Sanitary Sewer Project
Contract No. ISD15-5067
The West Urban Community- Wastewater Collection System Master Servicing Plan Study completed in July 2012 recommended construction of the “Stittsville/Fernbank Diversion Trunk Sewer” to send wastewater flows to the Kanata West Pumping Station (KWPS) and reduce flows to the existing Hazeldean Pumping Station (HPS), eliminating the need for further HPS expansion for this growing development area.
As a result, the City of Ottawa is undertaking the preliminary and detailed design for the 900 mm diameter Stittsville Diversion Trunk Sewer (SDTS), which will divert wastewater from the Stittsville trunk sewer and convey the flow to the Kanata West Pumping Station (KWPS). Construction of the SDTS is expected to start in the fall of 2018 and will be substantially complete late in 2019. The alignment of the SDTS includes a diversion chamber on the Stittsville Trunk Sewer at Abbott Street. The proposed alignment extends north through the Fernbank Community lands along the north-south arterial/transitway corridor (future Robert Grant Avenue). Crossing under Hazeldean Road and Poole Creek, the diversion sewer will turn east on Maple Grove Road and tie into an existing sewer stub for KWPS.
Preliminary Design: Complete
Detailed Design assignment completion: Anticipated by June 30, 2018
Construction start: Fall 2018
Construction completion: Fall 2019
Approved project funds are $20 million.
A public information session is expected to be held in the summer of 2018, to present the design drawings, proposed construction methodology and schedule to the public. At this time attendees will be able to view the design, ask questions and provide comments on the construction impact of the proposed works.
