Greenbank Road Watermain

Project Status: 
Completed

Notice of Study Commencement

Municipal Class Environmental Assessment and Functional Design

The City of Ottawa has initiated a Municipal Class Environmental Assessment (Class EA) and Functional Design Study for the construction of a new 610mm diameter transmission watermain on Greenbank Road between Jockvale Road and south of the Jock River as shown on a Figure 1. The objective of this study is to determine the appropriate alignment of the proposed watermain within the realigned Greenbank Road and to determine the most appropriate method for the crossing of the Jock River, including the use of trenchless technologies.

Requirement for this new transmission watermain was identified in the 2013 City of Ottawa Infrastructure Master Plan as a necessary link to improve water supply and reliability in the Barrhaven South development area. In 2006 the City completed the Greenbank Road Class EA Environmental Study Report with the recommendation to widen and realign Greenbank Road from Strandherd Drive to Cambrian Road, including a new bridge structure over the Jock River. The proposed planning and construction for the 610mm diameter transmission watermain will be closely coordinated with the Greenbank Road project.

This study will be carried out in accordance with the requirements of Phases one and two of the Municipal Class EA. The study will include identification and evaluation of alternative alignments, selection of a preferred alternative and a functional design of the preferred alternative.

Project Update

The City of Ottawa is in a process of finalizing a Municipal Class Environmental Assessment (Class EA) Study for the construction of a new 610mm dia. transmission watermain along future Greenbank Road between existing Jockvale Road and south of the Jock River.  The objective of this study was to determine the appropriate alignment of the proposed watermain within the realigned Greenbank Road and the most appropriate method of crossing the Jock River, including the use of trenchless technologies.

Potential watermain alignment options are shown on the plan.

 Construction methods alternatives to cross the Jock River included open-cut, trenchless and bridge options on both sides of the future bridge structure and roadway.

  1. Open-cut construction – Option A1/A2/C
  2. Horizontal Directional Drilling  – Option A1/A2/C
  3. Tunneling/Pipe Jacking – Option A1/A2/C
  4. Pipeline Crossing on the Future Bridge – Option B1/B2

Based on the evaluation completed using technical requirements, social and natural environments, physical constraints and capital cost the preferred alternative for the 610mm diameter watermain is Alignment A-1 along east side of the proposed bridge structure and crossing of the Jock River by Horizontal Directional Drilling (HDD).

Proposed detailed design and construction for the 610 mm diameter transmission watermain was to be closely coordinated with the Greenbank Road widening and realignment project.  Since the trenchless technique is recommended for the Jock River crossing, the construction of the 610mm dia. watermain could proceed as a Class EA Schedule A+ project. However since due to the budget constraints the Greenbank Road project has been delayed for a few years the watermain project will need to go ahead before Greenbank Road widening and the new bridge over the Jock River is constructed. Since there is a requirement to acquire property right-of-way and construction easement for the 600 mm dia. watermain the Greenbank watermain project is going to be completed as a Schedule B. Report to Planning Committee and Council will be prepared to approve issuing Class EA Study Notice of Completion for the 30 day public review period.  If there is no objections to the Greenbank Watermain Class EA the project functional design report will be finalized.

Following the completion of a functional design report for this watermain,  the project will move to the detailed design and construction phase. The detailed design including the trenchless crossing of the Jock River by means of HDD will require additional field investigations, comprehensive borehole drilling program, updated river bathymetry and a risk assessment.

Class Environmental Assessment Report Available for Review

Class Environmental Assessment Report [ PDF 4.857 MB ]

The City of Ottawa has completed a Municipal Class Environmental Assessment (Class EA) Study for the construction of the new 610-millimetre diameter transmission watermain on Greenbank Road between Jockvale Road and south side of the Jock River.  This watermain is needed to meet water supply capacity and reliability requirements in the Nepean Town Centre and Barrhaven South development areas under future development conditions.

This Class EA process determined that the preferred solution is to construct the watermain along the east side of the future Greenbank Road right-of-way, using a trenchless construction technique (horizontal directional drilling) at the Jock River crossing.  It was determined that crossing the Jock River by open-cut methods would be problematic, due to geotechnical and environmental concerns. The design and construction of the full extent of the 610-millimetre diameter transmission watermain will be coordinated with the Greenbank Road widening and realignment project. Since the road realignment project has been deferred a number of years, it has also been determined that the watermain project can also be deferred without risk to service levels as development proceeds in the Barrhaven South area. However, there is a need to plan for one or more phases of the watermain to be constructed in coordination with anticipated development north of the Jock River in advance of the road realignment project implementation. 

This study was undertaken in accordance with the requirements for Schedule B projects under the Municipal Class EA process.  A Project File Summary Report has been prepared documenting the problem statement, existing conditions, identification and evaluation of alternatives, selection of the preferred solution, public and agency consultation as well as potential construction impacts and mitigation measures. The Report is available for public review at the following locations for a period of 30 calendar days, starting on Tuesday, November 28, 2017.
