The City of Greater Sudbury has officially begun construction on a new biosolids management facility, which has been in the works for several years and is the City’s first Public-Private Partnership (P3).
During a joint announcement held on December 12, 2011, with the City of Greater Sudbury, Tony Clement, President of the Treasury Board and Minister for the Federal Economic Development Initiative for Northern Ontario, announced that the Government of Canada would contribute up to $11 million through the P3 Canada Fund to support the new biosolids management facility project. The remainder of the project’s construction costs will be financed by the City of Greater Sudbury and N-Viro, the Canadian-owned private consortium selected to design, build, finance, operate and maintain the facility. Ownership of the facility remains entirely with the City.
The City of Greater Sudbury has been using tailings ponds near Lively for over 30 years as a disposal site for waste activated sludge from its wastewater treatment facilities. While this was once an acceptable practice, changing environmental standards and recurrent episodes of foul odour have made this disposal method unsustainable. The City is required to cease using the tailings ponds for disposal purposes.
While a number of alternative project procurement methods were available to the City, it was determined that a DBFOM model offered the highest value for money. N-Viro’s submission offers value for money of approximately $11 million over the 20-year contract term. The lump sum construction price of N-Viro’s submission is $63.1 million. The deal between the City and N-Viro was finalized earlier in June, and N-Viro began mobilizing equipment on June 17, 2013. Construction is scheduled to be completed 24 months from now, in summer 2015.
Site mobilization for the construction of the CGS Biosolids Management Facility began June 17, 2013. It will take two years to build the plant and related infrastructure. The facility is designed to handle up to 15,000 wet tonnes of dewatered biosolids per year produced by the CGS.
The process is an entirely closed system designed to protect the environment inside and out by preventing the escape of air, dust and odours. The facility will operate throughout the year producing approximately 30,000 tonnes of their product, called N-Rich, annually.
As part of the P3 agreement with CGS, N-Viro is responsible for finding end users for the final product and for transporting it off site. The majority of the N-Rich to be produced at the CGS Biosolids Management Facility has been pre-sold for the next 10 years and will be used in mining reclamation projects in the Sudbury area. The balance will be sold for value to local agriculture users. N-Viro is also exploring the production of a special soil blend incorporating N-Rich. This soil blend will be sold to the retail market in the area.
