Your property deserves what the city takes for granted.
Since 1998 — 400+ systems installed — serving a 75-mile radius from rural homesteads to county-approved new construction.
Serving Hardin County, Lake County, and surrounding rural townships since 1998.
Four hundred problems solved. Here are three that weren't routine.
"They hit ledge at four feet and re-engineered the field the same afternoon."
Called Trench on a Saturday when sewage surfaced in my backyard. By Monday they had a new design drawn up that worked around the ledge — the county inspector signed off on Thursday. I've never seen a crew adapt that fast on a problem that complicated.


"Every rough-in I send their way comes back with zero health department flags."
I've been subcontracting septic work to Trench on rural builds for six years. They read perc results before I even finish the report, pre-fill the permit paperwork, and have a system design ready before my concrete crew needs the site. That kind of coordination is worth more than the lowest bid.

"The design met every variance requirement. Occupancy was granted without a single revision request."
This was a tight lot with high groundwater and a setback conflict on two sides. Trench submitted a pressurized drip-distribution system with a complete soil analysis and hydraulic loading calculations. The documentation was thorough enough that we approved it on first review — which, on a site like that, almost never happens.
From phone call to permit card — here's exactly what happens.
Site Evaluation
We walk the property, read the soil, and locate any constraints — setbacks, ledge, water table. You get a written assessment the same day.
System Design & Permitting
We draw the design to county spec, file the permit, and manage every back-and-forth with the health department. You never talk to a bureaucrat.
Installation
Steel tank set, field lines routed, backfilled clean. If conditions change mid-dig, we re-engineer on-site — no extra mobilization fee.
Final Inspection & Sign-Off
We schedule the inspector, walk the site with them, and hand you a closed permit card. The file goes to the county. You're done.
Schedule a Site Evaluation
We come to the property, walk every foot of it, and give you a written assessment — soil conditions, design options, permit timeline, and a firm quote. No obligation. Most evaluations take 45 minutes.
- Written assessment delivered same day
- Permit filing included in every quote
- Emergency slots available within 24 hours
- We work directly with your county health office
