Halifax Water Integrated Resource Plan
Integrated Resource Plan Development and Evaluation
The initial alternative resource plan matrix is presented in Table 5.5 for the 28 initial
plans. In order to aid presentation and discussion, the plans were organized into four
bundles based on variations in the level of overflow control and on the variations to the
RWWFP. The bundles are defined as follows:
• Bundle 1 – Modified RWWFP + Baseline Future Overflow Control
• Bundle 2 – Modified RWWFP + Enhanced Future Overflow Control
• Bundle 3 – Original RWWFP + Baseline Future Overflow Control
• Bundle 4 – Original RWWFP + Enhanced Future Overflow Control
