Trenching Services in Etobicoke — Utility, Drainage, Pool Lines

OCM Excavation runs trenching across Etobicoke for water service upgrades, weeping tile and storm drainage, gas and electrical conduit, and pool feed lines. We work from Long Branch and Mimico on the lake up through Alderwood, The Kingsway, Markland Wood, Centennial Park and the Humber Bay corridor. Older West Toronto homes often need the 1/2-inch lead or galvanized line swapped for 3/4-inch or 1-inch copper, and we cut that trench cleanly without tearing apart your front yard.

Trenching Work We Do in Etobicoke

Etobicoke has a mix of post-war bungalows, infill custom builds, and lakefront properties that all generate different trenching needs. We size and route each trench to the utility, not the other way around.

• Water service upgrades — lead and galvanized replacement to 3/4-inch or 1-inch copper, from the curb stop to the basement entry. Common in older Long Branch, Mimico and Alderwood homes.
• Storm and weeping tile — perimeter drainage tied to a sump or storm connection, typically 4-foot to 6-foot deep along the foundation.
• Gas and electrical conduit — utility-spec trench depth for Enbridge and Toronto Hydro tie-ins on new builds, additions and garages.
• Pool feed and return lines — bonded conduit and PVC runs from the pad to the pool, plus auto-fill and gas to the heater.
• Downspout disconnection and rainwater leaders — required across Etobicoke under the City’s downspout disconnection rules; we trench the new discharge route.
• Sewer line trenching — full open-cut replacement when relining isn’t an option, including backwater valve installs.

How We Trench in Etobicoke

Every trenching job in Etobicoke starts with a public utility locate (Ontario One Call, ticket usually back in 5 business days). We layer in a private locate if the property has irrigation, low-voltage landscape lighting, or unmarked gas to a pool heater — common in The Kingsway and Markland Wood. Trenches under 1.2 m can run open; anything deeper gets shored or benched per Ontario Regulation 213/91. We use mini-excavators on tight lots — most Mimico and Long Branch frontages won’t take a full-size machine without lawn damage.

If the trench crosses the City road allowance or sidewalk — which it usually does on a water service upgrade — a Toronto road occupancy permit applies. We pull that on your behalf and coordinate the curb stop tie-in with Toronto Water.

Etobicoke Site Conditions That Affect the Trench

Etobicoke isn’t one soil. The lakefront strip from Humber Bay through Mimico down to Long Branch has high water tables and silty clay — trenches over 1.5 m often need pumping. Alderwood and Markland Wood sit on heavier clay; great for trench wall stability, harder to compact back. The Kingsway and Centennial Park have mixed fill from decades of regrading, so we hand-dig the last 300 mm near any service entry to avoid striking unmapped utilities. Mature tree canopy across most of Etobicoke means we route trenches outside the critical root zone wherever possible, and the City’s tree protection by-law (30 cm DBH threshold for private trees) is something we check before we cut.

What a Trenching Job Costs in Etobicoke

We don’t quote trenching by the linear foot sight-unseen — depth, soil, restoration, and permit scope all swing the number. As a working range, a residential water service trench from the curb to the house in Etobicoke typically runs 1 to 2 days of crew time. A perimeter weeping tile trench is usually 2 to 3 days. Pool line trenching is often half a day to a day. We give you a fixed written quote after a free site visit. The City of Toronto runs a Water Service Subsidy Program that reimburses eligible private-side lead replacements up to $6,650; we’ll flag whether your job qualifies.

Etobicoke Trenching FAQ

Do I need a permit to trench across the boulevard in Etobicoke?

Yes — any trench that crosses the City road allowance, sidewalk or curb in Etobicoke needs a Toronto road occupancy permit, and a water service tie-in needs Toronto Water coordination at the curb stop. We handle both as part of the job so you don’t get a stop-work order mid-dig.

How deep does a water service trench have to be in Etobicoke?

Toronto’s frost depth standard for water services is 1.5 m (about 5 feet) of cover. We typically trench to roughly 1.7 to 1.8 m to give the line bedding and a margin above the City main connection. Deeper runs near Humber Bay or Long Branch may need shoring if the water table is high.

Can you trench without tearing up my Etobicoke lawn?

For short, straight runs in soft soil we can sometimes use directional boring or moling. Most water service replacements in The Kingsway and Markland Wood still go open-cut because of the depth and the curb stop tie-in, but we strip sod in sections, stage spoil on boards, and re-lay it where possible.

Does the Toronto lead-pipe replacement subsidy apply in Etobicoke?

Yes. Etobicoke is part of the City of Toronto, so the Water Service Subsidy Program applies. As of 2026 the cap is $6,650 for the private-side portion of a lead service replacement. We’ll tell you on the site visit whether your home appears eligible and what paperwork the City needs.

How long does a typical trenching job take in Etobicoke?

A residential water service run is usually 1 to 2 days from breaking ground to restoration. Perimeter drainage and weeping tile is 2 to 3 days. Pool feed lines are often a half day to a day. Permit lead times can add a week or two before the dig date depending on the City’s queue.

Do you protect mature trees during trenching in Etobicoke?

We route around the critical root zone wherever possible and hand-dig near significant roots. Toronto’s private tree by-law protects trees 30 cm DBH and larger, and the City street tree by-law covers boulevard trees. If a protected tree is in the trench line we’ll flag it and discuss alternate routing before we cut.
