Mattagami River Wastewater Treatment Plant
The Mattagami River Wastewater Treatment Plant serves the communities of Timmins, Mountjoy, and Schumacher. This facility treats approximately 20 000 cubic meters of wastewater per day with a capacity of 52, 500 cubic meters per day. Wastewater is pumped through eleven pumping stations. It is treated, tested and disinfected, and the effluent is discharged into the Mattagami River within M.O.E. guidelines. The solids are treated anaerobically, methane gas produced in the digesters is used for digestion and as a source of energy for the boilers. The sludge is hauled to a private approved landfill site for proper disposal. The plant and some pumping stations are equipped with diesel generators for emergency situations.
Whitney and Tisdale Wastewater Treatment Plant
