Table 2.8 presents a summary of the composite program. The composite program corresponds to expenditure between the B and C levels for the water system and between the A and B levels for the wastewater and stormwater systems. The second step of asset renewal modeling, the composite asset renewal approach, was used in the financial model for the refined and short-listed plan analyses.
