Water has to go somewhere. When it pools around your foundation or runs off your roof onto the driveway, that water needs a proper path away from the house. A storm sewer connection in Kingston gives it one. It ties your property drainage into the municipal storm system, so rainwater and snowmelt drain away instead of sitting where they cause damage.
We have handled this kind of work across Kingston and Frontenac County for more than 20 years. So in this post, we will walk you through when you need a storm sewer connection, how catch basins fit in, and what the job actually involves. We will also cover permits, common problems, and cost.
What a storm sewer connection actually does
A storm sewer carries surface water. That means rain, snowmelt, and roof runoff. It does not carry wastewater from your toilets or sinks. That is a separate job for the sanitary sewer.
A storm sewer connection in Kingston links your property drainage, things like catch basins, downspouts, and foundation drains, to the municipal storm main under the road. Since storm and sanitary systems are kept separate, you cannot legally pipe one into the other. Mixing them overloads the system and can push sewage back up.
In short, a proper storm connection keeps clean rainwater in the storm system and dirty wastewater in the sanitary system. That separation matters for your home and for the whole neighbourhood.
Storm sewer vs sanitary sewer
People mix these two up all the time, so here is the simple version.
- Storm sewer: handles rain, snowmelt, and surface runoff. It usually drains to a creek, pond, or lake.
- Sanitary sewer: handles wastewater from inside the house. It goes to a treatment plant.
Since these systems serve different jobs, they use different pipes and different connections. Our team handles both under our water and sewer installation and repairs service, so we can sort out which one your property actually needs.
Signs your Kingston property needs a storm connection
Not every home needs a dedicated storm sewer connection. However, some clear signs point to a drainage problem that one can fix. Watch for these.
- Water pools near the foundation after rain and takes hours to drain.
- Downspouts dump right beside the house instead of carrying water away.
- Your basement stays damp or floods during heavy storms.
- Ice builds up along walkways and the driveway in winter.
- Low spots in the yard hold standing water for days.
These problems often come together. For example, a disconnected downspout floods a low spot, and that low spot then pushes water back toward the foundation. So the real fix usually means looking at the whole drainage picture, not just one pipe.
Downspouts and foundation drains
Downspouts are the biggest culprit we see. Many older homes still dump roof water at the base of the wall. That water soaks the soil and finds its way into the basement.
Foundation drains, sometimes called weeping tile, sit around the base of your footings. They collect groundwater and carry it away. When those drains fail or connect to nothing, water backs up against the wall. If you suspect a foundation drainage issue, our guide on weeping tile and drainage explains how these systems work and when they need replacing.
How catch basins tie into the system
A catch basin is a boxed drain set into the ground, usually with a metal grate on top. Water runs across the surface, drops through the grate, and enters a pipe below. That pipe carries it to the storm sewer.
Catch basins work well on driveways, laneways, and low spots that collect water. Since they trap grit and debris in a sump at the bottom, they also keep the storm pipe from clogging. That said, they need occasional cleaning to keep working.
On larger sites, we tie catch basins into a network of pipes and connect the whole thing to the municipal main. This kind of surface drainage often overlaps with road and site work, especially on commercial lots and shared laneways.
Where the connection meets the city system
Your private drainage stops at the property line. From there, it ties into the municipal storm main. Utilities Kingston manages water, sewer, and storm service connections inside the city. So before any storm connection goes in, we confirm the location and depth of the municipal main with Utilities Kingston.
Outside city limits, the process differs by township. In Loyalist Township, South Frontenac, or elsewhere in rural Frontenac County, the connection may run to a ditch, a swale, or a rural storm system instead. We match the plan to your actual location.
Permits and inspections
Yes, you usually need a permit. A storm sewer connection ties into public infrastructure, so the municipality wants to inspect the work. Inside Kingston city limits, the permit and connection approval go through the City and Utilities Kingston.
For properties in the townships, the local building department handles it. That means South Frontenac, Central Frontenac, or Loyalist Township, depending on where you live. Just to be clear, KFL and A Public Health does not handle these permits. We sort out the right approvals as part of the job.
Inspections matter because they confirm the connection is done right. A bad connection can flood a neighbour or contaminate the storm system. So the inspection protects everyone, including you.
What the excavation involves
Connecting to a storm sewer means digging. The storm main sits well below the surface, often deeper than you would expect. So the trench can be several feet deep, and depth affects both cost and safety.
Here is the general order of work.
- Locate everything. We book utility locates before any dig, because hitting a gas or hydro line is dangerous and expensive.
- Plan the route. We map the shortest safe path from your drainage to the storm main.
- Excavate the trench. We dig down to the connection point and shore the walls where needed.
- Make the connection. We tie the new pipe into the municipal storm main and set the grade so water flows the right way.
- Inspect and backfill. After the inspection passes, we backfill, compact, and restore the surface.
Trench safety is a big part of this. Deep trenches can collapse without proper shoring, so we follow the trenching and shoring standards from the Infrastructure Health and Safety Association. That keeps our crew safe and your project on schedule.
Restoring your property afterward
Excavation disturbs the yard, so we plan the cleanup from the start. We compact the backfill in layers to prevent settling. Then we restore the surface, whether that means topsoil and seed, gravel, or new asphalt.
Since we grade the finished surface to shed water, the drainage keeps working long after we leave. Good grading is half the job.
Cost considerations for a storm connection
Every property is different, so we do not quote a flat price. However, a few factors drive the cost up or down.
- Trench depth and length: deeper and longer runs take more time and equipment.
- Surface type: cutting through asphalt or concrete adds restoration cost.
- Number of catch basins: more drains mean more pipe and more connections.
- Permit and inspection fees: these vary by municipality.
- Utility conflicts: gas, hydro, or water lines in the path add care and time.
For an accurate number, we come out, look at your site, and give you a written quote. That way you know exactly what the job costs before we start. No surprises.
A quick worked example
Say you have a bungalow with two downspouts flooding a low spot beside the driveway. We would add a catch basin in the low spot, run pipe to the property line, and tie into the storm main. Then we would connect both downspouts to the same system.
Since the trench is short and the surface is mostly lawn, this sits at the simpler end of the scale. A commercial lot with several catch basins and an asphalt driveway would cost considerably more. So the range is wide, and a site visit is the only honest way to price it.
Common problems we fix
Over 20 years we have seen the same drainage issues again and again. Here are the ones that bring homeowners to us.
- Disconnected downspouts dumping roof water at the foundation.
- Old clay pipe that has cracked or filled with roots.
- Storm water piped into the sanitary sewer by mistake, which is not allowed.
- Blocked catch basins that overflow in heavy rain.
- Poor grading that sends water toward the house instead of away.
Because these problems overlap, we look at the whole property before we recommend a fix. Sometimes a full storm connection is the answer. Other times, better grading and a new downspout run solve it for far less.

Frequently asked questions
Do I need a permit for a storm sewer connection in Kingston?
Yes, in most cases. A storm sewer connection ties into public infrastructure, so the municipality requires a permit and an inspection. Inside city limits, that goes through the City and Utilities Kingston. In the townships, the local building department handles it. We arrange the right approvals for you.
Can I connect my downspouts to the sanitary sewer instead?
No. Storm water and sanitary wastewater must stay separate. Piping roof water into the sanitary sewer overloads the system and can cause backups. So downspouts and foundation drains connect only to a storm system or an approved discharge point.
How deep is the trench for a storm connection?
It depends on the depth of the municipal storm main, which is often several feet down. Deeper trenches need proper shoring for safety. We confirm the main’s depth before we dig, then plan the trench around it.
What is the difference between a catch basin and a storm sewer?
A catch basin is the surface drain that collects water through a grate. The storm sewer is the pipe network that carries that water away. The catch basin ties into the storm sewer, so they work together as one system.
How long does a storm connection take?
A simple residential connection often takes a day or two, plus time for permits and the inspection. Larger sites with several catch basins take longer. We give you a realistic timeline with your quote.
