As can be seen, regardless of design configuration, Material & Installation expenses represent the largest portion of total construction costs (75%).

Below are capital and life cycle cost estimates for the [[Infiltration chambers|infiltration chamber]] design scenario over 25- and 50-year time periods. The estimate of maintenance and rehabilitation (life cycle) cost represents 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.
