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’emlúps te Secwépemc through an existing sewer agreement.
Following 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 City has worked with Stantec Consulting Ltd. to develop its strategy for an updated biosolids management plan. The City also formed a Biosolids Management Stakeholder Committee to seek feedback and input from a variety of stakeholders on a long-term strategy for the management and beneficial reuse of biosolids produced at the KSTC. The committee included representation from the following organizations:
- Thompson-Nicola Regional District
- Tk’emlúps te Secwépemc
- First Nations Health Authority
- Kamloops Stockmen’s Association
- Fraser Basin Council
- City Council
- City of Kamloops staff
The methodology and process for developing the biosolids strategy has been comprehensive. It involved collecting data; establishing decision-making frameworks; evaluating technologies from around the world; and applying analyses that take into consideration the environment, economy and social implications. The process is outlined below.
The final recommended biosolids management options were presented to City Council in the Summer 2019 and will help guide future decision making.
