Infiltration Chamber: Life Cycle Costs (view source)

Below are capital and life cycle cost estimates for the two [[Infiltration chambers|infiltration chamber]] design scenarios over 25- and 50-year time periods. The estimates of maintenance and rehabilitation (life cycle) costs represent net present values. Operation and maintenance costs are predicted to represent 37% of total life cycle costs over the 25-year evaluation period, and increase to 49% of total life cycle costs over the 50-year period, due to cost associated with removal of sediment from the isolated chamber row pretreatment devices every 8 years.
