ll provide a clear timeline before work begins.
Can you repair an existing leach field, or does it always need replacement?
Not always. Many drainfields can be repaired through targeted trench reconstruction, grading adjustments, or ATU upgrades. We always explore the most cost-effective repair options first.
