Project #8055, Lift Station Rehabilitation

Description:

This project consists of improvements to Lift Stations L-3, L-6, L-7, L-10, L-13, L-30, L-35, and L- 56 and L-66. The project will replace obsolete, aging equipment and increase the lift stations pumping capacity. The L-7 forcemain will also be replaced under this project.

Project Map

Purpose and Justification:

The Interceptor System Master Plan (2002) recommended lift station improvements. This project will renovate these aging lift stations, which are 30 to 40 years old and will increase capacity as needed. The other, older lift stations in the system are generally part of a larger interceptor system project, i.e. Blue Lake, Northeast, or Northwest.

Lift Station Projects

Project #805510

Facility	Location	Scope
L-3	Hugo	Work at this lift station will include installation of two 75 hp pumps, suction valves at two locations, and necessary header piping.
L-6	White Bear Lake	A new three-pump submersible pumping station will replace the existing factory build station installed in 1961.
L-10	Little Canada	Anew submersible pumping station will be installed at the present site to replace a factory built pumping station installed in the 1970’s. Upon completion, this facility will be re-conveyed to the City of Little Canada and is being designed and constructed to meet City requirements regarding its configuration, pumps and control system.
L-56	Eagan	A new two-pump submersible pumping station will replace a factory- built station constructed in the 1960’s. This facility will be re-conveyed to the City of Eagan and is being designed and constructed to meet City requirements regarding its configuration, pumps and control system.

Project #805520

Facility	Location	Scope
L-7	Mahtomedi	The work will include installation of three new dry-pit pumps and motors and the necessary pipe header modifications to allow use of either or both forcemain barrels. A new supervisory control and MCC system will be provided and the HVAC system will be replaced
L-30	Crystal	This station, originally constructed in 1955, will receive a complete overhaul. New pumps, valves, and piping will be provided. Supervisory controls and the MCC will be replaced.
L-35	Mounds View	This pumping station, originally constructed in 1966, will receive a complete overhaul. New pumps, valves, and piping will be provided. Supervisory controls and the MCC will be replaced.

Project #805530

Facility	Location	Scope
L-7 FM	Mahtomedi	The present forcemain will be replaced and abandoned. The forcemain will be realigned along Lincolntown Road and Long Lake Road and discharge into interceptor MSB 7121. The forcemain will be approximately 10,000 lf long and will consist of twin 16-inch diameter forcemain barrels with cross-over structures. (Location Map)

Project #805540

Facility

Location

Scope

L-13

Burnsville

The pumping station is in need of a total rehabilitation. New pumps, valves, and piping will be provided. Supervisory controls and the MCC will be replaced. and the lighting, plumbing and mechanical systems will be replaced. Rehabilitation of the wet well was completed in 2007.

A parallel forcemain barrel will be installed to the present discharge location. The option to discharge into a siphon barrel will be maintained. The existing forcemain will be rehabilitated to remedy the reaches where breaks have occurred.

L-66

Savage

The present facility was constructed in 1988. The pumping station and dual barrel forcemain are in good condition. Capacity improvements are required to boost the station capacity and meet the projected service requirements. A fourth pump will be installed in the existing station. In addition the project includes modifications to the pipe manifold, and control system. The wet well will be cleaned and coated with a corrosion resistant coating. The completed improvements will deliver the needed capacity utilizing both forcemain barrels.
