Halifax Water Integrated Resource Plan
IRP Implementation Plan
The total capital program net of asset renewal is about $88.6 million for 2023 to 2032
and a much more modest $64.8 million for 2033 to 2043 or approximately $8.9
million/yr. and $6.5 million on average respectively. The relatively small capital program
in the later years may in fact increase as additional information is gathered and
programs and projects are added in the intervening time period.
Approximately $536 million of the Recommended IRP budget is associated with the
proposed asset renewal program in the period 2023 to 2032 and $705 million in the
period 2033 to 2043. Approximately, 69% of the asset renewal effort in 2023 to 2032 is
associated with the wastewater system while 56% is associated with the wastewater
system in the period 2033 to 2043. Asset renewal for the water system in the period
2023 to 2032 is approximately 25% of expenditures and 30% in the period 2033 to 2043.
Storm system expenditures in the last 20 years of the plan increase considerably in
absolute terms but still are relatively small at 5% and 14% respectively. The average
annual asset renewal expenditure over this period is $54 million/yr. for the period 2023
to 2032 and $71 million/yr. for the period 2033 to 2043. This increase compared to the
period 2016 to 2022 likely results from a number of factors particularly in the last tenyear
period. Requirements for short-lived assets such as the M&E and ICA systems in
treatment facilities would need a second replacement, additional cohorts of linear
assets would reach their service life and require replacement and assets added in the
earlier portion of the planning period would begin to require replacement.
Other considerations with the periods for 2023 to 2032 and 2033 to 2043 of the
Recommended IRP include:
• Total program (i.e. planning, business systems improvements and improvements to
administrative facilities) related expenditures correspond to about 3% of the overall
2023 -2032 Recommended IRP expenditures and 19% of the overall 2033 -2043
Recommended IRP expenditures.
• Additional O&M costs associated with treatment facility or pumping upgrades or
expansions are increasing in these periods corresponding to about 6 % of the
overall 2023 -2032 Recommended IRP expenditures and 11% of the overall 2033 -
2043 Recommended IRP expenditures. At 11% the additional O&M cost represent a
significant fraction of the total expenditure for the period.
Details of all expenditures are presented in Volume 1 Appendix H.
7.5 RECOMMENDED IRP IMPLEMENTATION SCHEDULE
The master IRP schedule is presented in Figure 7.1. The figure is organized around the
drivers and objectives for each of the three systems. Specific projects are indicated in
the timeline as well as on-going programs. The overall plan spans the period 2013 to
2043.
