Long Term Biosolids Strategy

Client: 
Regional District of Central Okanagan

The Regional District of Central Okanagan (RDCO) contracted SYLVIS to undertake an assessment of short and long term biosolids management options.  The goal of the project was to identify management opportunities that will provide the RDCO with diversified options that can be applied over the long term and that reflect the RDCO’s commitment to promoting public health, environmental sustainability, flexibility and cost effectiveness.

To identify and assess the options available for biosolids management SYLVIS initially conducted a review of all background reports and data provided by the RDCO, collected and analyzed RDCO biosolids and initiated correspondence with potential project partners.

Potential opportunities were assessed based on a variety of considerations: environmental, social, economic, technical and market potential.

Recommendations were made based on these considerations and the potential for each opportunity to provide diversity and contingency to RDCO’s biosolids management program.  Areas identified by SYLVIS as potential opportunities include forest fertilization and biomass production, reclamation of degraded land (specifically decommissioned aggregate pits), production of value added products (such as Class A compost), and agricultural fertilization.  It is important over the long-term to develop a combination of feasible options so that the biosolids management program is diversified and thus flexible to accommodate changes and future uncertainties.

SYLVIS will continue to work with the RDCO to determine the most advantageous option based on the District’s ideals and needs.
