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.

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.
