Volume 1 Appendix H presents the financial model for the Recommended Plan.
The Recommended Plan was analysed to assess the impact of three factors:
• The potential benefits of water demand reduction and I/I reduction on the Recommended
Plan.
• The level of asset renewal (A, B, C and composite) on end-of-period asset value.
• The population growth rate (high, baseline and low) on plan requirements.
The recommended IRP plan and implementation is presented in Table 6.1, Recommended IRP
Components and Timing. The timing of expenditures is shown in Figure 6.1, Recommended IRP
Expenditures by Year. The expenditures by driver are shown in Figure 6.2, Recommended IRP
Expenditures by Driver.
The 3-year expenditures from 2013 to 2015 associated with the recommended IRP are
presented in Table 7.2, IRP Recommended Expenditures 2013-2015 ($million).
Any significant increase in expenditure levels for the 3-year period is likely unrealistic from the
viewpoint of the increased revenue required and the impact on rates as well as Halifax Water’s
institutional capacity. Even with accelerated implementation it will require at least 2 to 3 years
to have adequate data and systems in place to obtain string return from scaled-up asset
renewal expenditures. The 2013-2015 expenditures should be reviewed and reprogrammed
with adequate ramp-up tie particularly for the asset management program. Other
considerations with the first three years of the recommended IRP are listed in Section 7.2.
Table 7.3 presents the IRP expenditure plan for 2016-2022 while Section 7.3 describes the
longer-term recommendations for 2016 to 2022. Table 7.4 presents the IRP expenditure plan
for 2023 to 2032 and 2033 to 2042 while Section 7.4 describes the longer-term
recommendations of these expenditure plans.
Based on the analysis carried out through the course of the IRP, Section 7.8 details the IRP
recommendations including ensuring adequate data collection and analysis components in all
functional and asset renewal planning.
