The City of Burlington says a sump pump must discharge outdoors and the water must remain on the owner's property. It cannot connect to the public sewer, flow onto neighboring property or discharge in the City right of way. The outlet also needs to keep water from returning to the foundation or freezing across a walking or driving surface. If the pump cord cannot reach an approved outlet, Burlington says a permitted outlet approved for a wet location is needed.
What to know
- Keep sump water on your own property.
- Do not connect a sump pump to Burlington's public sewer.
- Do not discharge into a right of way or onto a neighboring property.
- Plan for winter freezing and a safe electrical supply.
The Burlington rule
Burlington's Plumbing and Mechanical guidance states that sump pumps discharge to the exterior and remain on the owner's property. The same guidance prohibits a connection to the public sewer and prohibits discharge onto neighboring property or into the City right of way.
That rules out several shortcuts. A hose cannot simply end at the sidewalk, curb, street or lot line. The job needs a discharge point on the property with enough room and slope to handle the water without sending it back toward the basement.
Choosing an outlet on the property
A useful outlet releases water where it can spread or drain without eroding soil, saturating the footing, flooding a lower door or creating a dispute with a neighbor. The exact distance from the house depends on grade, soil, landscaping and the amount of water the pump handles.
Buried pipe needs continuous fall where possible and a visible, serviceable termination. A drywell or underground dispersal system is not automatically suitable for every lot, especially in saturated or frozen soil. Before excavation, use Dig Safe and check property and utility constraints.
- Keep the termination visible and serviceable
- Avoid low areas that send water back to the foundation
- Protect walkways and driveways from ice
- Do not bury an unknown outlet beside the house
Electrical and permit considerations
Burlington says no plumbing permit is required simply to place a sump pump where its manufactured cord reaches an approved outlet. If no approved outlet is within reach, an outlet must be installed using permits and devices approved for wet locations.
Do not solve the problem with a permanent extension cord. Have the power supply, pump, alarm and backup arrangement included in the installation scope when electrical work is needed.
Designing for a Vermont winter
A pump may work perfectly while its exterior line is frozen. Low spots, undersized pipe, buried outlets, flexible hose and snow accumulation can hold or block water. The installation should drain between cycles where the site allows and should have an outlet that can be checked after heavy snow.
Battery or water-powered backup does not solve a shared blocked pipe. Ask where both pumps discharge and what happens if the exterior line freezes.
Frequently asked questions
What happens if a discharge is routed incorrectly?
Beyond the municipal issue, misrouted discharge creates practical problems: water returning to the foundation it just left, ice on a walk or driveway, or a dispute with a neighbour receiving it. Burlington guidance requires the discharge to stay on your own property and out of the public sewer and right of way.
Can a sump pump discharge into a Burlington storm drain?
Do not assume it can. Burlington's public guidance says the discharge must remain on the owner's property and must not enter the City right of way or public sewer. Confirm any unusual connection directly with the City's permitting staff before installation.
Does Burlington require a permit for the sump pump itself?
The City says no plumbing permit is required when a sump pump is placed where its manufactured cord reaches an approved outlet. A new electrical outlet requires the appropriate permit and wet-location installation.
