A new wastewater treatment plant WWTP was required in the Town of Picton to accommodate predicted population growth. The facility had to be flexible to accommodate significant variations in population in Picton from permanent residents in winter to high summer tourist populations. The treatment plant was also required to treat septage and sewage holding tank contents.
Maple Reinders developed a design with five main components including preliminary treatment, septage receiving station, secondary treatment with extended aeration system, tertiary treatment, aerobic sludge digestion, and digested sludge dewatering (mechanical).
The associated system included the construction of a new pumping station, making use of existing infrastructure at the location of the existing WWTP, including the installation of two force mains to pump the raw wastewater up the hill towards the new facility
This project is the fourth phase in upgrades to the Peterborough Wastewater Treatment Plant and consists of a new inflow and infiltration system, screen building, WWC and maintenance buildings, a renovation and expansion to the existing administration building and process upgrades to the Park Street pumping station.
The first P3 project for municipal wastewater treatment in Canada, the Lac La Biche project involved the design, build (including procurement) and operation of a new 4,500m³/day Biological Nutrient Removal (BNR) wastewater treatment facility, in addition to a new lift station and forcemain the County of Lac la Biche in northern Alberta.
