Private drainage tie-in
Tying into your existing private storm line, sump discharge, or a soakaway on your own lot has its permit scope determined by the Town under its by-laws. We confirm what applies before work begins.

Trench Drain Installation in Whitby
Driveway, garage, and commercial trench drains across Whitby — from the Port Whitby lakeshore up to Brooklin.
What we install
Trench drain work across Whitby
Whitby is a two-part market: established central neighbourhoods with mature trees and older private drainage, and the fast-growing Brooklin end where the storm system is new but the lot grading is tight.
Install Process
How a trench drain goes in
Six on-site steps from the first cut to a flush, water-tight finish. Same sequence on every job — what changes is length, materials, and crew size.
-
01
Plan & Mark
- Identify water flow direction
- Mark full drain run across the opening
- Confirm outlet location and slope (~1%)
-
02
Excavate Trench
- Cut and remove concrete or asphalt
- Trench wider and deeper than the channel
- Maintain consistent slope toward the outlet
-
03
Prepare Base
- Add compacted gravel or concrete base
- Set elevation using string line or laser
- Base supports full channel length
-
04
Install Channel
- Place channel sections across full trench
- Connect end-to-end with no gaps
- Align slope and elevation across the run
-
05
Concrete & Backfill
- Pour concrete around both sides of channel
- Maintain proper thickness and support
- Finish surface flush with surrounding slab
-
06
Grate & Finish
- Secure the grate into the channel
- Ensure flush finish with the slab
- Final check: water flows cleanly into drain
Customer review
What Whitby homeowners say
They set the channel to the exact elevation our landscaper was working to. The grate sits dead flush. No lip, no trip hazard.
Whitby-specific
CLOCA regulation, Durham Region servicing, and Brooklin subdivision grading
Whitby sits inside Central Lake Ontario Conservation Authority territory rather than TRCA. Lynde Creek and Pringle Creek and their valley lands are the regulated areas that most often affect residential drainage work here.
Lynde Creek, Pringle Creek, and valley lands
Properties inside CLOCA’s regulated area need their review of excavation and site alteration before the Town will act. We check your address against the mapping at the site visit.
Newer Brooklin lot grading
Brooklin’s newer subdivisions have registered grading plans and inter-lot swales. A drain that changes where water leaves your lot can put you offside the approved plan or into a dispute with a neighbour. We design within it.
Sanitary sewer discharge
The Region of Durham sewer use by-law governs what may enter the sanitary sewer, and surface water is restricted under it. We do not install a connection that would conflict with the applicable by-law.
Coverage
Response from our Richmond Hill base
Whitby is roughly 55 to 75 minutes from Richmond Hill via the 407. We group Whitby site visits with other Durham work and book them in fixed windows rather than leaving you a four-hour gap.
The crew that quotes the job installs it. Most residential Whitby installs are one day on site, followed by 24 to 48 hours of cure before vehicle traffic.
- Drive time from HQ 55–75 min
- Quote window Fixed slot
- Typical residential install 1 day on site

FAQ
Common questions about trench drains in Whitby
Do I need a permit for a trench drain in Whitby?
Usually not for the drain itself when we tie into existing private drainage. CLOCA review applies if the property sits inside their regulated area near Lynde or Pringle Creek, and a new municipal storm connection needs a permit. We confirm both on the site visit.
Which conservation authority covers Whitby?
Central Lake Ontario Conservation Authority, CLOCA — not TRCA. Watershed boundaries do not follow municipal lines, so Whitby, Oshawa, and Clarington sit with CLOCA while Pickering and Ajax sit with TRCA. It changes who reviews the work and how long approval takes.
I am in a new Brooklin build and water sits against the garage. Whose problem is it?
Lot grading performance can fall within the scope of a new-home warranty. Lot grading that does not perform can be the builder’s obligation while the home is still in its warranty period. We will tell you at the site visit if that looks like your situation, even though it means we do not get the work.
What does a Whitby trench drain cost?
Residential installs sit in the $1,800 to $4,500 GTA range. Whitby jobs stay in the lower half when there is a clean modern outlet, and move up when the run is long, the apron is wide, or the outlet needs real plumbing work.
Can you do the work around a finished hardscape?
Yes, though it costs more than doing it during the build. Interlock lifts and relays cleanly. Poured concrete and stamped finishes have to be saw-cut and patched, and the patch will always be visible to some degree. We are upfront about that before you decide.
Do you handle Whitby commercial and industrial work?
Yes — loading docks, service bays, plaza aprons, and warehouse floors across the Whitby employment lands. All quoted after a site visit, since load class and discharge routing drive the specification.
What is the maintenance like afterward?
Lift the grate and clear the channel twice a year, spring and late autumn, plus once after heavy leaf fall if you are under mature trees. That is the whole routine. A neglected channel silts up and stops working long before the drain itself fails.
Do you install in winter in Whitby?
Yes, with real limits. Frozen ground slows excavation and concrete needs protection below certain temperatures. We work to the forecast and will tell you when waiting for spring gives you a better result.
