Private drainage tie-in
A trench drain tied into existing private storm, a 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 Ajax
Driveway and garage drainage across Ajax, from the historic Pickering Village core to the newer subdivisions north of Taunton.
What we install
Trench drain work across Ajax
Ajax spans a wide age range of construction. Pickering Village properties come with older private drainage that has to be verified before anything ties into it; the newer north end usually has a clean modern outlet.
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 Ajax homeowners say
Older street, older pipe. They camera-checked the existing line before promising it could take the drain. It could not, and they said so.
Ajax-specific
TRCA regulation, Durham Region servicing, and older private drainage
Ajax drains through Duffins Creek and Carruthers Creek, both inside TRCA jurisdiction. The other Ajax-specific issue is age: in the older core, the existing private line is often the limiting factor rather than the permit.
Older private drainage in Pickering Village
In the older parts of Ajax the existing private storm line may be clay, undersized, partially collapsed, or root-intruded. Tying a new drain into a failing line moves the problem rather than solving it. We verify the line before we design around it.
Duffins Creek and Carruthers Creek
Properties near either creek or their valley lands sit inside TRCA regulated area, which reviews excavation and drainage changes ahead of the Town.
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 it, and we do not install a connection that would conflict with the applicable by-law.
Coverage
Response from our Richmond Hill base
Ajax runs roughly 50 to 70 minutes from Richmond Hill depending on the 401 and the 407. We group Ajax site visits with other Durham work and book them in fixed windows.
The crew that quotes the job is the crew that installs it. Most residential jobs are a single day on site, with the patch curing 24 to 48 hours before vehicles go back on it.
- Drive time from HQ 50–70 min
- Quote window Fixed slot

FAQ
Common questions about trench drains in Ajax
Do I need a permit for a trench drain in Ajax?
Usually not for the drain itself when the outlet is existing private drainage on your lot. A new municipal storm connection needs a permit, and TRCA approval applies if your property sits inside their regulated area near Duffins or Carruthers Creek. Both are confirmed on the site visit.
My house is in Pickering Village and the drainage is original. Is that a problem?
It is the thing worth checking before anything else. Original clay lines in the older Ajax core are frequently root-intruded or partially collapsed, and a new trench drain feeding into a failing line just relocates the failure. We verify the existing line first and tell you what it can actually carry.
What does an Ajax trench drain cost?
Residential installs land in the GTA-wide $1,800 to $4,500 range. Ajax jobs move up when the existing outlet turns out to need replacement, which is a real possibility in the older parts of town and one we would rather flag before you commit than discover on install day.
Water pools at the bottom of my driveway every spring. Is a drain the fix?
Usually yes, if there is somewhere legal for the water to go. A trench drain across the low point intercepts it before it reaches the garage. The design work is in the outlet, not the channel — that is the part that decides whether the drain works in a heavy storm or just in a light one.
Do you work on Ajax commercial properties?
Yes. Plaza loading areas, service bays, restaurant washdown drainage, and industrial floors are quoted after a site visit. Traffic load and discharge routing vary too much between sites to price from a template.
How long is the job disruptive for?
One day on site for most residential installs. Saw-cutting is loud for a couple of hours. Vehicle access across the patch is off for 24 to 48 hours afterward, and we agree where you will park before we start.
Can you tie a trench drain into my sump discharge?
Sometimes, and it depends on capacity. A sump pump sized for groundwater may not handle a driveway’s worth of storm runoff on top of its normal load. We check what the existing pump and line can carry before designing the drain into it.
Do you coordinate with landscapers on Ajax hardscape projects?
Regularly. Setting the channel to the landscaper’s finished elevation before the interlock goes down produces a flush grate and costs far less than retrofitting into finished hardscape later.
