Utility Trenches
Utility Trenching in Edison: Water, Sewer, Electric & Gas
Edison Excavation digs trenches for water service lines, sewer laterals, electrical conduit, and gas runs, including gas lines to standby generators, throughout the Edison area. We request the NJ One Call markout, cut a clean trench to the depth your plans or code require, and close it in compacted lifts. Your plumber or electrician makes the connection, and we take care of the ground.
How each trench is built
A trench is easy to do poorly. Ours are straight, safe, and closed so neatly you can barely tell it was there.
Depth and Fall Held
Water lines go below the NJ frost line, roughly 36 inches. Sewer laterals need consistent fall. Laser grade control holds depth and slope so the pipe lays right the first time.
Proper Bedding and Backfill
Bedding sand beneath the pipe, hand-placed backfill around it, warning tape where the utility calls for it, then backfill compacted in lifts so the lawn doesn't sink into a stripe next spring.
Markout and Trench Safety
An NJ One Call 811 markout comes before every dig, without exception. Where depth demands it, a trench box or benched walls keep the trench safe for the trade working in it.
One clean line across the yard
Many trenches are dug with a backhoe that rips a truck-wide path across the yard. We use a mini excavator with a narrow bucket, so a conduit run to a detached garage, EV charger, generator pad, or pool equipment leaves one tidy line instead of a construction zone. Spoil sits on protection boards, topsoil stays separate, and the trench closes the way it opened.
Where we work
We work for homeowners and directly for the trades. The trench opens on the agreed day, holds the spec, and doesn't sit open waiting on anyone. If you already have a plumber or electrician lined up, we'll coordinate the timing with them directly.
Trenching cost per linear foot
Typical New Jersey ranges, for budgeting only: about $5 to $25 per linear foot for residential trenching in open ground. A shallow conduit run through a lawn is at the low end. A water service below the 36-inch frost line, or any run crossing a driveway or walkway, is at the high end, and cutting and patching asphalt or concrete roughly doubles the per-foot cost.
Length, depth, soil, and surface restoration set the price, along with how much hand digging the markout requires near existing lines. Tell us what's going in the ground and where it runs. We'll walk it, point out complications up front, and put one firm number in writing.
What happens after you call
From the site walk to the final cleanup
1. Site Walk
We visit the property by appointment, check access and any constraints, and go over your plans or what you have in mind.
2. Marking & Layout
The layout is set on the ground with laser accuracy. Depths, lines, and elevations are marked before any digging starts.
3. The Work
The right machine for the access comes in, ground protection goes down where needed, and disturbance to lawns, trees, and hardscape is kept to a minimum.
4. Clean Handover
You're left with a site ready for the next step and a yard that's still in one piece.
Frequently Asked Questions
No. Regulated connections belong to your licensed plumber, gas fitter, or electrician. We open the trench, bed it, and backfill after their work passes inspection. That division is standard on these jobs, and we time the dig with your trade so the trench is open as briefly as possible.
As deep as the job requires. Water services run below the frost line, about 36 inches in New Jersey. Sewer laterals follow the fall on your plumber's plan. Electrical depth comes from code and your electrician's spec. We dig to the number, not a guess.
A narrow, compacted line, not a scar. Topsoil is kept separate from trench spoil, backfill is compacted in lifts so the line doesn't settle, and the surface is raked out. On finished lawns, ground protection goes down along the machine path too.
As a New Jersey market range, not a quote: residential trenching in open ground usually runs $5 to $25 per linear foot. Cutting through asphalt or concrete roughly doubles the per-foot cost, and deeper water-line trenches below the frost line sit at the high end. We walk the run and give one firm number.
Yes. We trench from the meter or tank to the generator pad at the depth your installer or plumber specifies and backfill after the line is inspected. The gas piping and connection remain with your licensed plumber or generator installer.
Yes, whenever the ground can be opened safely. A water service or sewer lateral that fails in January still has to be dug up. The trench is backfilled and compacted the same way, with final topsoil and seed in spring.
