Integrated Resource Plan Drivers and Objectives<br />
4. INTEGRATED RESOURCE PLAN DRIVERS AND OBJECTIVES<br />
4.1 PURPOSE<br />
The purpose of this section is to present the three IRP drivers – Growth, Regulatory<br />
Compliance and Asset Renewal. The section also reviews the challenges, opportunities<br />
and risks associated with the drivers.<br />
4.2 GROWTH<br />
Growth is one of the key IRP drivers. All three-infrastructure systems will need to meet<br />
future growth demands.<br />
HRM provided a range of growth projections for use by the IRP project team. Based on<br />
the mid-range of those projections, the following growth estimates were developed and<br />
applied to the IRP and the RWWFP:<br />
• Residential growth to 2046 – 159,240 persons<br />
• Employment area growth to 2046 – 698.1 ha<br />
The locations of planned growth are provided in Volume 1 Appendix D in the IRP maps.<br />
4.2.1 Water and Wastewater<br />
The impact of growth was examined for both the water and wastewater systems. Most<br />
of the new growth is planned to occur in the urban core or adjacent areas. Very little<br />
growth other than infill is expected in the satellite communities. Hence the impacts<br />
were primarily on the large water and wastewater facilities and associated distribution<br />
or collection systems.<br />
Major facilities that will require expansion due to growth include:<br />
• The Lake Major WSP will be well within the WSP capacity but reaching the<br />
maximum water withdrawal permit limit at the end of 2046. There will be a need<br />
for exploring additional water supplies beyond the 2046 horizon.<br />
• The potential demand at the Bennery Lake WSP is predicted to surpass the water<br />
source safe yield and the maximum water withdrawal permit limit by 2016. The<br />
forecast demand is projected to exceed the WSP’s capacity between 2021-2026.<br />
Therefore, during the timeframe of the IRP there is a need to expand the Bennery<br />
Lake WSP, increase safe yield of the lake (e.g. using a dam or pumping from Grand<br />
Lake), and submit an application to NSE to request an increase in the Water<br />
Withdrawal Permit.<br />
