Lift Station 20-Year and 50-Year Life Cycle Evaluation
Belmont AWT raw wastewater pumping capacity expansion study, design and bidding, and construction phase services were provided for this city of Indianapolis Consent Decree project. This project comprised the construction of 85 lft of piping revisions of existing 30-inch, 36-inch, and 42-inch piping and associated fittings and valves.
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.
