The wastewater treatment facility at the Town of Ponoka consisted of anaerobic primary lagoons followed a facultative cell and three storage cells. The storage cells discharge into the Battle River. As a result of population growth, Ponoka was discharging twice per year, which exceeded Alberta Environmental Protections’ (AEP) requirement of a single discharge. If the current treatment process were to remain the same, the capacity of the storage cells would have had to be increased, requiring substantial additional land area and high cost civil construction. Alternative treatment methods were reviewed to determine a more cost effective solution.
