  • The Little River Pollution Control Plant was first commissioned in 1966 as an 18,000 m3/d (4 MIGD) plant.
  • It was expanded in 1974 to 36,000 m3/d (8 MIGD) providing phosphorus removal as well as conventional secondary treatment, or the activated sludge process, as it is scientifically termed.
  • The plant was upgraded and expanded in the early 90's to 73,000 m3/d (16 MIGD), with nitrification capabilities. This results in an effluent low in ammonia, thereby not being toxic to delicate aquatic life.
  • In the final upgrade, the sludge dewatering process was completed, with the latest technology in centrifugation and sludge cake pumping.
  • The quality of effluent is one of the best in the province, resulting in better stream life downriver of the plant than upstream.
  • A Biomonitoring program is underway at the plant with Rainbow trout and large mouth bass living in 100% effluent discharging to Little River.
  • The plant is controlled by the latest state of the art microprocessor technology.
