The Leamington facility was the first Canadian N-Viro® facility and has operated continuously since January 1996. The biosolids (produced at the Pollution Control Centre) are dewatered through centrifuges to 22-25% total solids prior to processing through the N-Viro® facility.

The municipality owns and operates the facility and Walker Environmental provides technical and marketing support under a long-term contract.
