Riverbend Park Inc. - Environmental Compliance Approval (sewage)

This proposal is for a new Environmental Compliance Approval (sewage) for modifications to existing sewage works systems servicing facilities at Riverbend Park, located at 4838 Pioneer Trail, Puslinch, Ontario.

The Park has a total of 93 existing sites and 168 sites permitted. The existing sewage systems serving the park are reaching the end of their useful lifespan and require replacement. The daily design sanitary sewage flow for Riverbend Park is approximately 74,000 litres per day. The proposed replacement of the existing sewage systems includes the installation of an advanced tertiary sewage treatment system (BNA) designed to treat the peak daily flow of up to 72,400 litres per day, with the remaining residence flows being treated by the existing conventional sewage system.

The proposed tertiary sewage treatment system will incorporate nutrient reduction for total ammonia nitrogen and phosphorus, along with UV disinfection to meet required effluent quality standards. The treated sewage effluent will be directly discharged into a culvert that leads to the Speed River. The proposed system includes multiple components, including but not limited to:

• two equalization tanks
• primary and secondary treatment tanks
• a phosphorus removal system
• tertiary filtration

The treatment process will ensure that the effluent meets all applicable regulatory requirements.
