Question 1

Is a sump pump part of every interior drain system in Ottawa?

Accepted Answer

A sump pump is required by Ontario's Building Code only where gravity drainage is not practical (clause 9.14.5.2). Whether that condition applies depends on where your foundation sits relative to the storm sewer or a suitable discharge point, and a contractor has to assess that for your house. An interior drain system collects water that enters at the base of the foundation walls and channels it to a collection point.

Question 2

Who should I hire for an interior drain in Westboro?

Accepted Answer

For an interior drain system in Westboro, you are looking for a waterproofing contractor who can also bring in, or confirm they work with, a licensed plumber for the parts of the job that connect to your home's plumbing. Here is why that matters. Plumber is a compulsory trade in Ontario under O. Reg. 876/21. The province says you cannot engage someone to do compulsory trade work unless they are authorized to do it.

Question 3

Where does the water from an interior drain end up in an Orleans house?

Accepted Answer

An interior drain channel collects water that enters along the base of the foundation walls and directs it to a sump pit. From the pit, a sump pump pushes the water out of the house. Where that discharge goes is the part that varies. Ontario's Building Code (9.14.5.1) says foundation drains must discharge to a sewer, a drainage ditch, or a dry well. For a sump pump, the City of Ottawa advises connecting it to the storm sewer or discharging to the ground at least 1.2 m from the foundation.

Question 4

Is a City of Ottawa permit needed for an interior drain system?

Accepted Answer

The sump pit and pump in an interior system are protective plumbing devices, and the City of Ottawa says a building permit is required to install them, before the work starts. Whether the drain channel itself counts as "drain tile replacement" on the City's permit list is not stated, so ask the City about that part. The drain channel connects to a sump pit and the pump discharges somewhere, so there is a plumbing component: ask whether a licensed plumber does or signs off that part.
