Table 5.6 shows an overall variation in 30 year NPVs of about $1 billion (capital and
O&M). As indicated in Table 5.6, Plan 25-1 with A Level compliance timing for Objectives
1, 2 and 4 and A level asset renewal, the unmodified RWWFP and Enhanced Overflow
Control is the most expensive. Plan 1-1 with C Level compliance timing for Objectives 1,
2 and 4 and C level asset renewal, the Modified RWWFP and Baseline overflow control is
the least expensive.
The impact of the drivers and program elements were subjected to the analysis of
variations, which are explored further below.
