If you are wondering where a sump pump should discharge, the short answer is: onto a suitable area of your own property where water can drain away from the house without creating a new problem. The outlet should not send water back toward the foundation, pool beside the home, erode the yard, or flow onto a neighbour’s property or a public walkway.
For homes in Collingwood, the Town says sump pumps should discharge onto the lawn or into the ground, and never into a basement floor drain. In The Blue Mountains, the Town recommends a route about 6–10 feet from the house and says not to direct the water onto a neighbour’s property. The exact route still depends on your lot’s grading and any approved drainage connections.
Local guidance at a glance
| Municipality | Local guidance | What it means for your outlet |
|---|---|---|
| Collingwood | The Town directs residents to discharge sump-pump water onto the lawn or into the ground, never into a basement floor drain. Its Property Standards By-law also bars discharge onto an entranceway, walkway, stairs, public sidewalk or neighbouring property. | Use a landscaped area on your own lot that carries water away from the house and does not create ponding, erosion or an icy path. |
| The Blue Mountains | The Town says to keep the sump pump off the sanitary sewer, recommends running the hose 6–10 feet from the house, and says to avoid a neighbour’s property. | Extend the outlet far enough to reduce water returning to the foundation, while keeping the discharge on your property and within the site’s drainage design. |
The safest starting point: your own yard, away from the foundation
A sump pump collects groundwater around the foundation and sends it outside through a discharge pipe or hose. The outlet needs to move that water far enough away that it does not immediately seep back toward the footing or basement.
A suitable outlet area is usually a landscaped part of your own property that can receive and disperse the water. A splash block or similar surface feature may help spread the flow and reduce soil erosion. The ground should carry water away from the home and should not create standing water, damage a garden or affect a neighbouring lot.
The Blue Mountains recommends running the sump-pump hose 6–10 feet away from the house. Collingwood’s homeowner guidance does not give a fixed distance on its wastewater page; it says to discharge onto the lawn or into the ground. In either town, the right placement depends on the slope, soil, lot size and the location of walks, driveways, property lines and existing drainage routes.
Keep sump-pump water out of the sanitary sewer
Sump-pump water is groundwater, not household wastewater. It should not be sent into a basement floor drain, laundry tub, sanitary cleanout or other connection to the sanitary sewer.
The Town of Collingwood says never to discharge a sump pump into a basement floor drain. The Blue Mountains says a sump pump or foundation drain connected to the sanitary sewer through a floor drain, laundry tub, cleanout or another direct or indirect connection is illegal under the Town’s Sewer Use By-law and the Ontario Building Code.
A storm sewer is a separate system from a sanitary sewer, but that does not mean any nearby drain or pipe is an approved sump-pump outlet. Collingwood’s published Development Standards document describes a residential storm connection for some sump-pump systems and a landscaped splash pad where such a connection is not available. The document is dated July 2007 and addresses development design; it does not confirm which connection, if any, is approved for an individual existing home. Check the property’s drainage plan and confirm with the Town before connecting to or changing an underground line.
Places to avoid
Do not point the outlet:
- back toward the foundation or into a basement window well;
- onto a neighbour’s property;
- across a public sidewalk, walkway or stairs;
- onto an entranceway or another area where water can pool or create a hazard; or
- into a pipe, catch basin or sewer connection unless you have confirmed that it is the approved outlet for your property.
Collingwood’s Property Standards By-law specifically names entranceways, walkways, stairs, public sidewalks and neighbouring properties as places where sump-pump drainage must not be discharged. In cold weather, also avoid routing water over a driveway, path or other surface where it could freeze and become slippery. A line that works in summer may create an ice patch during a South Georgian Bay winter thaw.
What about a cottage or seasonal home?
At a seasonal home, the discharge route still needs to work when nobody is there to notice a problem. Before closing the property for an extended period, check that the outlet is visible, connected and free of leaves or other obstructions. If the pump may run during winter or spring thaw, make sure the discharge point is not buried under snow or positioned where it will repeatedly freeze over.
If you are not sure whether the sump pump is meant to remain powered while the home is closed, or whether an existing line is approved, check the pump instructions and ask a plumbing professional to inspect the arrangement. Do not guess at a winter shutdown plan for a system that protects the basement from groundwater.
How to tell if the discharge route needs attention
Take a closer look if you notice water collecting beside the foundation, a constantly damp area near the outlet, soil erosion, a neighbour’s yard becoming wet, or the pump running for long periods while water appears to return toward the house. A blocked or disconnected discharge line can also leave a pump running without moving water away from the home.
If you do not know where an older discharge line goes, have it traced before changing it. A plumber can inspect the private plumbing and discharge piping. The municipality can confirm whether a connection to its storm or sanitary system is approved for that address.
Frequently asked questions
How far from the house should a sump pump discharge?
The Town of The Blue Mountains recommends a distance of 6–10 feet from the house. Collingwood’s published homeowner guidance says to discharge onto the lawn or into the ground but does not give a set distance on that page. In both communities, the outlet must keep water from cycling back toward the foundation and must follow the drainage requirements for the property.
Can a sump pump discharge into a floor drain?
No. Collingwood says sump pumps should never discharge into a basement floor drain. The Blue Mountains also identifies connections through floor drains, laundry tubs and sanitary cleanouts as illegal sump-pump connections to the sanitary sewer.
Can I connect my sump pump to a storm sewer?
Only if the connection is approved for your home and is part of the property’s drainage design. Do not connect a sump pump to a pipe or street catch basin because it looks convenient. Check the original lot or grading plan and confirm the permitted connection with the municipality before doing the work.
Can the discharge hose run across a sidewalk or onto my neighbour’s property?
In Collingwood, the Property Standards By-law says sump-pump drainage must not be discharged onto a public sidewalk, walkway, stairs, entranceway or neighbouring property. The Blue Mountains also tells residents not to direct the hose onto a neighbour’s property. Choose a route that keeps the water on your lot and does not create a winter ice hazard.
Are sump-pump bypass valves allowed in The Blue Mountains?
The Town of The Blue Mountains says a bypass valve on a sump-pump discharge pipe or hose is illegal there. If your home has one, contact a qualified plumbing professional about the correct arrangement for your property.
Need help with a sump-pump discharge line?
If your sump pump is connected to an unknown pipe, water keeps collecting near your foundation, or the outlet needs to be redirected, arrange an inspection before the next heavy rain or spring thaw. A plumber can assess the pump and the private discharge line; municipal approval may be needed for any connection to public infrastructure.
