Reclamation of Bob’s Lake Pit

Regional District of Central Okanagan

The Regional District of Central Okanagan contacted SYLVIS Environmental to undertake an assessment of short and long term biosolids management options.  Several potential biosolids land application opportunities resulted, including land application of biosolids for reclamation at Bob’s Lake Pit.

Bob’s Lake Pit was a source of aggregate for the construction of Highway 97C in the early 2000’s.  Prior to the reclamation project, the 30 hectare area had little to no soil present with extremely low nutrient and organic matter concentrations, which inhibited vegetative growth.

Regional District of Central Okanagan biosolids were applied and incorporated to the site.  Several pieces of equipment were utilized to facilitate an even application rate and thorough incorporation to both the sloped and more level sections of the pit.

The application of biosolids at Bob’s Lake Pit has provided nutrients, organic matter and a stable growing medium for grasses in the short term and eventual succession of naturally occurring tree species in the area as the soil develops.

SYLVIS continues to work with the Regional District of Central Okanagan to develop other biosolids management opportunities throughout the region.
