Sewage Treatment

Whitney and Tisdale Waste Water Treatment Plant

The Whitney and Tisdale Waste Water Treatment Plant which is completely computerized serves the communities of South Porcupine and Porcupine. This facility treats approximately 3200 cubic meters of wastewater per day, with the capacity of 6800 cum/day. Wastewater is pumped through seven pumping stations. It is treated, tested and disinfected, and the effluent is discharged into the Porcupine River within M.O.E. guidelines. The sludge is hauled to a private approved landfill site for proper disposal. The plant is a secondary treatment facility and operates on contact stabilization, which is a type of activated sludge process. Samples are sent every month to independent laboratories for tests of chemical parameters under M.O.E. guidelines. Samples are taken in the plant everyday and tested for dissolved oxygen, 30 minute settling test, and suspended solids. Some pumping stations are equipped with diesel generators for emergency situations.
