Sewers and drains in Kanata North & Kanata Lakes
Kanata grew in stages. Beaverbrook dates from the late 1960s and 70s and has the cast iron drains and copper lines of that era. Kanata Lakes and Heritage Hills filled in through the late 1980s and 1990s (for example, homes on Knudson Drive from around 1992), and Morgan's Grant and newer streets kept going into the 2000s.
Most of these homes have separate storm and sanitary sewers, a sump pit fed by weeping tile, and a finished basement. That's where the risk is: water arriving faster than the system can move it.
City works on your street
Kanata's west end has a flooding history the City has spent real money fixing. Severe storms in 2002 and 2009 flooded about 225 and 1,200 homes across Kanata, Stittsville and Carp. In Glen Cairn in 2009, storm water got into the sanitary sewers through manhole vents and backed up into basements as sewage. The City finished $35 million in fixes afterwards: regraded roads, new catch basins and pipes, and a storage pond near Castlefrank Road and Winchester Drive.
The City's side is better than it was. Your side still matters: a backwater valve stops sewage coming back up your drain if the sanitary sewer surcharges, and a battery backup sump pump keeps groundwater moving when a storm takes the power out. Homes built before 2004 and 2012 can get rebates of up to $1,500 to $3,000 and $1,000 for these.
Storms and basement flooding
The July 2026 Canada Day storm hit the west end hardest, with up to 167 mm of rain in places. Basements with an untested sump, or a sump with no battery backup, were the ones that flooded.

What's in your house, by the year it was built
The year a home was built tells us most of what's behind the walls and under the floor. Builders used the materials of their time, so one subdivision can share the same weak spots. Here's what we usually find in Kanata North:
| Built | What's usually in the walls and under the floor | What to watch for |
|---|---|---|
| 1958 to mid-1970s | Copper water lines, cast iron stack and building drain, clay or early plastic lateral | Cast iron rotting under the slab; roots at lateral joints; no backwater valve |
| Late 1970s to mid-1990s | ABS drains, copper or Poly-B (grey "PB2110") supply lines, sump pits in many suburbs | Poly-B fitting failures and insurance limits; first-generation sump pumps; no backwater valve |
| Mid-1990s to 2007 | ABS drains, copper, PEX or Kitec-style supply pipe, sump pit and finished basement | Brittle fittings on early plastic supply systems; sump with no battery backup |
| 2008 and newer | ABS drains, PEX supply, sump pit, often a backwater valve from new | Sump pumps never tested; discharge lines that freeze |
Buying a home here
Before you firm up an offer, ask for:
- A sewer camera inspection of the lateral from the house to the street. Replacing a failed sewer line is one of the biggest repair bills a homeowner can face.
- The water pipe material where it enters the house (lead before 1958; Poly-B in some 1980s and 1990s homes).
- A look at the sump and floor drain: age of the pump, battery backup, and whether there's a backwater valve.
- Any history of water in the basement, and what was done about it.
Already own here?
- Test your sump pump each spring and fall, and check the backup battery's age.
- If a floor drain has backed up even once, get the line cameraed before the next storm.
- If the City sends a renewal notice for your street, call us before their crew reaches your connection.
How old plumbing ties into new
Most homes here are a mix of eras: an original cast iron stack with an ABS bathroom added in the 1990s, or copper lines patched with PEX. That works when the joins are done properly. Cast iron to ABS needs the right transition couplings and support so the old pipe doesn't crack under the new. Copper or Poly-B to PEX needs the right fittings, not a quick crimp onto pipe that's already brittle. And a backwater valve has to go into the building drain at the right spot, with an access cover you can actually reach.
Why call Michael
