Most communities have one or more lift stations that keep wastewater moving along on its journey from individual properties to a wastewater treatment facility. Many existing lift stations were installed decades ago and are at risk of failing if aged and corroded components are not addressed. When lift stations fail, wastewater backups and overflows happen. Eventually every lift station need repairs and upgrades for reliable operation and to meet changing demands. Engineers play a central role in lift station rehabilitation.
This course focuses on the engineering of lift station rehabilitation, including master planning, condition assessments, performance assessments, defining design flows, pump selection, intake design, materials selection, and tips for construction oversight. Common lift station configurations are explained with example figures. Also covered are the advantages of each type of lift station, selecting the number and size of pumps, and selecting constant speed versus variable speed drives.
Learn the steps in a typical rehabilitation process and gain practical advice to help ensure that a rehabilitated lift station will last many years into the future. Practical inspection methods and field measurements are addressed along with strategies for sequencing of work and developing rehabilitation scopes that correct existing deficiencies while accommodating future wastewater demands. The course emphasizes engineering judgment, multidisciplinary coordination, constructability, reliability, and long-term maintainability.
