6. IRP process will critically assess the potential
role of demand-side management (DSM)
practices and review the estimated impacts on
costs, demand, and capacity.
7. Initial IRP process will be completed consistent
with the data that will be available to Halifax
Water within the time line of this project.
Future enhancements to the IRP will improve
the accuracy and detail of the outcomes.

A full business case analysis of demand reduction was not feasible for this IRP due to considerable
limitations in available data and time needed to assess and analyse results. The approach that was
taken examined the benefit value gained from demand reduction for the wastewater system and
compared these values with literature-based information on flow reduction costs. The focus of the
analysis was a case study of the combined benefits of water efficiency and I/I reduction on the
expansion requirements identified under the RWWFP for the Dartmouth facility.
The foundation of an efficient asset renewal program is a solid understanding of the asset inventory
coupled with an understanding of current asset condition. This information along with cost data
provides the ingredients to develop a well-founded program. A review of available asset information
was carried out as part of IRP preparation. The data gaps identified are presented in Volume 3,
Appendix D and summarized in Table 4.5. Based on the review, it was clear that there were
significant limitations on asset condition data with water system linear assets having the most
recorded information and wastewater and stormwater linear assets having little or no recorded
condition data.
It was recommended to ensure adequate data collection and analysis components in all functional
and asset renewal planning for future IRP preparation.

4.1.1 Demand and Capacity Forecasts
TOR Requirement
1. IRP process will review and confirm existing water supply
demand forecasts (e.g. average and peak) over the
proposed planning horizon relative to identified
alternative growth scenarios and system enhancements
or constraints.
2. IRP process will document effects from Halifax Water’s
ongoing water loss control program.

Volume 3 Appendix A documents the existing water supply demand forecasts for the J.D. Kline
WSP, Lake Major WSP, Bennery Lake WSP, Small WSP Systems as well as growth impacts on the
water transmission system.
Halifax Water has achieved a considerable measure of success since adopting the AWWA/IWA
Water Loss Control Methodology in 2000. Halifax Water currently specifies a LOS for water loss.
Section 3.3 presents the details of the Halifax water Corporate Balanced Scorecard which is
presented in Volume 1 Appendix C.
