Halifax Water Integrated Resource Plan
Integrated Resource Plan Development and Evaluation
The IRP drivers were already discussed in Section 4. The remainder of Section 5 presents
each of the steps shown in Figure 5.1 starting with the development of IRP objectives.
5.3 IRP OBJECTIVES
Following the analysis of the IRP drivers presented in Section 4, fourteen specific IRP
objectives were developed. The objectives were based on the current Halifax Water LOS
as described in Section 3 and in Volume 1 Appendix C. The objectives reflect the current
and anticipated compliance requirements (seven objectives) for the three 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 servicing requirements and the
requirement to manage flow capacity allocations. The specific objectives and related
LOS are presented in Table 5.1.
