BACKGROUND
4
• Challenges identified in July 2021 GVS&DD Board Report• Constructability; solids-treatment capacity; schedule constraints; and cost increases• Compliance with regulatory deadline ~2034 (4 years late)• Estimated costs =$6.7B in 2021 dollars; $10.4B with escalation and risk reserve
• Recommending Revised Design Concept to address challenges• Committees: LWC – November 4; FIC – November 10• GVS&DD Board – November 26

REVISED DESIGN CONCEPT
6
• Concurrent construction of digesters and compact-footprint secondary treatment process (Membrane Bioreactor or Aerobic Granular Sludge)
• Offer capital cost savings in the order of 10%• Flexibility to validate performance and costs in preliminary design• Address commercial considerations as part of due-diligence
• What’s not changing• Tertiary level wastewater treatment • Odour control • Resource recovery opportunities• Ecological restoration projects• Iona Beach Regional Park integration

Sustainable Nature has inherent value and its protection for future generations is the foundation of what we do
Interconnected Our work nurtures the essential connection between people and natureReconciliation-focused Relationships with Indigenous Peoples are strengthened as we journey
together along the reconciliation pathwayInclusive Equity is integral to what we do, as we create an inclusive
environment for allCollaborative By working with others, we collectively steward the land to improve
the region’s livability and ecological healthKnowledge-based Decision-making is informed by data and science, and seeks to
incorporate Indigenous ways of knowingAdaptive Through learning, innovation, and evaluation, we sustain a culture of
adaptive management

DRAFT GOALS
17
1. The region’s important natural areas are protected in perpetuity2. First Nations have an active role in the planning and stewardship of
regional parks3. Everyone has the opportunity to benefit from exceptional experiences
in nature4. Regional parks adapt to change and contribute to regional resiliency5. Regional parks are sustainably managed and well-maintained to
ensure the safety of visitors and integrity of ecosystems
