A Drainage Contractor designs and installs site drainage, from storm sewers and catch basins to trench drains and stormwater systems, for commercial and municipal sites. Harrowgate Group treats each Whitby drainage contractor project as its own scope: the site conditions, the engineered plan, and the sequencing set before a crew mobilizes.

Demand for drainage contractor in Whitby (Durham Region) comes mostly from logistics and distribution, advanced manufacturing, commercial and institutional, and greenfield industrial. Whitby's industrial park and 407 employment lands are absorbing major logistics and manufacturing development, with Brooklin growing north. Work runs to greenfield servicing, mass grading, and large-format concrete and paving.
