Oil-Grit Separators are underground treatment devices installed to remove sediment, oil, and debris from stormwater runoff. Every oil-grit separators project Harrowgate Group takes on in Ottawa is scoped to one site, the ground, the loads, and the constraints assessed first, then the work completed to grade.
Ottawa oil-grit separators work centres on commercial sites, lots, and municipal drainage. Treating stormwater to meet water quality requirements are the recurring drivers; each Ottawa project is sized to its own situation, not a one-size approach.
What drives oil-grit separators in Ottawa (City of Ottawa) is government and institutional, technology and commercial, healthcare, and infrastructure and transit. Ottawa's federal government, technology sector, and transit expansion anchor one of Ontario's largest institutional and civil construction markets. Work spans government and institutional site development, transit civil, servicing, and concrete.
The work concentrates around the downtown government core, the Kanata technology park, the industrial and business parks, and the LRT corridors. Harrowgate Group regularly builds oil-grit separators for Ottawa clients like the federal government, tech firms, hospitals, and the City of Ottawa, each project carrying its own site and requirements.
From government and institutional, technology and commercial, healthcare, and infrastructure and transit, no two Ottawa oil-grit separators jobs are quite alike. Harrowgate Group matches scope, equipment, and crew to the specific property each time.
What shapes an Ottawa project is government and security site standards, LRT and transit infrastructure, and cold-climate frost design. So Harrowgate Group matches the methods, materials, and equipment to the site, and an Ottawa project rarely needs the same approach as a standard property.
