Halifax Water Integrated Resource Plan Recommended IRP and Analysis Table 6.3 Sensitivity of Treatment Expansion Requirements to Growth Rate Facility Current Capacity Current Flow/Demand (m 3 /d) Future Recommended IRP Capacity (m 3 /d) Future Baseline Growth Scenario Flow/ Demand (m 3 /d) Future High Growth Scenario Flow/ Demand (m 3 /d) Future Low Growth Scenario Flow/ Demand (m 3 /d) Facility Expansion Requirement Herring Cove WWTF 28,512 12,500 80,500 80,500 ~102,00 ~70,000 • Expansion required by 2031- 2036 under baseline scenario • Future WWTF capacity would need to increase under high scenario. Current expansion timing would need to accelerate. • Future WWTF capacity would decrease under low scenario. Current expansion timing could be delayed. At this stage the updated HRM Regional Plan is still under formulation and the current planning projections are an extrapolated estimate. Once these planning estimates are confirmed the water and wastewater functional plans should be reviewed and updated as needed. The sensitivity of the plans to growth should be re-evaluated at this point. Revision: 2012-10-29 Integrated Resource Plan 89 October 31 2012 Page 122 of 272
Halifax Water Integrated Resource Plan IRP Implementation Plan 7. IRP IMPLEMENTATION PLAN The Section presents the IRP Implementation Plan outlining the projects and programs making up the IRP in the 3, 10, 20 and 30-year timeframes and the master implementation schedule. The section also presents a high level view of IRP benefits, as well as discussing the incorporation of the IRP process into Halifax Water business planning. Finally, the section presents a series of recommendations with respect to LOS, programs and other aspects of water, wastewater and stormwater servicing. All costs are presented in $2012 unless otherwise noted. 7.1 RECOMMENDED IRP BENEFITS OVERVIEW Implementation of the IRP will provide a wide range of benefits addressing the three drivers – regulatory compliance, growth and asset renewal. High-level statements of the benefits derived from the IRP implementation are presented in Table 7.1. Table 7.1 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. 7.2 RECOMMENDED IRP EXPENDITURES 2013 – 2015 The three-year expenditures ($2012) from 2013 to 2015 associated with the Recommended IRP are presented in Table 7.2.
