Mary's Creek Lift Station Reconstruction

About. This project will replace an aging sanitary sewer lift station that has served the Shadycrest area for 30 plus years. The current facility consists of a dry pit design with pumps and electrical controls located below wet well operational levels resulting in occasional loss of equipment due to wetwell backflows. The new lift station is designed to meet our current standards which will improve reliability by removing the dry pit and moving equipment above ground, improve efficiency with new submersible pumps and reduce maintenance costs.

Scope. The work will consist of the installation of a precast concrete wet well, precast valve box, and installation of City-standard submersible pumps, along with associated piping and electrical and control equipment to completely replace the existing lift station. The scope of work will also include paving repairs, traffic control, and a storm water pollution prevention plan.
