District 4 Projects

Capital Program

All of Carver County except for the city of Chanhassen and all of Scott County except Spring Lake Township, Credit River Township, Cedar Lake Township, New Market Township and the city of Elko New Market. Excluded is the Scott County portion of the city of New Prague.

Blue Lake Plant Improvements: Project 8018

This major project, that renewed the plant’s liquid and solids process systems, is nearing completion. The remaining project under construction, includes process improvements and structural improvements to plant buildings, slide gates and work in the tunnels.

Blue Lake System Improvements: Project 8028

This project provides improvements to meet the long-term conveyance capacity, reliability, and rehabilitation/replacement needs of the Blue Lake Interceptor System. This system includes gravity sewers, 29 lift stations, and single forcemains from each lift station. Where cost effective, such as in the Victoria area, some lift stations are being replaced by deep gravity sewers using tunnel construction methods. In some cases, small lift stations will be consolidated. The remaining lift stations will be rehabilitated and/or replaced as necessary. Single forcemains will be upgraded to dual forcemains. Gravity sewers will be rehabilitated as necessary. River crossings (Chaska-Shakopee and Eden Prairie-Shakopee) will be inspected and rehabilitated as necessary. The five major project areas are Victoria, Excelsior, Mound, and Wayzata, and Gravity Sewers (Chanhassen, Eden Prairie, Minnetonka, Prior Lake, and Shakopee).

Chaska Lift Station: Project 8039

Provides for a new, larger pumping station at the former WWTP site, to provide long-term capacity to serve Chaska and Carver.

Lift Station Rehabilitation: Project 8055

Consists of improvements to Lift Stations L-13, L-30, L-34, L-56, L-66, and L-73. The project will replace obsolete, aging equipment and increase the lift stations' pumping capacity. A portion of the L-30 forcemain in Crystal (1-BC-453) will also be replaced under this project. Other Lift Stations to be rehabilitated include L-01, L-02, L-05, L-15, L-33, L-35, and L-57. In some cases the lift station’s forcemain will be included in the rehabilitation.

Regional Plant Improvements: Project 8078

The project originally consisted of electrical improvements to mitigate arc flash potential and for the replacement of electrical equipment as needed at the regional plants. It was expanded to include improvements at the St. Croix Valley, Eagles Point, Empire, Hastings, and Blue Lake Plants. The Eagles Point Plant project includes replacement of the existing membrane diffusers with ceramic diffusers. The Blue Lake project includes improvements to optimize digester gas production and utilization, as well as improvements to the plant’s electrical system. The project includes a plant-wide Wi-Fi network at each of the regional wastewater treatment plants as well as miscellaneous improvements at the Hastings Plant, Empire Plant, and East Bethel Water Reclamation Plant.

Waconia LS/FM Rehabilitation: Project 8083

This project consists of lift station improvements and replacement of the older of two forcemains.

Wastewater Reclamation Facilities: Project 8091

Provides funding for the acquisition and planning of sites for future wastewater reclamation facilities and for planning for wastewater reuse where collaboration opportunities have been identified.

In addition to the major projects, there will be energy conservationinterceptor rehabilitation, lift stations, and meter improvement projects located in the district.
