Biosolids Management

The City of Kamloops and its residents produce an average of 12,500 bulk tonnes of biosolids every year through the treatment process at the Kamloops Sewage Treatment Centre (KSTC). This includes sewage treated from the Tk’emlups te Secwepemc through an existing sewer agreement.

Following the construction upgrades at KSTC, the improved treatment process resulted in more biosolids being produced. Biosolids were stockpiled on site at KSTC while a management plan was being developed. The stockpile of biosolids is approximately 23,000 tonnes and has reached capacity.

The City of Kamloops is addressing the immediate need for short-term biosolids management options while seeking potential long-term alternatives to traditional biosolids management techniques.

  • City of Kamloops Short Term Solution for Biosolids

    about 1 month ago

    In the short term, to manage accumulated biosolids in Kamloops while a long-term solution is decided, the City has entered into a contract with Arrow Transportation Systems Inc. (Arrow). Arrow and NutriGrow, a soil solutions company in Arrow’s Environmental division, will fulfill the contract in partnership with the Little Shuswap Lake Indian Band (LSLIB).

    Arrow and NutriGrow are proven market leaders in biosolids management, with a fleet of specialized vehicles designed for the safe transportation of biosolids. Over the next two years, Arrow will haul the City’s daily production of biosolids and approximately 23,000 tonnes of stockpiled biosolids to...

    Arrow and NutriGrow are proven market leaders in biosolids management, with a fleet of specialized vehicles designed for the safe transportation of biosolids. Over the next two years, Arrow will haul the City’s daily production of biosolids and approximately 23,000 tonnes of stockpiled biosolids to a composting and soil fabrication facility located on LSLIB lands.

    The facility will be managed by NutriGrow according to stringent environmental and regulatory standards, and it will be monitored by independent, third-party qualified professionals. The facility will produce a high-quality, nutrient-rich compost which can then be blended into soil. The LSLIB will use this soil to construct a nine-hole expansion of the Talking Rock Golf Course.

    Prior to selecting the site for the compost facility, NutriGrow and Arrow evaluated several different options. After extensive research and consideration, they selected the partnership with LSLIB because it offered the best fit and potential outcomes to all stakeholders, including the City of Kamloops and its citizens.

    The City of Kamloops Biosolids Stakeholder Management Committee continues to investigate options globally for a long-term biosolids management solution.

  • Summary of Biosolids Committee Meeting - September 12, 2018

    about 1 month ago

    The committee further reviewed the revised triple bottom line analysis and how it applies to long-term technology options in Kamloops. The technologies being reviewed under the triple bottom line analysis include:

    • In-vessel/enclosed composting with amendments
    • Land application
    • High rate biomass production
    • Liquid fertilizer production - liquification
    • Thermal drying and sale for hog fuel
    • Thermolysis - pyrolysis

    An overview of these technologies is available for viewing here.

    The progress thus far is currently being summarized and will be presented to Council on September 25.

    about 1 month ago

    The committee provided feedback on the options reviewed at the July 9 meeting. The group also looked in greater detail at regulations being used in the European Union and how to apply them to the evaluation criteria. The group was presented with opportunities for quality improvement and biosolids reduction. The next steps involve determining a process for gathering public feedback and reporting the progress to Council.
