From water main connections to full sewer system installation — KD Excavating handles every underground utility from trench to tie-in, done right the first time.

The Service

What Is Water & Sewer Work?

Water and sewer installation is among the most critical and technical work on any construction project. An improperly installed water line leads to contamination, pressure loss, and costly repairs. A poorly graded sewer line backs up, floods, and creates health hazards. This is work that must be done by an experienced crew with the right equipment.

KD Excavating has extensive experience installing and repairing underground water and sewer systems for residential, commercial, and municipal clients across Ottawa. We handle the full scope — trenching, pipe installation, proper grading, backfill, and compaction — coordinating with the City and utilities to ensure every connection meets code and passes inspection.

Our Process

How It Works

01
Utility Locates
Before any digging begins, we request full utility locates to identify existing underground services and ensure safe excavation.
02
Permits & City Coordination
We handle permit applications and coordinate with the City of Ottawa inspectors — you don't have to navigate the bureaucracy alone.
03
Trenching & Installation
Trenches are excavated to the proper depth, pipe is installed at the correct grade, and all connections are made to code.
04
Backfill, Compact & Inspect
Trenches are backfilled in proper lifts and compacted to prevent settling. Final inspection is coordinated before site restoration.

FAQ

Frequently Asked

Do I need a permit for water and sewer work?
Yes — any connection to the municipal water or sewer system requires a permit and inspection from the City of Ottawa. We coordinate this entire process on your behalf.
How deep are water and sewer lines in Ottawa?
In Ottawa, water service lines are typically installed 1.8–3 metres below grade to protect against frost. Sewer lines are graded for drainage and vary by distance and elevation.
What if I hit an unexpected underground obstacle?
We request utility locates before every dig. If unexpected obstacles are encountered, we assess and communicate options immediately — no surprises on your invoice.
