What are biosolids?

Biosolids Management
Thomas Nutrient Solutions NASM Management
Biosolids are a nutrient rich, organic by-product of wastewater treatment. The Niagara Region owns and operates wastewater and water treatment facilities that treat and clean the wastewater from Niagara Region’s residents and businesses.

The biosolids generated from this treatment process then are recycled as agricultural fertilizers and help to maintain and improve soil productivity and stimulate plant growth. This is then applied to agricultural land only after the material is fully treated and meets strict quality standards set by the Ontario Ministry of Environment. Any pathogens in the wastewater are eliminated through a treatment process and the pathogens that are left are further reduced when exposed to the natural elements, both during storage and when applied at the farmer’s field.

When conditions permit, nutrients are directly applied to agricultural land between the months of April and November. The program is closely monitored and when the nutrients cannot be applied, such as periods of wet weather or during the winter months, temporary storage is required.

At Niagara Region’s Garner Road location, the biosolids are delivered and treated to become the nutrient rich, organic fertilizer that is applied to the crops within the Region.
