East Kingston Sewer Twinning
Utilities Kingston has initiated a Class Environmental Assessment (EA) study for the River Street Pump
Station Twin Forcemain Extension and Ravensview Trunk Sewer Twinning. As this project may impact
federal lands, the project team is working with the Canadian Environmental Assessment Agency to ensure
that screening requirements under the Canadian Environmental Assessment Act (CEAA) are also met.
The Ravensview Trunk Sewer is a large gravity sewer main that represents a critical and essential link in
the sanitary sewage collection system as it conveys all sewage from the Central and East portions of the
City of Kingston to the Ravensview Wastewater Treatment Plant. As identified in the recently completed
Sewage Infrastructure Master Plan for the City of Kingston Urban Area, the Ravensview Trunk Sanitary
Sewer is deteriorating and requires remedial action, lacks redundancy and has poor access for
maintenance. Consequently, the study will develop a strategy and confirm the preferred approach for
providing continuous, safe and efficient sewage conveyance for this vital link.
The recently installed twinned section of the River Street Sanitary Sewer Forcemain (Cataraqui River
crossing) currently terminates on the eastern shore of the Cataraqui River, after which it continues as a
single forcemain. The study will assess options for completion of the twinning of the forcemain and
rehabilitation or replacement of the remaining section of
original single forcemain. Given the interconnected nature of
the forcemain and the Ravensview Trunk sewer, the two
infrastructure needs must be evaluated concurrently.
The study is being planned under Schedule B of the Municipal
Class Environmental Assessment (October 2000, as amended
in 2007). Phase 1 of this process involves identification of the
problem or opportunity to be addressed by the project.
Phase 2 involves development of alternative solutions to
address the problem or opportunity. The alternative solutions
will be evaluated to identify a preferred solution that minimizes
impacts on the natural and social/cultural environment while
optimizing capital and operating investments.
Public and agency consultation is a key element of the Class
EA process. Two Public Information Centres (PICs) will be held
and project information will be available on Utilities Kingston
A mailing list for notification of project activities and PICs is now being compiled. If you wish to receive
notification of the Study activities, or if you have any questions regarding the study, please contact one of
