- Make sure your downspouts and extensions don't leak.
- Disconnect any downspout connections that drain directly into the sanitary sewer system.

- Maintain your approved lot grade plan. Do not change this when you landscape your property. Sump pumps should discharge water at least 1.5 metres (5 feet) from the foundation wall.
- If your sump pump discharges on the ground, place a splash pad below where the sump pump discharge pipe comes through the foundation wall.
- Use long pipes to drain away sump pump discharge.
- Slope the ground below the discharge pipe down and away from the foundation wall at a minimum of 5 per cent grade.
- Never turn off your sump pump.
- Do not hook up your sump drainage to the sanitary sewer system. The sanitary sewer system is designed to manage normal flows of sewage and not rainwater or water from sump pumps.
- Do not let your sump pump drain water onto the sidewalk. Resulting algae build-up creates a slippery, unsafe surface. This can be a liability issue for the homeowner and the County.
- Consider a backup battery system from your sump pump in case of power outages.
For homes built prior to 2001, without a sump pump installed, contact Utilities at 780-467-7785. Our staff are will work with homeowners to find alternatives to unauthorized connections.
