As winter gives way to spring thaw, some Ottawa residents are bracing for the challenges of meltwater after an exceptionally snowy season. In this blog, we’re taking a closer look at sump pumps, an essential tool in keeping your basement dry. By understanding the role of your sump pump and integrating electrical safety measures, you can better protect your home from costly flooding.
What’s a sump pump and how they work
A sump pump is an electrical device designed to remove excess water from your home. Typically installed in the lowest part of your basement or crawl space, it is activated when water levels rise due to heavy rains or melting snow, and works by collecting water in a sump pit and then pumping it away from your home’s foundation. Once the water level drops, the pump shuts off until it’s needed again.
Sump pump options: Choosing the right system for your home
There are several types of sump pumps available, each with unique features to suit different needs:
Submersible sump pumps: Installed directly into the sump pit and operating underwater, these pumps tend to be quieter and are ideal for finished basements and deep pits. They also reduce the risk of electrical hazards due to their water-friendly design, however, they can be more challenging to service and may incur higher installation costs.
Pedestal sump pumps: With the motor mounted above the sump pit, these pumps are easier to service, generally offer a longer lifespan, and are simpler to install, making maintenance straightforward. However, they tend to be noisier, may not perform well in deeper pits, and their above-ground components can be more susceptible to damage from debris or weather conditions.
Backup sump pumps: Power outages can occur during severe weather, exactly when your sump pump is needed most. Since submersible and pedestal options rely on electricity to run, consider investing in a battery backup system, water-powered alternative, or a generator capable of running your sump pump for up to 72 hours.
Combination sump pumps: These systems integrate both a primary electrically-powered sump pump and a backup option, ensuring seamless operation during power outages. While they offer the convenience of a single unit and automatic switching, they can be more complex and expensive to install.
In addition to choosing the right pump for your basement's layout and water volume during heavy rainfall or snowmelt, you might also consider installing a sump cover to help keep debris out and a sump pump alarm for early detection of pump failure. Consulting with a professional can help you determine the best system and accessories for your home’s unique needs.
Who is most at risk of flooding in Ottawa?
A good sump pump is a must for most homeowners, especially those in flood-prone neighbourhoods. Here are some key factors that might make your home more susceptible to flooding:
- Low-lying areas: Homes located in neighbourhoods near the Ottawa or Rideau Rivers or other low-lying regions are more susceptible to flooding during heavy rainfall or rapid snowmelt.
- Older homes: Many older properties, particularly those with basements that may not have been designed to handle modern water intrusion challenges, are at increased risk.
- Properties without upgraded systems: Homes lacking regular maintenance or without updated sump pump systems, including backup power options, are more likely to experience flood-related damage.
- Urban areas: Increased surface runoff in densely populated areas can contribute to localized flooding issues, making it important for urban residents to stay vigilant during periods of heavy precipitation.
Take a look at this interactive floodplain map by the Conservation Authorities in collaboration with the City of Ottawa, which not only identifies known riverine flood hazards for any property or area but also plays a key role in directing land use planning through the Official Plan and Zoning By-Law, informing risk assessments and adaptation planning, and guiding emergency preparedness and response plans. For more information, visit their website.
Recognizing the risk many Ottawa homeowners face, the City has updated its Residential Protective Plumbing Program, which provides financial assistance to eligible homeowners up to $3,000 for a new sump pump installation or $1,500 for upgrades to an existing pit. These changes are intended to help residents reduce flood damage risk.
Electrical safety and sump pumps
Given that sump pumps are electrical devices, proper safety measures are essential. Flooding can pose a serious electrical hazard if water comes into contact with your pump or other electrical systems. To protect yourself and your home:
- Use ground fault circuit interrupter (GFCI): To minimize the risk of electrical shock, a sump pump should be connected to a GFCI outlet. This safety device automatically shuts off power if it detects current flowing along an unintended path, such as water or a person, helping to prevent serious injury.
- Know when to disconnect the power: If flooding becomes severe enough for water levels to reach electrical outlets, panels or equipment, avoid entering your basement as it could cause an electrical shock. Instead, contact Hydro Ottawa at 613-738-0188 immediately to have your electricity safely turned off. We will waive our connect/disconnect fees for anyone impacted by flooding.

Sump pump maintenance
Regular inspection and maintenance of your sump pump is important. Follow these tips to ensure your system is in top shape:
- Regular testing: Pour a bucket of water into the sump pit to verify that the pump activates correctly.
- Keep the pit clear: Remove debris that could clog the pump and compromise its performance.
- Inspect the discharge line: Ensure that the water is being directed away from your home’s foundation and that the line is free of obstructions or ice during the colder months.
- Professional servicing: Consider having a qualified technician inspect your sump pump annually, particularly before the spring thaw.
Beyond the sump pump: Emergency preparedness
While a sump pump is an excellent first line of defense against basement flooding, it is only one part emergency preparedness. Here are a few additional tips to help you stay safe:
- Monitor weather updates: Stay informed of weather conditions during spring thaw. Local forecasts can provide timely warnings about potential flooding.
- Review your home’s emergency plan: Ensure that your family knows the safe exit routes and that emergency contact numbers are readily available. If you don’t have an emergency plan or checklist, our website can get you started.
- Plan for extended outages: Establish backup power solutions not only for your sump pump but also for other essential home systems.
- Get outage alerts: Make sure you’re registered for Hydro Ottawa’s outage alerts to receive real-time updates during severe weather. Being alerted about power outages can help you prepare for flooding risks and take proactive measures to safeguard your home.
