Underground Plumbing

Trenching & Site Prep for Utility Lines, Septic, and Water Systems

Installing underground plumbing requires more than a shovel. It takes precision, experience, and the right equipment to dig safe, code-compliant trenches that protect your utilities for the long haul. That’s where Earth Shaping LLC comes in.



We provide professional underground plumbing prep services across Canaan, Madison, and Southeastern Indiana, working with homeowners and contractors to excavate and backfill trenches for water lines, sewer systems, septic tanks, and drainage pipes — all done right the first time.

What We Handle

We specialize in excavation and support services related to underground utility installation:

Trenching for Water & Sewer Lines

We dig straight, level trenches to proper depth and slope for residential water mains, sewer pipes, and laterals.

Septic Tank Excavation

Excavation and grading for new septic tank systems, leach fields, and repair access.

Underground Drainage Pipe Installation

Trenching for stormwater piping, downspout extensions, culverts, and property-wide drainage improvements.

Utility Conduit Prep

We provide trenching for conduit runs for electric, gas, or internet lines as part of new builds or upgrades.

Backfilling & Compaction

After inspection or installation, we backfill trenches with proper compaction to prevent settling and sinkage.

Site Grading for Access & Protection

We slope surrounding ground to keep surface water away from newly installed plumbing or septic systems.

Who We Work With

We support a wide range of underground utility projects, including:



  • Homeowners installing or upgrading septic and water systems
  • Plumbing contractors who need trenching and backfilling support
  • Builders and general contractors prepping sites for new home construction

Whether you’re building from scratch or making critical repairs, we make sure your underground infrastructure has a solid foundation.

Frequently Asked Questions

  • How deep do you dig plumbing trenches?

    We follow local code and contractor specs. Typical water and sewer lines require trenches 18–36 inches deep, with proper slope and base support.

  • Do you install pipes?

    No — we provide excavation, trenching, and backfill services only. Licensed plumbers or utility contractors handle the pipework itself.

  • Can you dig around existing utilities?

    Yes. We call 811 before every dig and use caution when working near known underground lines.

  • Do I need a permit for this work?

    We’ll help you determine if a permit is needed based on location and project type. We can coordinate with your contractor to ensure compliance.
