Halifax Water Integrated Resource Plan Executive Summary separation, sewer twinning, installation of deep storm sewers, and a range of solutions on the private portion of the network. The formal wet weather planning and I/I reduction pilot programs proposed in the current IRP will build on the preliminary analysis undertaken by Halifax Water for developing a deep storm sewer installation program and the current stormwater inflow reduction (SIR) program in place to address private side contributions to the system. The pilot program will inform the development of an I/I program for inclusion and funding in later years. ES 8. ES 8.1 RECOMMENDED IRP Recommended IRP Overview Based on the extensive analysis carried out through the IRP preparation a Recommended IRP was identified. The Recommended IRP components and timing are presented in Table ES-4. Table ES-4 IRP Driver Recommended IRP Components and Timing IRP Objective 1. Meet Current Nova Scotia Environment WWTF Permits to Operate. 2. Meet Current Nova Scotia Environment WSP Permits to Operate. 3. Meet Current Overflow Compliance. Recommended IRP Strategy • Five years to implement current WWTF compliance requirements. • Currently in full compliance. Continue current WQMP program and integrate into Water Master Plan. • Ten years to implement current overflow compliance requirements. Compliance 4. Meet Future WWTF Compliance. • Twenty years to implement future WSER compliance requirements for three HHSP WWTFs. • Ten years to implement future nutrient compliance requirements for 10 WTTFs by upgrading 8 WWTFs (Wellington, Frame, Mill Cove, North Preston, Aerotech Middle Musquodoboit, Lockview-MacPherson Uplands Park) plus Beechville-Lakeside-Timberlea (BLT) in the short term and consolidating Springfield Lake into Mill Cove WWTF and BLT WWTF into the Herring Cove WWTF in the long-term as per the RWWFP. 5. Meet Future Drinking Water Compliance. 6. Meet Future Overflow Compliance. 7. Meet Future Stormwater Quality Compliance. • Five years for Five-Year Capital Plan projects. • New program to control 59 overflows to a uniform level of 10 overflows per average year. Program is in addition to the RWWFP, which will offset the impact of growth on overflows. • Thirty years to implement enhanced overflow control. • Three years for stormwater quality assessment program development.

Halifax Water Integrated Resource Plan Executive Summary Table ES-4 IRP Driver Asset Renewal Growth Recommended IRP Components and Timing 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. ES 8.2 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. Table ES-5 Driver Regulatory Compliance Asset Renewal Growth 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.
