| Project #8022, Lift Station L-12 Improvements | |
Description: This project provides for the construction of a field-fabricated submersible type four-pump lift station located approximately 300-feet north of the existing L-12 site. The new lift station will have a rectangular split wet well and a valve vault. A superstructure will house a control room, emergency generator, ventilation, heating, and sanitary facilities. One hour of emergency storage at the average flow will be made available by upsizing the 300-linear feet of inlet gravity sewer to 90-inch diameter. The lift station will discharge into a new 16-inch diameter forcemain. The existing forcemain will be cleaned, inspected, and remain in service as a redundant barrel. The existing lift station will be demolished when the new station becomes operational. |
Located in St. Paul on Point Douglas Road, the existing Lift Station L-12 is a manufactured-type station with a capacity of 7.8 MGD. The lift station equipment is old and obsolete, and at the end of its useful life. The project will replace the existing lift station with a reliable efficient facility.
