The permit is the hard part
Putting a septic system in the ground takes a few days. Getting permission to put it there takes considerably longer, and that's what surprises people. In West Virginia the county health department issues the permit, the state certifies the installer, and nothing gets dug until both are satisfied.
Here's what that means for you: start early. If you're building, the septic approval shapes where the house, the well and the drain field can go — so it needs to happen before the site plan is final, not after. If your existing system is failing, the clock starts the day you call, not the day we dig.
We handle our end of it: the perc test, the installer sign-off on your application, and the coordination with Jefferson or Berkeley County so it keeps moving.
01
Perc Test & Site Evaluation
A percolation test measures how fast your soil takes water. That number, plus the soil profile and depth to rock or water table, determines what kind of system your property can support — and sometimes whether it can support one at all.
- Test pits dug and soil profile evaluated
- Percolation rate measured and recorded
- Depth to bedrock and water table checked
- Results feed your permit application
02
Tank Installation & Replacement
Tank set level on a proper bed, inlet and outlet tied in, risers brought up so the lids are reachable when it's time to pump. A tank set out of level costs you the whole system eventually, so this is not a step to rush.
- New concrete tank installation
- Failed or collapsed tank replacement
- Risers and access lids to grade
- Distribution box set and leveled
03
Drain Fields
The tank settles solids; the drain field does the actual treating. Laterals dug to consistent depth, bedded in stone, laid dead level so effluent spreads across the whole field instead of overloading the first ten feet of the first line.
- New drain field installation
- Failed field replacement
- Gravel and gravel-less systems
- Laterals laid level and to permit spec
04
Alternative Systems
Not every lot will take a conventional gravity field. Shallow bedrock, heavy clay, high water table or not enough usable ground and you're into a mound, an aerobic unit or another engineered design. These are common in Jefferson County — a "no" on a standard system usually isn't a "no" on any system.
- Above-ground mound systems
- Aerobic treatment units
- Peat bio-filter systems
- Pump and lift station installation
When we leave
Your yard, put back
The thing nobody asks about but everybody worries about. A septic install disturbs a lot of ground — and then we grade it, topsoil it, seed it and straw it. Come back the following summer and the only sign anything happened is two lids in the grass.
Recent work
Failed field replacement, Hedgesville
Effluent surfacing across the yard and ground too saturated to mow — a drain field that had reached the end of its life. Old field removed, new one installed to permit, and the yard graded and restored.
How a septic job runs
Six steps, start to finish
-
Site visit
We walk the property, look at slope, existing structures, the well, and where a field could physically go.
-
Perc test
Test pits dug, soil evaluated, percolation rate measured. This is what determines the system type.
-
Permit application
Your application goes to the county health department with a site plan. As your certified installer, we sign off and submit our part.
-
County review
An environmental health specialist reviews and inspects the site. This step is theirs, not ours, and it sets the schedule.
-
Installation
Tank set, lines run, field laid to the approved design, inspected before backfill.
-
Restoration
Backfill, final grade, topsoil, seed and straw. Lids left accessible for future pumping.

Common questions
Septic questions, answered
Do I need a permit to install a septic system in West Virginia?
Yes. Property owners must obtain an installation permit for all new septic systems and for major repairs or replacements of existing ones. The permit comes from your county health department, and in Berkeley County a septic permit has to be in hand before a building permit will be issued. The installer must hold a state certification and signs off on the application.
What is a perc test and how long does it take?
A percolation test measures how quickly your soil absorbs water, which determines what kind of system your property can support. The field work is usually a day. What sets the real timeline is health department scheduling and review, so start early — the results shape where the house, the well and the drain field can all go.
What's the difference between a Class I and Class II installer?
West Virginia certifies septic installers in two classes and the class determines which system types they're permitted to install. Class I covers standard soil absorption systems, absorption beds, holding tanks and effluent lift stations. Class II adds alternative and engineered designs — mound systems, aerobic units and similar. Which one your job needs comes out of the site evaluation.
How long does the whole process take?
The installation itself is typically a matter of days. The full timeline from first call to a working system is usually measured in months, because the perc test, the county review and the permit all have to happen first. This is the single most common thing homeowners underestimate.
How do I know if my septic system is failing?
Common signs: soggy ground or standing water over the drain field, sewage smell in the yard, slow drains throughout the house, gurgling pipes, or grass growing noticeably greener and faster in one strip. Any of these means get it looked at now — a field that's starting to fail is cheaper to address than one that's fully gone.
What does a septic system cost?
It depends entirely on what your soil will support. A conventional gravity system on good ground is the low end. Shallow rock, heavy clay or a high water table can push you into a mound or an aerobic unit, which costs substantially more. We can't give you a real number until the perc test tells us what the site needs.
Can you install on a lot that failed a perc test?
Often, yes. A failed conventional perc doesn't automatically mean no system — it usually means you need an engineered one. Mound systems, aerobic treatment units and peat bio-filters exist precisely for ground that won't take a standard field. Jefferson County has plenty of all of them in service.
How far does a septic system have to be from my well?
State code sets minimum setback distances between the system, the well, property lines, structures and any surface water. Those setbacks are a big part of why the site evaluation happens before the site plan is finalized — on a tight lot they can decide where the house goes.
Will installing a septic system destroy my yard?
It disturbs a lot of ground, and then we put it back. Backfill, final grade, topsoil, seed and straw. By the following summer the visible evidence is usually two tank lids sitting in the grass. Keep vehicles and heavy equipment off the drain field afterward and it stays that way.
How often should a septic tank be pumped?
Every three to five years for a typical household is the common guidance, though it depends on tank size and how many people are on it. Only human waste and toilet paper should go down — no grease, chemicals, wipes or tampons, whatever the packaging claims. Pumping is a service you'd call a tank cleaner for; we install and repair.
Start the process early
Whether you're building or your current system is failing, the sooner the perc test happens the sooner everything else can move. Call and we'll tell you what your property needs.
