New systems and replacements
Septic installation that starts with the soil, not a guess from the truck.
If you're building, replacing a failed system, or buying a lot that still needs approval, the soil scientist's report runs the show. Clay and shallow rock are common around Johnson City. Sometimes a conventional field fits. Sometimes you need an alternative design. We install what's permitted for the lot you actually own.
When to call
- New home without sewer
- Failed drain field
- Tank beyond repair
- Adding bedrooms that change design load
- Land buy contingent on septic approval
Local wrinkle
Washington County and the Tri-Cities pull construction permits through TDEC's Johnson City Environmental Field Office. Expect a site and soil evaluation before design. Ridge lots toward Buffalo Mountain and steeper Boones Creek edges fail conventional more often than flat valley parcels. That's a soil fact, not a sales pitch.
Bottomland near the Watauga and tributaries can sit wet in a wet year. Upland lots more often fight rock and slope. We will not invent a perc rate for your ZIP.
What we do
- Coordinate with the soil evaluation
- Size tank and field to bedrooms and soil
- Pull or follow the construction permit
- Install with required inspections
- Leave you with as-built clarity when the job is signed off
Conventional gravity tank plus absorption field when soils cooperate. Shallow trench or engineered options when rock is close. Mound, LPP, drip, or ATU on marginal lots, which costs more and needs more maintenance. Alternative systems need the right installer class. Ask us what we can take on, and look it up on TDEC's installer list.
Price drivers
System type, rock excavation, slope, tank material and size, field length, restoration of drive and yard. Market talk for conventional installs here often sits around $6,000-$16,500. Engineered systems climb, often discussed in a $12,000-$25,000+ band. Those are market ranges, not a bid.
After you write
We confirm sewer vs septic, town, bedrooms, and whether a soil report already exists. Then we outline permit steps and a site visit.
Quick answers
**Does a new system need a permit?** Yes. Construction permits run through the Johnson City EFO under TDEC Chapter 0400-48-01.
**Can I skip the soil scientist?** Not if you want a legal system. Modern Tennessee practice is a soil profile, not a casual backyard perc hole alone.
**Is every Johnson City lot on septic?** No. Plenty of in-town addresses are sewer. Say so in the form so we don't quote a tank you don't have.
