District 4
Capital Program & Projects
District 4 includes, in Carver County, the cities of Carver, Chaska, Cologne, Hamburg, Mayer, New Germany, Norwood Young America, Victoria, Waconia, and Watertown; and the townships of Benton, Camden, Dahlgren, Hancock, Hollywood, Laketown, San Francisco, Waconia, Watertown, and Young America. In Scott County, the cities of Belle Plaine, Elko New Market, Jordan, Prior Lake, and Shakopee; and the townships of Belle Plaine, Blakeley, Cedar Lake, Credit River, Helena, Jackson, Louisville, New Market, St. Lawrence, Sand Creek, and Spring Lake.
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 forcemains from each lift station. Where cost-effective, some lift stations will be replaced by deep gravity sewers using tunnel construction methods. The remaining lift stations will be rehabilitated and/or replaced as necessary. Single forcemains will be upgraded to dual forcemains where criteria support this strategy. Gravity sewers will be rehabilitated as necessary. River crossings will be inspected and rehabilitated as necessary. The major project areas are Victoria, Excelsior, Mound, and Wayzata, and the gravity sewers in Chanhassen, Eden Prairie, Minnetonka, Prior Lake, and Shakopee.
Capacity and condition assessments are being conducted along with regulatory reviews to identify system-wide lift station upgrades. These upgrades extend the life of facilities, reduce the risk of spills, and improve the safety of staff who operate and maintain lift stations.
This program provides funding to upgrade Environmental Services' ability to measure flows for billing, operational, and planning purposes and standardize meter equipment at similar facilities. Meter improvements include meter rehabilitation or replacement, planning meter installation, and new meter installation.
This program provides funding to address capital improvements at 8 regional wastewater treatment plants (WWTPs).
This project consists of a new lift station and a new dual forcemain. Ultimately, the dual 14-inch forcemains will be installed from Life Station 24 (L24) to the gravity discharge location in Lake Minnetonka Regional Park. This force main will connect to the previously installed Lotus Drive piping, a 2,600-foot segment of the forcemain that was constructed as part of the Lotus Drive with the City of Minnetrista. The forcemain construction will start at the west end of Lotus Drive and end on the east side of CR 44. The remaining 2,000 feet of the Waconia forcemain will be upgraded with this project as well, to align with work previously completed in Phases 1 and 2 of that project.
Replacement of the west 9,200 feet of 7508 is planned as part of Phase 2. The existing 14-inch cast iron pipe would be removed and replaced with 20-inch PVC and HDPE pipe. The existing route would be followed through Lake Waconia Park and in TH 5 right-of-way. A micro tunnel crossing of CR 92 is necessary.
This program includes miscellaneous projects to rehabilitate failing facilities, address Inflow and Infiltration (I/I) sources, and address general needs of the interceptor system not programmed into a region- or facility-specific program. This program also includes additional condition assessment work to complement the internal inspections work completed by operations. Office space planning and design to accommodate all the staff assigned to the Regional Maintenance Facility, and property transfer between Council and municipalities for public benefit.
This program provides funding for planning activities needed to support the Council’s overall wastewater reuse initiative.
The interceptor systems in Apple Valley, Eagan, Farmington, Lakeville, Savage, and other south area communities in need of rehabilitation and/or replacement as well as expansion to serve growth. The program will rehabilitate existing interceptor facilities, including gravity sewers and force mains, and analyze the system needs to accommodate growth.
This program provides funding for planning and implementation of projects to address renewal and capacity needs to improve performance for wastewater solids processing at the Blue Lake Wastewater Treatment Plant (WWTP).
In addition to the major projects, there will be interceptor rehabilitation, lift stations, and meter improvement projects located in the district.
