Mishkeegogamang First Nation – New Osnaburgh Water System Upgrade

Client: Mishkeegogamang First Nation

Location: Mishkeegogamang First Nation, Ontario, Canada

Mishkeegogamang First Nation is serviced by two water treatment plants – the Ten Houses WTP and the New Osnaburgh WTP. The New Osnaburgh WTP was a membrane system that provided sufficient water treatment, but was experiencing equipment performance issues. The community required additional reservoir storage capacity. JRCC prepared a Water Treatment Feasibility Study to review suitable options for a water treatment system that addresses the needs of the community and meets the Guidelines for Canadian Drinking Water Quality (GCDWQ).

JRCC was retained to complete interim repairs for the New Osnaburgh WTP. This project is currently in the warranty period.

In May 2022, JRCC was awarded the New Osnaburgh long-term water treatment project. The water treatment plant will meet provincial and federal standards and a 20-year design horizon and will continue to source raw water from Lake Couchessmoskog utilizing the existing raw water intake and supply piping. The scope of work includes the design and installation of nanofiltration treatment trains and pre-filtration skids, iron and manganese polishing via a greensand filtration system, UV and chlorine disinfection, settling tanks for process and reject water, and a new SCADA system to provide onsite and remote monitoring. The building and reservoir will be expanded and new distribution pumps and a new exterior genset installed. New administrative and functional spaces i.e. office, washroom, etc. will be constructed.  Service lines will be installed to 36 infill lots in the community from the existing piped distribution network. The upgraded systems will support community growth and provide fire protection.
