Hartland Resource Management Group (HRMG) has been named Preferred Proponent for the Capital Regional District (CRD) Residuals Treatment Facility.
The project will be delivered under a design-build-finance-operate-manintain (DBFOM) Public-Private Partnership (P3) model, with a 20-year operate and maintain period. The facility will incorporate the latest processes for stabilizing and drying biosolids. The CRD conducted an evaluation process to select the proponent for what will be their final step in attaining advanced wastewater treatment.
HRMG is a special purpose company of which Maple Reinders PPP Ltd. is a partner along with Bird Construction Inc. and Synagro Capital. “Maple Reinders has been following the development of the CRD’s wastewater treatment strategy and is particularly enthused with this opportunity to play a role in its further realization”, said Maple Reinders’ director of infrastructure development, Reuben Scholtens.
Residual solids from the McLoughlin Point Wastewater Treatment Plant will be piped to the Residuals Treatment Facility at Hartland Landfill, where they will be treated and turned into what are known as Class A biosolids. The biosolids will be a high-quality by-product safe for beneficial reuse.
“We are Canada’s most experienced water/wastewater contractor, and the CRD Residuals Treatment Facility represents a major achievement for us and is our fourth environmental DBFOM P3 project in as many years. As the established national leader in this space, we will continue to focus on bringing value to municipalities through the shared risk approach enabled by the alternative project delivery model,” said Scholtens.
The Residuals Treatment Facility will use an anaerobic digestion process followed by a dryer process to produce the dried, Class A biosolid. The dryer will be fueled by biogas generated during the digestion process. The dried product will look similar to a dark ash and will be suitable for several beneficial reuses, including as an alternative energy source. The ultimate use of these biosolids will be determined by a separate planning process which is being considered by the Integrated Resource Management Advisory Committee of the CRD Board.
The Residuals Treatment Facility is part of the CRD’s larger Wastewater Treatment Project, being built to meet both the federal and provincial governments’ December 31st, 2020 requirement for secondary wastewater treatment. HRMG plans to start construction in the spring of 2018, with the project slated for completion at the end of 2020.
