Biosolids-new-headerNiagara Region, Ontario

The Niagara Region facility has been in continuous operation since February 2007. Niagara Region operates several wastewater treatment plants, all having conventional treatment with digesters. Presently, the Region’s biosolids are dewatered by centrifuges at two dewatering facilities. The dewatered cake is trucked to the Niagara Region facility for processing. This facility was designed with excess capacity and also services other municipalities.

This project received a P3 award from the Canadian Council for Public and Private Partnership in 2006. In 2014, it also received the Exemplary Biosolids Management Award from the Water Environment Association of Ontario.

Walker Environmental owns and operates this facility.


The Niagara Region facility is located on the Walker Industries campus, which straddles the border of Niagara Falls and Thorold, Ontario. The plant serves a population of approximately 430,000.


Approximately 35,000 tonnes of Niagara N‐Rich® is produced per year.
