Looking at the pie charts below for each configuration we can see that they are all relatively close to being the same cost with a variation of a few hundred dollars between each over both a 25 and 50-year time horizon. The percentage of the [[Bioretention: Full infiltration|Full Infitlration]] configuration is greater than the other two due to the lesser cost of the overall installation for material and Installation, (no underdrains, no gravel storage layer or impermeable membrane, etc.).
→Life Cycle Costs
Below are capital and life cycle cost estimates for the three [[bioretention]] configurations over 25 and 50 year time periods. The estimates of maintenance and rehabilitation (life cycle) costs represent net present values.
