Lift Station Rehab

With treatment being the most important part of dealing with the collected wastewater of any entity the second most critical components are the lift stations that get it to the treatment plants. Lift stations have been around throughout the history of collecting and treating wastewater and, as time passes by, the age and condition of these lift stations have to be considered and dealt with.

Presentation will provide a successful approach to evaluating, designing and implementing the rehabilitation of existing wastewater lift stations to restore the lift station and extend the life of the structure and equipment. Things to look for in the detailed evaluation of the existing conditions will be presented and alternatives for material restoration and equipment replacement developed during the design phase will be discussed. Coordination and input from City staff is also important during development of the rehabilitation during the design phase. Last, but not least, issues to deal with during the implementation of improvements during the construction phase will be discussed.
