Ravensview Wastewater Treatment Plant Septage Receiving Station

Ravensview Wastewater Treatment Plant Septage Receiving Station

Project background

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 forcasted for the City's existing septage receiving station, located at the Cataraqui Bay Wastewater Treatment Plant in the west-end of the City of Kingston.  

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 forcemain to the general location identified for the station, as well as a connection tee on the site’s water service. The location previously identified was adjacent to the front yard setback line on the site, east of the main entrance road. This is the same location where the new facility will be constructed.


Services affected

  • Wastewater


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. More detailed information can be accessed through the City of Kingston DASH portal: www.cityofkingston.ca/business/dash.

Design and Construction

In general, the new Septage Receiving Station will consist of:

  • A remote unloading bay, located north of the existing fence line, capable of servicing two trucks simultaneously.
  • 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.
  • A two-storey building housing an electrical room, instrumentation and control room, odour treatment 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.
  • odour treatment unit providing reduction of odours from the pre-treatment unit and equalization tanks.
  • Two (2) equalization tanks to provide buffer of 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.

Schedule and Project Downloads

Utilities Kingston has awarded the construction contract to J.C. Sulpher Construction Ltd. While this work is not expected to impact sewer services in the area, residents may notice minor construction noise and traffic. The project has a 10-month construction duration.

June 2019 update - This project is currently in the commissioning stage, with an anticipated completion date of September 30, 2019.
