Underground Stormwater Systems are buried detention and infiltration systems that store and manage runoff beneath a site. In Georgina, Harrowgate Group takes on underground stormwater systems end to end: the site is surveyed and scoped, the work is built and managed on site, and the project is completed to the engineered plan.
Most Georgina underground stormwater systems jobs involve sites with limited surface space. Across Georgina, they solve managing stormwater underground where surface space is tight, and because no two sites are identical the scope is set per site, not a default.
Georgina's need for underground stormwater systems (York Region) is driven largely by municipal and recreational infrastructure, light industrial, tourism and waterfront commercial, and agricultural service. Georgina's Keswick corridor and Lake Simcoe waterfront drive municipal, commercial, and light-industrial construction with a seasonal and shoreline dimension. Demand spans municipal works, servicing, stormwater, and waterfront site work.
Most of it sits around Keswick and Sutton commercial areas, the Woodbine corridor, and the Lake Simcoe waterfront. Much of the Georgina work is for the Town of Georgina, developers, and local business, each needing the job built to the drawings, to code, and documented.
