Septic Tank Installation in San Bernardino, CA
Full-Service Septic Tank Installation
If you're building a new home, adding bedrooms, or replacing a septic system that just failed inspection, San Bernardino County won't let a single trench get backfilled until your design, percolation results, and plot plans clear review. Payless 4 Plumbing designs and installs new septic tank systems across San Bernardino and the Inland Empire, and we carry the project from that first site evaluation through the county's final sign-off.
Pipe slope must be right. So does tank leveling, the distribution box, and the leach line layout. One piece off, and the whole system can fail inspection.
Call (909) 327-2157 or schedule a septic tank installation evaluation online to find out what your San Bernardino property needs before construction starts.

Why Your Soil Determines Whether the System Will Work at All
A percolation test measures how quickly water drains through the ground, and it's what tells us, and the county, whether your soil can safely filter and absorb wastewater at all.
Running one isn't complicated, but it takes patience. We dig test holes at the depth the design calls for, fill them with water, and let them soak overnight so the soil reaches a stable saturation point.
The next day, we refill the holes and time how many minutes it takes the water level to drop. That number becomes your site's percolation rate, and it goes straight into the design we submit for review.
Septic Permitting Requirements
Before a shovel goes in the ground, the county or city must approve the design based on your percolation results.
Permitting requires:
- A percolation report – Documenting the test results and the design rate for your soil.
- Plot plans – Showing your property line, house footprint, and the septic system's exact dimensions and location.
- County or city permit approval – San Bernardino County Environmental Health Services, or your city's building department, reviews the plans before construction starts.
- A C-42 sanitation license – Installing a septic tank and its absorption system falls under this specific state contractor license. Our crew holds it.
Skip any part of that review, and the system that gets built is the one that fails its final inspection.
How Long Installation Takes, Start to Finish
Once permits clear, the physical installation typically takes three to five days from excavation to backfill. That's the easy part to plan around.
The harder part is everything wrapped around it. Site evaluation, percolation testing, plan review, and the final inspection all add time before and after the crew is ever on-site, which is why the full project usually runs one to four weeks depending on how fast the county review and soil results come back.

Frequently Asked Questions About Septic Tank Installation
These are the questions we hear most from homeowners planning a new septic system or replacing one that failed. If your project doesn't match what's covered here, our team can walk through the specifics with you.
How Do I Know What Size Septic Tank I Need?
Tank size is set by your home's bedroom count, starting at 750 gallons for one to two bedrooms and going up to 1,500 gallons for five to six bedrooms. If you're adding bedrooms as part of a remodel, the tank and leach field usually need to be sized up to match.
What Happens If My Property Fails the Percolation Test?
A slow percolation rate usually means the leach field has to be larger, or the design shifts toward a different absorption system. It doesn't mean the property can't support a septic system, just that the design has to account for how the soil drains.
How Long Does the Permit Process Take?
That depends on how quickly plan review clears and how fast percolation results come back. The full project can run one to four weeks even though installation itself only takes a few days.
Can I Use a Seepage Pit Instead of Leach Lines?
In some cases, yes, particularly where a clay layer makes a seepage pit's vertical design a better fit than horizontal trenches. Seepage pits aren't allowed in mountain areas, so the right choice depends on your lot.
Do I Need a Permit If I'm Just Replacing an Old Tank?
Yes. Replacing a septic tank goes through the same design review, percolation, and permitting process as a new installation. The county treats it as a new system going into the ground.
