South Urban Community Pump Station Upgrades & Pressure Zone Changes

Overview

Updated July 2014

Preliminary and Detailed Design

The City of Ottawa Infrastructure Master Plan (IMP) has identified several inter-related water infrastructure projects for the South Urban Community (SUC). These projects are needed to meet demands associated with urban growth, and to improve the reliability of supply to both existing and future development.

Pressure zone reconfigurations are planned for the SUC and Barrhaven areas which will create permanent water pressure changes within these areas.  There are four projects planned to create these reconfigured pressure zones:

  • Expansion of the Barrhaven Reservoir Pumping Station to augment supply to the Barrhaven pressure zone.
  • A larger diameter watermain along Fallowfield Road to reinforce the supply to Barrhaven from the Barrhaven Reservoir Pumping Station.
  • Upgrades of the Barrhaven Pumping Station, including a new watermain connection.
  • Upgrades of the Ottawa South Pumping Station, including a watermain connection.

The general timing for the construction of these projects is as follows:

  • Barrhaven Reservoir Pumping Station: December 2014 to May 2015
  • Fallowfield Road watermain: March 2015 to August 2015
  • Barrhaven Pumping Station: April 2015 to May 2016
  • Ottawa South Pumping Station: March 2016 to May 2017

The City of Ottawa has appointed Delcan Corporation for the preliminary and detailed design of this project.  Public Open House meetings are planned that will provide information on the construction activities and timing. 

The pressure variations that will occur in the SUC and the Barrhaven areas will be within City guidelines, for almost all water customers.  There will be a small number of water customers that will have a water pressure that is greater than those noted in the City guidelines.  For those customers, the installation of pressure reducing valves (PRV) will be required within their homes.  For those customers requiring a PRV, the City of Ottawa will be contacting them directly and providing them with the necessary information needed to allow the installation of the PRV device.  Area residents and the public will also be kept informed of the projects through the City of Ottawa Web site.

Welcome

The City of Ottawa Infrastructure Master Plan (IMP) has identified several inter-related water infrastructure projects for the South Urban Community (SUC). These projects are needed to meet demands associated with urban growth, and to improve the reliability of supply to both existing and future development. 

Pressure zone reconfigurations are planned for the SUC and Barrhaven areas which will create permanent water pressure changes within these areas. There are four projects planned to create these reconfigured pressure zones and increase the reliability to the SUC:

  1. Expansion of the Barrhaven Reservoir Pumping Station to augment supply to the Barrhaven pressure zone (Construction from October 2015 to July 2016)
  2. A larger diameter watermain along Fallowfield Road to reinforce the supply to Barrhaven from the Barrhaven Reservoir Pumping Station (Construction completed September 2015)
  3. Upgrades of the Barrhaven Pump Station, including a new watermain connection to the City’s water distribution system (Construction from June 2016 to May 2017)
  4. Upgrades of the Ottawa South Pumping Station, including a new watermain connection to the City’s water distribution system (Construction from Fall 2016 to Fall 2017)

Fallowfield Watermain and Barrhaven Reservoir Pumping Station Upgrade

Key Components:

  • New 400 mm diameter watermain along Fallowfield Road, from Barrhaven Reservoir Pumping Station (at Larkin Drive) to Cedarview Road.
    • This will be a trench reinstatement only for the new watermain, as Fallowfield Road is scheduled for a full asphalt overlay in 2016.
  • Barrhaven Reservoir Pumping Station Work
    • New Pump and replacement of an existing pump
    • New emergency power generator
    • Miscellaneous mechanical and electrical upgrades

Management of Impacts to Residents:

  • During construction one lane in each direction will be maintain on Fallowfield and Cedarview during peak periods and one through lane during off-peak periods.  Larkin Drive will be closed at Fallowfield for one weekend to facilitate completion of work through the intersection.
  • It is possible that some residents in the vicinity of Larkin Drive may have their water system interrupted when the new Fallowfield watermain is connected to the Larkin Drive watermain. Residents affected will be notified in advance and the work would be planned to minimize water interruption, such as during the night.
  • Safe and accessible path of travel for all pedestrians through and/or around the construction site will be maintained.
  • There will be no significant changes to existing water pressure for residents and businesses in Ward 3 during the construction of this infrastructure and once the new infrastructure is in operation.

Barrhaven Pumping Station Upgrade

Key Components:

• New 400 mm diameter watermain from pumping station to Foxfield drive.
• Four new pumps to replace existing pumps.
• Miscellaneous mechanical and electrical upgrades.

Management of Impacts to Residents:

• Safe and accessible path of travel for all pedestrians through and/or around the  construction site will be maintained.
• There will be no significant changes to existing water pressure for residents and businesses in Ward 3 during the construction of this infrastructure and once the new infrastructure is in operation.
