The secondary treatment facility consists of two oxidation ditches equipped with propeller mixers and fine bubble diffused aeration. The dual mechanical system will allow operation in a anoxic/aerobic mode to provide nitrogen removal, power savings and improved biosolids settleability in the secondary clarifiers.

The complete treatment process consists of mechanical screening, oxidation ditches, secondary clarifiers, aerobic digester, and biosolids storage basin. An odour control facility to treat headworks emissions is provided.
