Installation of a New Commercial Septic System - 4420 Hunt Club Road West - Ottawa, ON

4420 West Hunt Club is a heritage farmstead within the National Capital Commission's (NCC's) commercial real estate portfolio. Today, the property is home to a banquet hall and barn, which have served as an event facility for decades, connecting thousands of visitors with the region's agricultural heritage. the Banquet Hall at 4420 West Hunt Club Road was built in 1970. It is a wood framed building with metal cladding on the exterior, sitting on a concrete slab foundation. For the first thirty years, it was used as a machine shed but around 2001, it underwent major renovations to make it suitable for corporate events. The sanitary facilities for the building are housed in a portable washroom unit with self-contained plumbing, located immediately east of the building.

At present, the property needs upgrades to directly improve the overall leasing and revenue potential of the asset. The upgrades will also contribute to the preservation of agricultural heritage in Canada's Capital, contribute to this farm's long history of agri-tourism and improve its function as a functional space and sustainable farmstead.

One such upgrade to the property includes the installation of a commercial septic system. The commercial septic system will primarily serve the banquet hall.  This project involves the installation of larger tanks and leaching fields. The leaching fields will be located in an area currently covered in brush, just west of the banquet hall, and will occupy approximately 2,000m2.

The NCC will require to make a determination under the Impact Assessment Act. Additionally, the installation of the septic system needs to be in accordance with local regulations and by-laws.
