Halifax Water Integrated Resource Plan Appendices 1. OBJECTIVE TOR Requirement 1. IRP will identify the long-term servicing needs for Halifax Water’s water, wastewater, and stormwater infrastructure in a costeffective and reliable manner. 2. IRP will identify upgrade needs to address system reliability and safety, current and future capacity, and regulatory compliance. 3. IRP will consider the interrelationship of the water, wastewater, and stormwater systems. IRP Reference Sections 1, 4, 5, 6 and 7 Section 5.3 Volume 1 Appendix H Sections 5.4, 6.3.1, and 7.6 Volume 1 Appendix F Halifax Water embarked on the preparation of an Integrated Resource Plan (IRP) in order to define its overall program and resource needs for the next thirty years (2013 - 2043). The IRP responds to the combined requirements of regional growth, present and expected regulatory compliance and asset renewal. These three IRP drivers are presented in Sections 4.2, 4.3, and 4.4 respectively. Fourteen specific objectives were elaborated for the three drivers. The objectives reflect the current and anticipated compliance requirements (seven objectives) for the infrastructure systems; optimal asset renewal requirements as well as a number of related issues addressing water and wastewater system reliability, adequate stormwater capacity, adaptability to climate change and energy efficiency (five objectives); and two growth related objectives addressing the need to extend regional level servicing requirements and the requirement to manage flow capacity allocations. Specific projects and programs were allocated to each objective in the financial plan from existing Halifax Water initiatives and new program initiatives (Section 5.4), identifying the long-term servicing needs of Halifax Water’s infrastructure. Sections 6 and 7 identify how the IRP was developed and analysed in a cost-effective and reliable manner. 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, presented in Volume 1 Appendix H lists recommended projects and upgrade needs under each of the specific IRP objectives. Part of the IRP development was consideration of sustainable practices such as demand reduction programs (Section 6.3.1). For example water efficiency programs designed to reduce drinking water system demands also have demand reduction benefits for the wastewater system and should be considered under both a water and wastewater. The Five-Year Capital Plan and the RWWFP and thus the IRP contain a significant number of projects aimed at I/I reduction (Current Halifax Water Programs and Projects 2013 -2043, Table 5.2). This includes the SIR program for stormwater removal from the sanitary system and the I/I pilot program presented in Volume 1 Appendix F. The I/I program and the water demand reduction program both demonstrates the linkages among the three systems. The recommended planning programs in Section 7.6 will provide the needed data and insights to firmly incorporate integrated water management in the IRP update.
