Oil-Grit Separators are underground treatment devices installed to remove sediment, oil, and debris from stormwater runoff. Harrowgate Group builds oil-grit separators across Etobicoke to the engineered drawings and the applicable codes, surveyed, built on site, and completed to grade for the real conditions.
Most Etobicoke oil-grit separators jobs involve commercial sites, lots, and municipal drainage. Across Etobicoke, they solve treating stormwater to meet water quality requirements, and because no two sites are identical the scope is set per site, not a default.
Demand for oil-grit separators in Etobicoke (City of Toronto) comes mostly from industrial and manufacturing, logistics and distribution, commercial and office, and airport-area development. Etobicoke's airport employment zone and 427 corridor form one of the GTA's densest industrial and logistics markets. Demand centres on warehouse slabs, truck-court paving, servicing, and commercial site work near Pearson.
Most of it sits around the airport employment zone, the Queensway, Islington and Kipling business areas, and the 427 corridor. Harrowgate Group regularly builds oil-grit separators for Etobicoke clients like logistics operators, manufacturers, developers, and the City of Toronto, each project carrying its own site and requirements.
From industrial and manufacturing, logistics and distribution, commercial and office, and airport-area development, no two Etobicoke oil-grit separators jobs are quite alike. Harrowgate Group matches scope, equipment, and crew to the specific property each time.
The Etobicoke variables that matter are airport-area flight-path and servicing constraints, heavy truck loading on the 427 corridor, and large industrial slab and pavement scopes. Harrowgate Group sets the methods, materials, and equipment for those exact conditions on every Etobicoke project, working to the site conditions and the engineered drawings rather than a regional default.

Harrowgate Group coordinates with your structural and civil engineers, architects, city planners, geotechnical consultants, and the municipal reviewers whose sign-off the work needs, building to the stamped drawings, honouring the design intent, and keeping the Etobicoke project aligned with what was engineered and approved.
