Water line locating in Dorval before replacing a water service line

A different situation from Montreal

Unlike several Montreal boroughs, Dorval was among the related municipalities where the City of Montreal indicated there was no lead in service lines, according to information published during its screening campaign (1). Replacing a water service line in Dorval is therefore mostly driven by other causes: wear, breakage, freezing or work on the property.

Whatever the reason, the private portion remains the owner's responsibility, and its path is rarely documented.

What we locate before excavation

• The private water line and its estimated depth
• The sewer connection, often running parallel
• Electrical and telecom cables crossing the trench
• Roots and structures in the way, depending on what the ground penetrating radar reveals

Limiting the impact on a landscaped lot

Dorval properties often have mature landscaping: trees, hedges, paved driveways. A precise path makes it possible to limit excavation and choose the best opening point, in coordination with your plumber or contractor.

Frequently asked questions

How do I know where my water service line runs? It usually enters the building through the wall facing the street. The survey confirms its path to the shut-off valve and its estimated depth.

Can a copper line be detected easily? Yes. Copper is metallic, which makes it possible to follow it with radio detection from an access point, such as the main valve in the basement.
