Excavation Services in Columbus, Ohio

Excavation is the open-cut method for installing, replacing, and repairing sewer and water lines when trenchless lining or pipe bursting is not the right call. Wooley Water Sewer Trenchless has been digging across the Columbus, Ohio metro since 1978 — running our own owned fleet of excavators, mini-ex, and dump trucks, pulling permits with Columbus Public Health, Franklin County, and the surrounding municipalities, and restoring every surface we open. We do the digging when digging is the right answer, and we say so when it isn't.

Method Definition

What Excavation Work Actually Is

Excavation — also called open-cut work or trenching — is the traditional approach to underground sewer and water service: dig a trench from the structure to the city main, lay or replace the pipe in a properly graded bed, pressure-test or camera-verify the new run, then backfill and restore the surface. It is the oldest method in the trade and it is still the right answer for an entire class of jobs that trenchless cannot handle.

At Wooley, excavation is roughly one-third of what we do. The other two-thirds — CIPP pipe lining and pipe bursting — are the reasons most people find us. But when a pipe is fully collapsed, severed by a contractor's auger, missing entirely (new construction, ADUs, additions), or hidden behind a service that is itself failing, the trenchless tools cannot work and the trench is the right tool.

We dig because we want the right method on every job, not because every job looks like a nail. The crew, the equipment, the permit relationships, and the surface-restoration discipline are the same crew that's been doing trenchless work for the last two decades — applied to a different toolset.

Method Selection

When Excavation Is the Right Method

Excavation is the correct method when trenchless cannot work, when there is no host pipe to line or burst, or when the surface conditions favour an open cut over an entry-and-exit pit pair.

No existing pipe to line or burst — new construction, ADUs, additions, or properties that never had a lateral or water service.

Fully collapsed pipe — when the host pipe has lost its cross-section, CIPP cannot support the cure pressure and bursting may not have a clear pull path.

Severed water main from a contractor's auger, fence-post auger, or directional drill — the line is in two pieces and needs to be reconnected.

Isolated spot failure — a single 6-foot section of pipe is bad and the rest is fine; a targeted dig is cheaper than relining the entire run.

Material transitions that trenchless tools can't bridge — clay to cast-iron, lateral-to-stack, or non-standard fittings that need a hand-built repair.

Water service installation — water lines are usually shallow enough and short enough that open-cut is faster and cheaper than mobilising trenchless equipment.

Surface conditions favour the cut — an open yard with no mature landscape, an existing torn-up driveway already scheduled for replacement, or a site where the surface will be redone anyway as part of a larger renovation. The trench becomes the cheaper path when restoration is already in the scope.

The honest test: if Wooley can solve your problem with trenchless work and save the yard, we'll quote it that way. Our trenchless sewer repair hub walks through method selection. If trenchless isn't right, this hub explains the open-cut path.

How We Dig

Our 9-Step Excavation Process

Every Wooley excavation — install or repair, sewer or water — runs through the same nine-step sequence. The order is fixed; the schedule is whatever the jurisdiction's inspector allows.

1

Permit pull

We pull the permit in the property owner's name with the right jurisdiction — Columbus Public Health for Columbus and Bexley, Franklin County Public Health for unincorporated Franklin, and the corresponding county health department elsewhere. Right-of-way permits where the trench crosses public property are filed separately with the municipal engineer.

Process step 1 — permit application paperwork on a clipboard
2

Utility locate (OUPS 811)

Ohio Utilities Protection Service (OUPS) 811 ticket filed at least 48 hours before the dig. Gas, electric, telecom, and water mains are flagged on the surface. We do not break ground until every utility on the ticket has cleared.

3

Surface protection & staging

Plywood pathways protect lawn from track damage. Spoil pile location is staged on tarps. We document the pre-existing condition of every surface that will be opened or driven over — concrete, pavers, fence lines, hardscaping — before the first bucket moves.

4

Trench excavation

Mini-ex for tight residential lots, full-size excavator for longer runs and commercial work. Trench width is sized to the pipe diameter plus working clearance per OSHA shoring requirements. Depth follows the existing pipe (for repair) or local code minimums (for new install). Spoil is set well clear of the trench edge.

Process step 4 — open trench with proper benching and spoil set back from the edge
5

Pipe bedding

Compacted sand or pea gravel bedding, 4 to 6 inches under the pipe, properly graded at 1/4 inch per linear foot for gravity sewer or below frost line for water. Grade is the make-or-break detail — a poorly bedded pipe will belly and back up regardless of the pipe's condition.

6

Lay or repair pipe

Sewer: PVC SDR-26 or SDR-35 with rubber-gasket joints, glued where the jurisdiction requires it. Water: Type-K copper, HDPE with electrofusion fittings, or PEX depending on the city. Fittings matched to the existing material at every transition.

Process step 6 — new PVC sewer pipe laid in a graded sand bed
7

Pressure or camera test

Water lines pressure-tested at 100+ PSI and held for the duration the jurisdiction requires (typically 15 minutes to one hour). Sewer lines camera-scoped end-to-end and, where required, low-pressure air-tested. Test results documented for the inspector.

8

Municipal inspection

Health department or building department inspector visits the open trench before we backfill. Some jurisdictions allow video walkthrough; most still require an on-site inspection. We do not backfill until the inspector signs off. If the inspector flags something, we fix it on the spot.

Process step 8 — municipal inspector reviewing an open trench
9

Backfill & surface restoration

Backfill in lifts — 12-inch compacted layers — to prevent settlement. Topsoil, seed, and straw mulch on lawn restorations. Concrete or asphalt patch for driveways and sidewalks (subcontracted to a paving partner where the scope warrants). Final walkthrough with the property owner before we leave site.

Permits & Code

Permits, Code, and Inspection Sequence

Every excavation job in Central Ohio is governed by the Ohio Plumbing Code, the local health department, and — where the trench crosses public property — the municipal right-of-way office.

Ohio Plumbing CodeOAC 4101:3 governs material, slope, depth, and inspection requirements for sewer and water service. Wooley installs to code on every job, no exceptions.

Columbus & BexleyColumbus Public Health issues sewer and water service permits inside Columbus city limits, including Bexley. Sewer-lateral permits are typically $150–$285.

Franklin County (unincorporated)Franklin County Public Health covers unincorporated areas and some smaller jurisdictions. Different permit fee structure, similar inspection sequence.

Other counties — Fairfield County (Lancaster, Pickerington), Pickaway County (Circleville), and Delaware County each maintain their own health departments. Wooley pulls permits in all of them as part of standard project setup.

Right-of-way permits — when the trench crosses a sidewalk, curb, or roadway, a separate ROW permit is required from the municipal engineering office. Traffic-control plans, sidewalk closure notices, and pedestrian routing are submitted with the application.

Inspection sequence — open-trench inspection before backfill (mandatory for most jurisdictions), pressure-test verification (water), camera-scope or air-test verification (sewer), and final restoration sign-off. Wooley schedules and meets every inspection.

FAQ

Excavation Work — Frequently Asked Questions

How long does an excavation job take in Columbus?+

A typical residential spot repair is one working day on site once the permit is pulled and the locate clears. A full lateral replacement or new install is two to four working days on site, plus inspection scheduling. Permit and OUPS-locate lead time adds 3 to 7 business days before the dig starts. Larger commercial scopes run on their own schedule and are quoted with a written timeline.

Do you handle the permit pull?+

Yes — permit-pull is included in every Wooley excavation quote. We file with the correct jurisdiction (Columbus Public Health, Franklin County Public Health, or the corresponding county / city office), pay the fee at submission, and pass the cost through line-item on the invoice with no markup. Right-of-way permits where the trench crosses public property are handled the same way.

What surface restoration is included in the quote?+

Lawn restoration — topsoil, seed, and straw mulch — is included on every job. Concrete sidewalk patches and asphalt driveway patches are quoted line-item; we coordinate with a paving partner where the spec requires it. Stamped concrete, pavers, and decorative landscaping are project-priced and discussed at the site visit. We never quote a job without putting restoration scope in writing.

Can you work on tight Bexley lots?+

Yes. Our mini-ex fits through a standard 36-inch gate and turns inside a 12-foot working corridor. We have excavated on hundreds of Bexley properties with mature trees, side-yard easements, and very narrow access. When the access is genuinely impossible for the mini-ex, we have hand-dug short runs (typically <10 feet) rather than damaging the property.

How deep do you dig for water vs. sewer lines?+

Water lines: minimum 48 inches below grade in Ohio — that is the published frost-depth requirement. We typically install at 54 inches to give a buffer. Sewer lines: depth varies by the existing connection point. New laterals tie into the city main at whatever depth the main runs (usually 6–10 feet), then rise toward the structure at the code-required 1/4-inch-per-foot slope. We confirm depth on the site visit before quoting.
