> New sewer services for infill, multiplex, suite and laneway builds across Canada — the city process, sizing, costs and timelines. NewSewerLines.com 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.

A new sewer service connection joins a new or densified building to the public sewer: a tap on the main, a public segment to the property line and a private building sewer to the building. For infill, suites and multiplexes, the city decides who builds the public side, whether the old service may stay and what it charges; the plumbing code decides the minimum size.
