I'm looking at buying a new home with a rear basement walkout that has a drain in the ground just outside. House inspector is adamant the drain should be hooked up to the sump pump, but the builder hooked it up to the sewage line instead and says that's the way it should be according to the City as well.

What is correct code for Edmonton and/or what are your professional thoughts?

Hi Clara

Is the drain a storm drain or sanitary sewer drain ?

Hooking it up to the storm drain is appropriate and works well, as it will not require power and should work effectively as long as the drain is kept clear of debris. If it is not a storm drain, the City has made it clear in many neighborhoods that all storm water connections should be to sumps or in the case of downspouts, directed to the surface away from the home.

You are responsible to control the storm water within the property as each lot has a drainage plan that was put forth with the application to build the home in the first place.

In any case, City of Edmonton planning can weigh in on the conversation and explain current guidelines - call 311.

You mention the 'house inspector'. Is that the City Plumbing Inspector, City Grading Inspector or a home inspector?

My new Edmonton home has a slightly lowered entry which has some granular, road crush and flagstone pavers and no drain. It never collects any water either under spring melt of heavy rain conditions. The grading inspector asked me about it when he conducted his final inspection and once I told him how it performed he was OK with it not having a drain which would ordinarily be linked to the weeping tile and then the sump.

There's nothing in the Code to suggest that it requires a drain with the exception of a grading article which reads that 'the site shall be graded so that water will not accumulate adjacent to a building'.
