City of Powell River Turn-Key Biosolids Management

Client: 
City of Powell River

The City of Powell River operates the Westview Wastewater Treatment Plant which produces approximately 1,300 wet tonnes of Class B dewatered biosolids per year. SYLVIS has partnered with the City for more than a decade to beneficially manage biosolids produced at this facility in mine reclamation and agricultural fertilization. Between 2003 and 2016 City biosolids were managed at the Lehigh Hanson Materials Sechelt sand and gravel mine in an award-winning reclamation program. Biosolids application and storage at the mine occurs under a permit issued by the Ministry of Environment. This award-winning program was initiated in 1998 and is one of the most comprehensive mine reclamation programs in British Columbia (BC). Powell River biosolids are used in mine reclamation where biosolids are applied to mine soils lacking plant essential nutrients and organic matter required to sustain plant growth and improve soil properties.

The Lehigh Sechelt Mine reclamation program is one of the longest standing biosolids mine reclamation programs in BC and has been recognized with five awards including the prestigious Jake McDonald Reclamation Award from the Technical and Research Committee on Reclamation for outstanding achievement in reclamation and is an excellent biosolids management option for the City of Powell River.

Since 2017, City biosolids have been managed at a farm on Vancouver Island. Biosolids are applied to remote fields where the farmer has previously not applied manure due to the expense of manure transport. Soils at the land application site are low in organic matter and have low to moderate levels of other plant nutrients. City biosolids, managed together with chemical fertilizer in a comprehensive nutrient management approach, will provide nitrogen, phosphorus, and a host of micronutrients to the forage crop.
