Ravensview Wastewater Treatment Plant Septage Receiving Station
Septage receiving for Kingston and surrounding communities has historically been offered at the Cataraqui Bay Wastewater Treatment Plant (WWTP). At times when the Cataraqui Bay septage receiving station is out of service, septage hauling is received at Ravensview WWTP at the headworks of the facility. The existing station at Cataraqui Bay WWTP has reached the end of its service life and is scheduled for decommissioning as part of the ongoing Cataraqui Bay WWTP upgrade project. Due to site constraints and to reduce organic loading to the Cataraqui Bay WWTP system, septage receiving has been permanently relocated to the Ravensview WWTP.
The 2004 Municipal Class Environmental Assessment (Class EA) Update conducted for the Ravensview Wastewater Treatment Plant (WWTP) included the provision of a new septage receiving station. During the preliminary design phase for the upgrade project, the septage receiving station scope of work was postponed to coincide with the future end of service life
Provisions for future construction of the Ravensview WWTP septage receiving station were constructed as part of the 2004 project, including the installation of a 100 mm
In the 2004 Municipal Class Environmental Assessment Update for Ravensview WWTP, it was recommended that a septage receiving station be implemented at the plant. The Environmental Study Report (ESR) Update was filed on May 28, 2004 and the allowed “lapse of time” of five years has now passed between the ESR filing and commencement of construction.
Under the framework of the Municipal Class EA, implementation of a new septage receiving station at the Ravensview WWTP falls under the description of Schedule ‘A’ (pre-approved activities) undertakings. Although the project is a Schedule 'A' undertaking, Utilities Kingston has elected to elevate the schedule to Schedule 'A+' by providing public notification of the project prior to implementation.

The new works are designed to be in compliance with all applicable regulations. Utilities Kingston has received Ministry of the Environment and Climate Change (MOECC) Environmental Compliance Approval (ECA) Air and Noise, and Sewage for the works. An application for Site Plan Control has been made and is currently under review with the City of Kingston.

- A new ring road, which will convey septage haulers only and provide enough space for two (2) trucks unloading with space for trucks to queue.
two-storeybuilding housing an electrical room, instrumentation and control room, odourtreatment room on the upper level and a pre-treatment unit on the lower level.
- A pre-treatment unit providing a rock and grit trap, followed by screening.
Atreatment unit providing odour reductionof odoursfrom the pre-treatment unit and equalization tanks.
- Two (2) equalization tanks to provide
bufferof extended peak hourly flows, complete with a submersible pump to convey pre-treated sewage to the existing 100 mm glass-lined forcemain.
Construction of the works will require rock removal. Construction activities will be carried out in accordance with applicable City of Kingston Bylaws. There will be no interruption to customer servicing.
