Foundation and Basement Excavation
A new house needs footers before it needs water and sewer lines, and the footing drain goes in alongside the foundation. See our foundation excavation services.

Trenching Services in Knoxville, TN
Water line leaking under the yard? Need power run out to the new shop or barn? We dig it to depth, bed the pipe and backfill it so the yard doesn't sink next spring.
Google ReviewsSuperior Land Management provides trenching services for homeowners, landowners and builders across Knox County and East Tennessee: water lines, electric conduit, sewer lines, French drains and downspout lines. Trenching is one part of our excavation services in Knoxville, and the same small crew handles it. Owner Chandler Humphrey runs the Caterpillar excavator himself, out of north Knox County near Halls and Gibbs. As a Knoxville land clearing and excavation company working since 2021, we call in the TN811 locate, dig to the depth your plumber, electrician or utility specifies, bed the pipe, and compact the backfill in layers. You get an itemized quote before we start. Call or text Chandler at (865) 412-7121.
Signs It's Time for Trench Digging on Your Property
Trench problems grow. A slow yard leak becomes a washout and a big water bill; a soggy foundation corner becomes a wet crawl space. Digging once, at the right depth, costs less than digging the same line twice.
- A wet spot, sunken strip or bubbling in the yard between the meter and the house
- Your water bill jumped and nothing inside the house is running
- Water stands against the foundation or pours off downspouts into the same low spot after every rain
- You built a shop, barn or detached garage and need buried power or water out to it
- Your septic or sewer line from the house needs to be replaced or rerouted
- You bought a lot and the house plans need water, power and sewer run to the build site
What Our Trenching Service Includes
A utility trench is a narrow excavation cut to a set depth and slope so a pipe or conduit can be laid, bedded and buried without settling or getting crushed later.
- 01
Locates, Layout and Depth Before the Bucket Goes In
We submit a TN811 locate request at least three working days before digging, as Tennessee requires, and mark the route in white paint or flags so locators know where to look. Private lines, like an old power feed to a shed, may not be marked, so we ask what's buried. Depth comes from your plumber, electrician, utility and inspector.
- 02
Water Line Trench and Utility Trench Digging
We cut water line trenches below frost and at the depth your plumber or water utility calls for. Electric runs to a shop or barn follow code depths for conduit or direct-burial cable. Gas line trenches follow the gas utility's or installer's specs.
- 03
French Drains, Footing Drains and Downspout Lines
For French drains we cut the trench with steady fall to a daylight outlet, line it with filter fabric, set perforated pipe in washed #57 stone, and wrap the fabric over the top so clay fines don't plug it. Downspout lines get solid pipe to daylight or a pop-up emitter. Footing drains around a new foundation are part of our foundation and basement excavation work.
- 04
Bedding, Backfill, Compaction and Cleanup
Pipe sits on a bed of sand or fine stone. After the plumber or electrician sets and inspects their work, we backfill in lifts and compact each layer with a plate compactor or jumping-jack rammer, laying warning tape above the line. Topsoil goes back on top, raked smooth.
The Trench Excavation Problems We See Most in East Tennessee
Rock where the plans show dirt
Knox County sits in the Ridge and Valley, on limestone and shale that can show up a foot down on one end of a trench and not at all on the other. A chain trencher stalls on a ledge; an excavator rips some of it, and solid ledge needs a hydraulic hammer, priced on its own line.
Red clay that holds water and settles
East Tennessee clay turns slick when wet and shrinks when dry. Backfill dumped in all at once settles into a ditch by spring, so we compact in lifts.
Sinkholes and soft spots
Tennessee's landform survey maps 1,663 sinkholes in Knox County alone (Tennessee sinkhole data). If a trench opens into a void, we stop and look before pipe goes in.
Deep trenches that need protection
Under OSHA rules, trenches 5 feet and deeper need sloping, shoring or a trench box before anyone climbs in. We plan for it in the quote.

Itemized, line-by-line quotes: digging, bedding material, backfill, rock hammering if needed, and restoration are listed separately.
We Come Back If Anything's Wrong
We return if anything's wrong. Chandler would rather spend an extra hour compacting a lift than come back to a sunken trench, and in five years no customer has called him back about a problem with the work.
Up at 3 a.m. for Broken Lines
We're available 24/7 for broken water lines. We've dug up a leaking front-yard water line at 3 o'clock in the morning.
Learn about Chandler and the crew behind Superior Land Management.
Broken Water Line? What to Do Right Now
- Close the house shutoff where the line enters (basement, crawl space or utility room). It won't stop a yard leak.
- For a yard leak, close the valve at the meter box. If there isn't one or it won't turn, call your water utility.
- Leak at the meter or on the street side? Call the utility first. Usually the line up to the meter is theirs and the line to the house is yours.
- Keep people and vehicles off washed-out ground.
- Smell gas? Leave first. Call the gas utility or 911 from a safe distance.
- Then call Chandler at (865) 412-7121. Emergency digging still needs utility locates; your plumber makes the repair.
How Our Trenching Works
Walk the Route With Chandler
Chandler walks the trench route with you, from the meter, panel or house to wherever the line needs to end up. He looks at slope, trees, rock and septic areas. You get a written, itemized quote.
Call TN811 and Line Up the Trades
We submit the TN811 ticket at least three working days ahead and white-line the route. We confirm depth and inspection timing with your trades. Superior digs and backfills; licensed trades make the connections.
Dig to Grade With the Excavator
Chandler cuts the trench with a Caterpillar excavator and a bucket sized to the line, keeping topsoil and subsoil in separate piles. Drain lines get checked for fall as we go. Rock gets flagged to you before we hammer it.
Bed the Pipe and Hold for Inspection
We lay sand or fine stone bedding under the line and leave the trench open for inspection. Your plumber or electrician sets the pipe or conduit. Burying an uninspected line means digging it back up.
Backfill, Compact and Final Walk
We backfill in lifts, compact each one, lay warning tape over the line and put topsoil back on top. Then Chandler walks the finished line with you. You get an itemized invoice that matches the quote, and photos of the open trench showing where your line runs.
How Much Do Trenching Services Cost in Knoxville?
Most trenching jobs are priced after Chandler walks the route, because length, depth and rock change the number more than anything else. Dirt work runs $1,500 per machine day. Emergency and after-hours rates. We take cash, check and Venmo. If you want the cheapest number, we may not be your crew; if you want it dug once, call us.
What Changes the Price
- Trench length and depth (a 24-inch conduit run vs. a 5-foot-plus sewer line that needs sloping or a trench box)
- Rock: limestone or shale ledges that need a hydraulic hammer
- Access: tight yards, fences, slopes, and how far the machine travels from the road
- Bedding and drain material: sand, washed #57 stone, filter fabric and pipe for French drains
- Restoration: topsoil, seed and straw, or gravel replacement over a driveway crossing
Quoted Separately
- Plumbing and electrical connections, pipe, wire and permits by your licensed trades
- Clearing a wooded route before trenching, handled as lot clearing
- New gravel or culverts where the line crosses a drive, handled as driveway excavation
- Hydraulic hammer rental for solid rock
Estimates are free.
Often Paired With Trenching
Trenching and excavation usually share a build.
Driveway Excavation
Water and power lines often follow the driveway in from the road. See our gravel driveway excavation work.
View Driveway ExcavationLot Clearing
On a wooded lot, the trench route has to be cleared and stumps pulled before a line can go in, or roots end up wrapped around the pipe. See residential lot clearing for building sites.

How much does trench digging cost?
It depends on length, depth, rock and access, so Chandler prices most jobs after walking the route. Dirt work runs $1,500 per machine day. You get itemized, line-by-line quotes, and estimates are free.
How long does trenching take?
A typical residential run, like a water line from the meter to the house or conduit to a shop, is often dug and backfilled in a day once locates are clear. The bigger wait is usually the TN811 locate, which needs three working days' notice.
How deep do utility trenches need to be?
Depth is set by what goes in the trench and who connects it. Electric runs follow the National Electrical Code, often about 18 inches over PVC conduit and 24 inches over direct-burial cable. Water lines go below frost at the depth the plumber or utility specifies. Any trench excavation 5 feet or deeper needs sloping, shoring or a trench box under OSHA rules.
Do you connect the water line or wire the conduit?
No. Superior digs, beds and backfills; a licensed plumber or electrician makes the connections and pulls their permits. We coordinate so the trench is open when they arrive and closed after inspection.
Can you come out at night for a broken water line?
Yes. We're available 24/7 for broken water lines, and we have dug out a leaking front-yard line at 3 a.m. Shut off the water at the meter box or house valve first, then call (865) 412-7121.
Do I need to be home, and what happens to my yard?
You don't need to be home while we dig, but we want you at the final walk. Tell us about gates, pets, livestock and private buried lines first. Expect a raked strip of bare topsoil that needs seed and a season to green up.
What if something settles later?
We return if anything's wrong. In five years no customer has called Chandler back about a problem with the work.
Why choose a crew where the owner runs the equipment?
Owner runs the equipment: Chandler is the one in the excavator seat, reading the grade and rock as the trench opens.
