Discharge route first
Clean runoff goes to storm. Wash water needs an interceptor. Process effluent may need pretreatment and a discharge agreement under the municipal sewer use by-law. Nothing is designed until this is established.
Commercial & Institutional
Commercial trench drain installation across the GTA
Licensed since 1991, working on sites that cannot stop. We establish the discharge route and the load class before we price anything, and we phase the work so you keep operating.
What makes commercial work different
A residential trench drain has one job: move surface water to a legal outlet. A commercial drain has to do that while surviving the traffic that crosses it, satisfying whatever governs the water it carries, and going in without shutting the business down.
Those three constraints — load, discharge, and continuity — decide almost everything about the specification and the price. We settle them at the site visit, before quoting, which is why we do not price commercial work over the phone.
Load class from actual traffic
Not from the building type. Forklifts punish a drain harder than trucks do, and a grate rated for the wrong thing fails within a season. Delivery lanes, dock aprons and production aisles each get specified for what really crosses them.
Installed around your operation
Bay by bay at a dealership, zone by zone in a plant, off-hours next to patient care. Phasing is planned with your team before the first cut, and the cure window is built into the schedule rather than discovered.
Fixed, itemised quotes
You see what is drainage, what is compliance, and what is access. After-hours premiums and interceptor work are named lines, not margin folded into a lump sum.
Commercial & institutional property types
Every commercial property type we install trench drains for. Each page covers the load class, the discharge route, and how the install is phased around your operation.

See detailsWhat a commercial job costs
Commercial work is quoted after a site visit, and for a reason we explain in full on the commercial cost guide: load class, discharge requirements, and after-hours phasing move the number far more than the channel does.

Master Plumber licensed, operating across the GTA as the trench drain practice of MT Drains & Plumbing Ltd. since 1991. We work directly with facilities teams and to mechanical consultants’ specifications through general contractors.
Commercial questions
Do you work directly with facilities teams or through the GC?
Both. On construction and renovation projects we work through the general contractor and to the mechanical consultant’s specification, providing shop drawings for review. For direct facility work we deal with your maintenance or operations lead. Either way the discharge route and phasing get confirmed in writing before we start.
Can you install without shutting our operation down?
In almost every case, yes — that is the normal way we run commercial work. Dealerships come out bay by bay, plants zone by zone, healthcare areas on an agreed continuity plan and usually off-hours. Some scopes, like a car wash conveyor tunnel, genuinely need a planned shutdown, and we tell you that up front rather than discovering it.
How quickly can you get out for a commercial site visit?
Usually within the same week across the GTA, in a fixed time slot. We do not quote commercial work without seeing it, because the discharge route and the real traffic loading cannot be established from a description.
Do you handle the permits and approvals?
Yes. Where a job needs a municipal storm connection permit, an interceptor, or coordination on a sewer discharge position, we handle the application and inspection coordination. On healthcare sites we work to your infection control process. We identify what applies at the site visit so the timeline is honest from the start.
What if our current drainage is not compliant?
We will tell you, and we will not tie new work into a non-compliant discharge. Process or wash water reaching the storm system is the most common version of this. It changes the right scope of work, and finding out during a quote is a great deal better than finding out from an inspector.
Do you service what you install?
Yes, and we hand over the maintenance routine at completion. Commercial installations need clearing far more often than residential ones — quarterly on high-traffic and washdown sites, and interceptors on their own service interval. A drain that is not maintained silts up and stops working long before it wears out.
