Recommended Alternative
Resource Plan 40‐4
The total 3‐year and 30‐year NPV for the recommended plan inclusive of capital and O&M costs
are $345 million and $2,579 million, respectively.
Annual Plan Expenditures
The timing of expenditures (in $2012) for the recommended Alternative Resource Plan 40‐4 is
shown in the top figure presented on the previous page, which indicates significant
expenditures around years 10, 20 and 30. This corresponds to the following projects:
Year 10 – WWTF Nutrient Upgrades.
Year 20 – WSER HHSP WWTF Upgrades.
Year 30 – Enhanced Overflow Control Program.
Over the 30‐year period the average expenditure under the Recommended Alternative
Resource Plan is $131 million/yr.
Expenditure by Driver
The IRP responds to the combined requirements of regional growth, present and expected
regulatory compliance and asset renewal.
The expenditures by driver for the recommended Alternative Resource Plan 40‐4 are shown in
the bottom left Figure presented on the previous page. Approximately 54% or $1,385.1 of the
expenditures including O&M costs are associated with asset renewal and the remainder split
between growth (23% or $598.4) and compliance (23% or $595.2) for the water, wastewater
and stormwater systems.
Water, Wastewater, and Stormwater Cost Breakdown (NPV)
The expenditures for the individual water, wastewater, and stormwater systems, as per the
recommended Alternative Resource Plan 40‐4, are shown in the bottom right Table presented on the
previous page. The expenditures are divided into the objectives described below and are inclusive of
O&M costs.
Fourteen specific objectives were elaborated for the three drivers. The objectives reflect the current and
anticipated compliance requirements (seven objectives) for the infrastructure systems (Objectives 1
through 7); 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 (Objectives 8 through 12); and two growth related objectives addressing the need to
extend regional level servicing requirements and the requirement to manage flow capacity allocations
(Objectives 13 and 14). Specific projects and programs were allocated to each objective in the financial
plan from existing Halifax Water initiatives and new program initiatives identifying the long‐term
servicing needs of Halifax Water’s infrastructure.
