Lift Station 20-Year and 50-Year Life Cycle Evaluation

Before 1989, the city of Indianapolis frequently issued construction permits to developers for sanitary lift stations and associated infrastructure that became responsibility of the DPW to operate and maintain. Due to funding needs created by these facilities, the City amended their ordinance requiring submittal of a standardized 50-year life cycle cost analysis to justify a lift station over a gravity system prior to issuing a construction permit. DPW developed and implemented the methodology to compare the life cycle costs of these two sewer types. The revised analysis now includes a 20- and 50-year life cycle cost analysis including updated construction, labor, replacement parts, operation and maintenance, and rehabilitation costs.
