A Class Environmental Assessment to investigate the major constraints regarding the Town’s wastewater treatment capacity. The study examined solutions aimed at maximizing the use of the Town’s available finances and infrastructure within the constraints of the stringent effluent limits of the receiving streams and the high I/I flows.

Based on an evaluation of the alternatives, the preferred option is to equalize the wastewater flows in each community in order to reduce the capacity of the treatment infrastructure and pumping stations and the size of the forcemains.

In order to reduce the capacity of the infrastructure in Tottenham, Beeton, and the Regional WWTP, equalization tanks will be constructed in each community. During periods of heavy storm events, some wastewater flows will be stored offline in the equalization tanks. Once the high flows subside, the wastewater will be pumped from the equalization tanks to the Regional WWTP for treatment. The equalization tanks will also be used to provide flow equalization of diurnal flows in each community to reduce the capital and operational costs.
