ONDEO HAS REACHED AN AGREEMENT to design, build and operate three WwTPs and to design and build a sewage collection system to treat wastewater from the 380,000 residents of Halifax, Nova Scotia.

Under the terms of the DBO agreement, Ondeo will operate and maintain the plants for a 30-year period. The total net present value (npv) of the project is Can$465 million (US$300 million) including capital expenditures of Can$262 million (US$170 million). The agreement is subject to regulatory approval and the necessary financing being in place.

Ondeo was selected following an RFP process undertaken by the Halifax Regional Municipality. The project forms part of the municipality’s efforts to clean up Halifax Harbour. Currently, more than 150Ml of untreated sewage flows into the harbour every day. Conditions are expected to improve as soon as the project is finished and operations commence.

The three WwTPs will be built at Dartmouth, Halifax and Herring Cove. Following construction, the municipality will manage the wastewater collection network. Ondeo’s proposal also includes a sludge
handling and management system to process sludge from the facilities for re-use.

Ondeo has formed a group of local partners to manage the project under the leadership of United Water, its US subsidiary, and Ondeo Degrémont, its water treatment engineering group. The partnership is known as the Halifax Regional Environmental Partnership.
