Olymel S.E.C. operates a pork processing plant in Cornwall, Ontario, which produces fresh and precooked bacon. After a fire broke out at the Olymel plant in Princeville, the company decided not to reopen this facility and to add the production of smoked ham to its Cornwall plant. This decision makes it necessary, on the short term, to expand the wastewater treatment system of the Cornwall plant. This processing plant has a design capacity of 735 m3/d (ultimate) / DBO5 1477 kg/d / NTK 28 kg/d
