Steps we Take

Our Utility Work Process

1. Site Evaluation & Dig Safe Mark-Out

Before any digging begins, we conduct a full site assessment, review plans, and secure Dig Safe utility mark-outs. This prevents damage to existing lines and ensures a safe, compliant start to every project.

2. Precision Excavation & Trenching

We excavate to the correct depth, slope, and grade using laser equipment and trench safety systems. Whether it’s water, sewer, drainage, or conduit trenching, we maintain clean and stable trenches throughout the install.

3. Utility Bedding & Base Prep

Proper trench bedding is critical. We install stone or sand bedding to support pipes, prevent settling, and give the system a solid foundation.

4. Installation of Water, Sewer, and Drainage Systems

Our team installs all underground utilities, including:

  • Water service lines

  • Sewer lines and tie-ins

  • Drainage systems

  • Culverts and catch basins

  • Electrical and communication conduits

  • Precast manhole installations

We ensure proper slope, alignment, and all required connections.

5. Backfilling & Compaction

After installation, we backfill in lifts with quality material and compact thoroughly to prevent future settling or pipe movement. This step is essential for long-term performance.

6. Final Grading & Site Restoration

We finish the job with clean final grading and site restoration. Driveways, lawns, and work areas are left neat and ready for the next phase of construction.

7. Inspection & Project Approval

WM Earthworks coordinates town inspections and ensures all installations meet local codes and engineering standards before the project is closed out.
