A P3 Success: City of Greater Sudbury Biosolids Management Facility

Sudbury Biosolids Management FacilityOn Thursday May 7th, the City of Greater Sudbury announced that their new state-of-the-art, award-winning Biosolids Management Facility was operational. This facility is the first of its kind in northern Ontario and establishes Greater Sudbury as a leader in environmentally sound water/wastewater processing.

The Biosolids Management Facility is a centralized wastewater sludge dewatering and stabilization facility producing Class A biosolids at the Sudbury Wastewater treatment plant. The facility will respond to the current restraints placed on the City’s disposal practices as an environmentally responsible and sustainable plant that is safe to all surrounding communities, delivering a long- term, modern approach to wastewater management.

The City-owned facility, and public-private partnership (P3) Biosolids Management Facility, is operated by
N-Viro®, a Walker Environmental Company.

“In implementing the P3 model, we are able to realize a number of benefits such as leveraging the experience of the private sector in operating this facility and distributing the end product,” said Tony Cecutti, General Manager of Infrastructure Services for the City of Greater Sudbury. “Utilizing the expertise of N-Viro allows us the opportunity to reduce operational costs and keep in line with industry best standards.”

The project has been in progress since 2007 and was initiated to improve sludge disposal practices in Greater Sudbury. In 2012, the City entered into an agreement with N-Viro Systems Canada LP, now part of the Walker Environmental , for the Design, Build, Finance, Operation and Maintenance (DBFOM) of a City-owned biosolids management facility, with N-Viro committing to a financing plan over the full 20-year term of the contract. As part of the agreement, the City will also receive revenue from sales of the biosolids end-product.

“Walker Environmental is very proud to be investing in the City of Greater Sudbury’s Biosolids initiative,” said Mike Watt, Executive Vice-President, Walker Environmental Inc. “We successfully process and produce fertilizer in five other locations across Canada. Our process turns organic residuals into an agricultural and beneficial soil amendment called N-Rich®, used primarily in the agricultural sector and for land reclamation projects.”

“This project is another great example of how public-private partnerships bring together important public infrastructure initiatives and the expertise of the private sector,” said John McBride, CEO PPP Canada. “The City of Greater Sudbury demonstrated a clear need for this project. Public infrastructure projects such as water treatment facilities improve public health and enhance the quality of life of all Canadian families.”
