What to do if you notice a problem with your water and sewer system?

If you notice a problem with your installation, you can call on a Lesage Excavation expert, who will come and perform a camera inspection in order to give you an overview of the situation as well as the actions to take to correct it. Generally, this involves repairing an existing duct or replacing it (if it is too old, for example).

Steps to replace your sewer system

  • Excavation of trench to municipal boundary
  • Removal of old conduits and aqueducts
  • Reconnecting new conduits with mechanical unions
  • Recoating new conduits with crushed stone
  • Trench backfill
