# SewerReplacement.ca

> Repair, reline or replace — the Canadian decision guide to sewer line replacement, method by method. SewerReplacement.ca is part of the HAUSE Sewer network — an independent Canadian information and service-request network (not a contractor). Contact: sewers@hause.ca, 403-679-3100.

Sewer line replacement renews the pipe between a house and the municipal main along its whole length, by open-cut excavation, pipe bursting or full-length cured-in-place relining. SewerReplacement.ca helps Canadians decide whether a line needs repair, relining or replacement, choose the method that fits the defect and the site, and supervise the work. It is an independent information network, not a contractor.
