Trenches for Drains and Utility Lines

Mid South Mulch offers trenching services in Franklin, TN, with trenches cut by our own excavators. We dig for French drains, downspout lines, water service lines and electrical conduit. On new-home and builder sites, we cut the utility runs too. Trenching is part of our excavation work, and the digging, loading, hauling and grading all happen in-house.

We started out mowing and landscaping in 1996, then moved into trucking, excavation, grade work and site work. Our machines include excavators, a compact track loader, compaction equipment and dump trucks. We give free on-site quotes, and the trench route gets planned with you at the site.

What kinds of trenches do we dig?

We dig trenches for drain pipe, water service lines, electrical conduit and utility runs on building sites. Drain trenches carry French drain pipe and the buried lines that move water away from downspouts and low spots. That pipe is our work, and its depth comes from the downhill slope it needs to reach an outlet. The full drain process is on our French drain and yard drainage page.

Water service lines and electrical conduit run to houses, shops, barns and detached garages. On those lines, the trench is ours, and the trade or utility that owns the line sets it. On new-home and builder sites, we cut utility runs as part of site preparation for a new build. The trades and utilities set their lines, and then we backfill the trench.

How deep does a trench need to be?

The depth depends on the line, and for utility lines the code, the utility or the inspector sets it. Where Middle Tennessee Electric supplies power, its Underground Installation Guide covers service trenches for single-family homes in developed subdivisions. Each one runs between the meter spot and the power source the utility picks, at the depth its drawings show. Its inspector checks the trench and conduit before backfill and before any wire goes in.

Drain trenches follow a different rule, since the pipe has to slope downhill the whole way to its outlet. A Williamson County soils document says several soil series mapped in the county are known for being shallow to rock. The same document lists seasonal water tables and abrupt clay layers among the most common restrictive soil conditions in county soil mapping. Rock and wet clay both change how a trench gets dug and backfilled.

What rules apply when a trench is dug?

Two sets of rules apply: Tennessee's 811 law before the dig and OSHA's trench rules while it is open. The 811 law covers any work that moves or disturbs the earth, and a trench does both. Whoever does the digging must get a TN811 locate ticket. That notice has to go in at least three and no more than ten working days before digging starts.

OSHA's trench rules get stricter as a trench gets deeper. A trench 4 feet deep or more needs a stairway, ladder, ramp or other safe way out. At 5 feet or deeper, OSHA requires a cave-in protective system unless the trench is cut entirely in stable rock. Dug-out dirt and equipment must stay at least 2 feet back from the edge or be held by retaining devices.

What happens to the trench after the line goes in?

Once the line is in, we backfill the trench in layers and pack each one down. Those layers are called lifts, and our compaction equipment packs each lift before the next goes in. Packing in lifts makes the ground over the trench less likely to settle later. Middle Tennessee Electric's guide calls for rock-free dirt or sand to backfill a new home's service trench.

Extra dirt can be spread on site or loaded into our dump trucks. Hauling off the extra dirt also takes away any rock the excavator turns up. Then we smooth the top and put the surface back over the trench line. We can seed or sod over it too.

How much does trenching cost?
HomeGuide's 2026 excavation guide puts trenching at $5 to $12 per linear foot. That is a national range, and depth, length, rock and access all change the price of a real trench. Our Middle Tennessee excavation cost guide lists more trenching prices. For your trench, call (615) 599-7550 for a free on-site quote.
Do you install the water line or the electric wire?
No. On water, electric, gas and sewer lines, the trench is ours. The trade or utility that owns the line sets it. Drain pipe is different: we lay French drain pipe and buried downspout lines ourselves. Once a utility line is in and checked, we backfill the trench in packed layers and put the surface back.
Does Tennessee's 811 law apply to a small trench?
Yes. Tennessee's 811 law covers any activity that moves or disturbs the earth, and a short drain trench does that. Whoever does the digging must get a TN811 locate ticket before the work. The notice has to go in at least three and no more than ten working days before digging starts.
What happens if the trench hits rock?
A Williamson County soils document says several soil series mapped in the county are known for being shallow to rock. If an excavator meets solid rock short of the needed depth, we stop and go over the options with you. Rock that comes out of the trench goes in our dump trucks instead of back around the pipe.
Do you dig trenches to a shop or barn?
Yes. We dig trenches for water lines and electrical conduit running to houses, shops, barns and detached garages. The trench is ours, and the trade or utility that owns the line sets it. The code, the utility or the inspector sets the depth, and we dig to that depth. Then we backfill in packed layers and put the yard back.
Can you dig the trench to move my power line underground?
Yes. We dig the trench, and the utility and your electrician handle the line itself. If Middle Tennessee Electric is your utility, it lists that trench among costs separate from its own service. The trench runs from the easement to the building, at the depth the utility's drawings or the inspector set. We backfill once the line is in and checked.
Do you dig utility trenches on builder sites?
Yes. We do light site prep for new homes and commercial construction sites, and utility trenches are part of it. We cut the runs where the plans show them, then backfill once the trades set their lines. We work in Franklin, Brentwood, Spring Hill and other nearby towns in our service area.
