IRP Objective
8. Implement Optimal Level of Asset
Renewal.
9. Enhance the Reliability of Critical
Water and Wastewater Assets.
10. Ensure Existing Stormwater
System Adequately Sized for
Minor Storm Conveyance.
Recommended IRP Strategy
• Enhanced asset renewal based on risk-based composite
asset renewal program balancing failure consequences
and renewal expenditures. The composite specifies an
individual level of renewal for each asset category.
• Implement water system security program based on
Five-Year Capital Plan modified through the IRP.
• Ten years for stormwater capacity evaluation program.
11. Adapt to Future Climate Change. • Three years for climate change program development.
12. Reduce Energy Consumption,
Operating Costs and Greenhouse
Gas Contributions.
13. Provide Regional Water,
Wastewater and Stormwater
Infrastructure Needed to Support
Planned Growth.
14. Manage Flow Capacity
Allocations.
• Implement energy reduction projects based on the
Energy Management Plan as per the Five-Year Capital
Plan.
• Timing for wastewater projects/programs as per
RWWFP; timing for water projects/programs as per IRP.
• I/I, water efficiency and other demand reduction
projects.
• Timing as per RWWFP or as previously programmed in
Five-Year Capital Plan.

Recommended IRP Benefits
Implementation of the Recommended IRP will provide a wide range of benefits
addressing the three drivers – regulatory compliance, growth and asset renewal. Highlevel
statements of the benefits derived from the Recommended IRP implementation
are presented in Table ES-5.

Overview Recommended IRP Implementation Benefits
Benefits
1. Fully compliant wastewater system.
2. Continued fully compliant water system.
3. Enhanced environmental and public health through reduced overflows and WWTF loadings.
4. Continued high quality drinking water.
5. Fully meets LOS.
1. Fully functional water, wastewater and stormwater systems meeting their LOS at an
acceptable risk and reasonable cost.
2. Provides risk-based prioritized asset renewal expenditures for all infrastructure systems.
3. Balanced capital and O&M expenditures.
1. Water, wastewater and stormwater systems meeting the servicing needs of planned growth.
2. Sustainable water, wastewater and stormwater systems.
3. Support for continued community vitality through growth and new opportunity.
4. Balanced system expansion needs with reduction in demand for services.
