Discussion with ToP
Option Sets, Westside Update and Ministry Topic
(Adapted from upcoming Eastside Select
Committee Meeting)
October 20, 2015
Background
 Drivers for Option Set design
 Public Feedback, Technical Criteria
 Fulsome Evaluation as part of Phase 2
 Confirm the proposed Option Sets
 Acknowledge the 6 options already considered +
reprioritization (Eastside)
 Acknowledge the 3 options considered on Westside
 Illustrate links to Core Area options
Considering Option Sets
 Charter + Technical Criteria
 Leverage existing infrastructure
 Near probable water reuse opportunities
 Near heat recovery opportunities
 Neighborhood fit
 System reliability and connectivity
 Look lateral to Westside
Considering Option Sets
 4 Option Sets for Core Area
 Project Charter + Goals/Commitments encourage diverse
option sets
 From 1-plant to Distributed to uncover their relative
performance against criteria
 To allow the Committee(s) to refine criteria to suit a Core
Area approach for private market responses
Objective
Ensure the four option
sets provide for the
breadth of possibilities to
achieve the Goals and
Commitments

…Link the Westside and
Eastside Option Sets to
meet the Core Area
needs…
• Review the water and heat mapping from
Phase 1
Seek Purposeful
Distribution to
Optimize Resources
• Develop conceptual supply-demand maps for
greatest long-term potential recovery
• Strong alignment with growth centers and
green spaces
• 5 eastside locations
• Locates multiple
facilities near growth
centers
• Distributes facilities to
support on-demand
resource recovery
• Leverages
infrastructure where
possible
• 2 Eastside locations
• Option to reduce
pumping and land
needs in both
locations
• Increases reliability
with multiple facilities
• Provides mid-range
option between
centralized and
distributed
•
Note: consider two
additional plants on
Westside
1-Plant
2-Plant
4-Plant
9-Plant
Design
Shape the Charter goals into technical
criteria so we can design + assess Option
Sets based on Core Area needs and
aspirations.
Option Set 1
Option Set 2
Technical Criteria
Option Set 3
Option Set 4
Assess
Westside Update
 Discuss key themes for Westside Analysis
 Include west Saanich and west Victoria’s flow
 Explore 4-plant and 1-plant options and reflect on 2-plant
 Representative design process for costing discussion
 Emphasis on private sector responses to confirm solution
 Includes consideration to select municipal waste
feedstocks; needs much greater feasibility study
 Potential to forward 3 option sets to Core
Discussions With Ministry of
Environment
 Proposed Topics
 Regulatory exceptions feasibility: technologies,
augmentation
 Ministry knowledge of other suitable environments for
treated effluent (assumed tertiary +)
 Aquifer recharge
 Emerging contaminants
Thank You
