Life cycle cost analysis is used when comparing life cycle costs for different pumping solutions. Future energy costs and miscellaneous annual costs are calculated into a capitalized present day value based on the selected interest rate. The calculation is based on the summation of the cost elements that make up the LCC.
LCC = (Cic + Cin + Ce + Co + Cm + Cs + Cd + Cenv)
C = cost element
ic = initial cost, purchase price (pump, system, pipe, auxiliary services)
in = installation and commissioning cost (including training)
e = energy costs (predicted cost for system operation, including pump driver, controls, and any auxiliary services)
o = operation cost (labor cost of normal system supervision)
m = maintenance and repair cost (routine and predicted repairs)
s = down time cost (loss of production)
d = decommissioning/disposal cost (including restoration of the local environment and disposal of auxiliary services).
env = environmental cost (contamination from pumped liquid and auxiliary equipment)
