Rainwater Harvesting & Cisterns: Life Cycle Costs (view source)

==Life Cycle Costs==
Below are capital and life cycle cost estimates for the below-ground concrete cistern design configuration 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 19% of total life cycle costs over the 25-year evaluation period, and increase to 27% of total life cycle costs over the 50-year period, due to periodic cleaning of cistern tank and replacing components (pump and pressure tank).
