Halifax Water Integrated Resource Plan Appendices 3. SCOPE TOR Requirement 1. IRP process will characterize current condition of the infrastructure assets and identify information gaps. 2. IRP process will document existing capacity of infrastructure components. 3. IRP process will develop demand forecasts for future water supply, and future wastewater and stormwater flows and capacity requirements. 4. IRP process will identify jurisdictional responsibilities and policies related to overall water resources management (including water supply and extraction rates, source protection, groundwater resources, groundwater recharge practices, flood and stormwater management, flood protection, etc.). IRP Reference Sections 3.4 and 4.4.2 Volume 3 Appendix D and Volume 3 Appendix E Section 3.4 Volume 3 Appendix A and B and RWWFP Section 4.2.1 Volume 1 Appendix D RWWFP Section 3.2 Section 3.4 describes the current water, wastewater, and stormwater infrastructure assets. A review of the available asset information was carried out as part of IRP preparation. The data gaps identified are presented in Volume 3, Appendix D and E and are summarized in Table 4.5, Asset Data Gaps. Section 3.4 summarizes the existing capacity of the water and wastewater, infrastructure components, A review of the water system is presented in Volume 3 Appendix A, the WWTFs in Volume 3 Appendix B, the collection system in the RWWFP The storm system information regarding capacity was very limited. Portions of the drainage system (combined areas) were analysed under the RWWFP The impact of growth was examined for both the water and wastewater systems. Most of the new growth is planned to occur in the urban core or adjacent areas. Very little growth other than infill is expected in the satellite communities. Hence the impacts were primarily on the large water and wastewater facilities and associated distribution or collection systems. The details of growth impacts on both water and wastewater systems are provided in Volume 3 Appendices A and B respectively. Volume 1 Appendix D and the RWWFP provide additional details of growth locations and distribution. Growth is not likely to have a significant impact on the overall stormwater system, as there are very few existing regional facilities. However, with growth, the length of the stormwater network (both piped and ditches) will be expended and therefore impact the ongoing asset management and operational programs over time. Sewer separartion is an option for asset renewal projects, leading to increased stormwater infrastructure over time. Halifax Water presently operates and manages all elements of the water and wastewater system but only specific portions of the stormwater system. Figure 3.1, in Section 3.2 presents the stormwater responsibilities graphically. The HRM Regional Plan presently requires the preparation of a Regional Stormwater Functional Plan (RSWFP) by HRM. The preparation of the RSWFP should be used to provide the “road map” that will resolve the jurisdictional and other issues surrounding stormwater management.

Halifax Water Integrated Resource Plan Appendices TOR Requirement 5. IRP process will identify risks and uncertainties that may influence Halifax Water’s delivery of water, wastewater, and stormwater services. 6. IRP process will develop a set of performance requirements (including social and environmental constraints) and criteria for prioritizing needs and evaluating the various plans. 7. IRP process will develop realistic supplyside and demand-side options to meet current supply and capacity constraints and needs, future growth, and current and projected environmental requirements. IRP Reference Section 4.5 Sections 5.3 Section 6.2 The three IRP drivers impact each of Halifax Water’s infrastructure systems to varying degrees. The principal risks to Halifax Water associated with these impacts are connected to the uncertainty of future requirements. A second and equally important risk results from the limitations of available data supporting the IRP decision process. Specific drivers Uncertainties and Risk are discussed further in Sections 4.5.1, Compliance Challenges, Opportunities and Risks; 4.5.2, Asset Renewal Challenges, Opportunities and Risks; and 4.5.3, Growth Challenges, Opportunities and Risks. Fourteen specific objectives were elaborated for the three IRP drivers (Regulatory Compliance, Asset Renewal, and Growth). The objectives reflect the current and anticipated regulatory compliance requirements for the three Halifax Water infrastructure systems (Objectives 1 through 7, Table 5.1, Regulatory Compliance and Asset Renewal Related Objectives) and upgrade needs to address system reliability (Objective 9, Table 5.1), as well as current and future capacity (Objective 10, 13 and 14, Table 5.1). The IRP financial plan lists recommended projects and upgrade needs under each of the specific IRP objectives. Table 6.1, presents the Recommended IRP Components and Timing Objective 1 comprises of projects and programs to meet current NSE WWTF Permit to Operate compliance, the timeframe to implement current compliance is 5 years. Objective 2 comprises of projects and programs to meet current NSE WSP Permit to Operate compliance. The water system is currently in full compliance. Objective 3 comprises of projects and programs to meet current Overflow compliance. The timeframe to implement current compliance is 10 years. Objective 10 comprises of projects and programs to ensure existing stormwater system is adequately sized for minor storm conveyance. The timeframe to implement is 10 years for program development. Objective 13 and 14 comprises of projects and programs to provide regional water, wastewater, and stormwater infrastructure needed to support planned growth and manage flow capacity allocations, respectively. The implementation timing to support planned growth is as per the RWWFP. Additional future projected environmental requirements are outlined in ToR#65, below.
