Stormwater Management and Drainage is the grading, structures, and systems that control and convey site runoff to code. Harrowgate Group builds stormwater management and drainage across Ottawa to the engineered drawings and the applicable codes, surveyed, built on site, and completed to grade for the real conditions.
In Ottawa, stormwater management and drainage is typically needed for developments, commercial sites, and municipal works. Controlling site runoff and meeting stormwater requirements are the recurring drivers; each Ottawa project is sized to its own situation, not a one-size approach.
What drives stormwater management and drainage 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.
Most of it sits around the downtown government core, the Kanata technology park, the industrial and business parks, and the LRT corridors. Clients such as the federal government, tech firms, hospitals, and the City of Ottawa drive much of the Ottawa work, and no two projects carry the same scope or ground.
Because Ottawa spans government and institutional, technology and commercial, healthcare, and infrastructure and transit, stormwater management and drainage is never one-size: Harrowgate Group fits the method to the building type, age, and use on every project.
In Ottawa, the work has to account for government and security site standards, LRT and transit infrastructure, and cold-climate frost design. Harrowgate Group sets the methods, materials, and equipment for those exact conditions on every Ottawa project, working to the site conditions and the engineered drawings rather than a regional default.
In Ottawa, Harrowgate Group treats schedule as part of the scope: fast mobilization, the right equipment on site, and the project built in the right sequence so the following trades are not held up.
An Ottawa stormwater management and drainage project moves through survey, site prep, the built work, and restoration, each step verified against the engineered plan and the applicable codes before the crew moves on.
