Poplar River First Nation Water Treatment Plant Upgrade

Poplar River First Nation retained JRCC to analyze the existing water and wastewater infrastructure and provide recommendations to meet the current and long-term servicing goals. The Feasibility Study reviewed water treatment and distribution options, raw water quality, disinfection, and wastewater collection and treatment.

A new WTP was recommended as construction and life cycle costs were similar to the option of upgrading the existing water plant. The treatment processes reviewed included conventional treatment, ballast assisted flocculation, slow sand filtration, dissolved air floatation, membrane filtration, ion exchange, pressure filtration and a UF/NF membrane system with SPES membranes was recommended.

Following completion of the Feasibility Study, Poplar River First Nation retained JRCC to complete the design and construction administration of a water treatment plant upgrade. The project included a new water treatment plant utilizing a UF (ultrafiltration)/NF (nanofiltration) treatment system with ultraviolet (UV) and chlorine as primary and secondary disinfectants, reservoir, low lift station, and raw water intake. Additional watermain looping was constructed to provide the new school with required pressures and flows. The existing water treatment plant building and reservoirs will be decommissioned once the new system is operational. The existing treatment plant building will be repurposed as a storage facility.

To maintain design and construction schedules, the treatment system was pre-tendered. Pre-tendering the treatment units provided a detailed and accurate footprint during design and allowed shop drawings to be included as part of the overall tender document. The water treatment plant has been constructed and commissioned and is currently in the warranty phase.
