Overview
Sun Prairie Utilities (SPU) has been located in Downtown Sun Prairie for over 50 years. In 1972 the population was over 10,500. By 1986 the city had grown to around 14,400 and swelled to over 20,400 by the year 2000. A few expansions took place throughout the years but have not kept up with the growth of the city. In 2021, the U.S. Census Bureau reported the number of residents in Sun Prairie had grown to approximately 36,100.
Why a new building?
The current building is not keeping up with the utility demands resulting from Sun Prairie's rapidly growing city. The 19,000-square-foot, 50-year-old facility forces offsite storage of numerous vehicles and equipment. Similarly, limited to no space exists for new employees in the 9,000-square-foot, 22-year-old main office area. Additionally, the mechanical systems of the existing facilities are aging and require escalating operation and maintenance costs. The 83,000-square-foot new facility will incorporate various sustainability and technological advancements and is expected to provide the utility with adequate space to grow for the next 30-50 years.
When does SPU move?
Sun Prairie Utilities’ office moves from its Main Street location in mid-December. The Main Street facility will tentatively close on Wednesday, December 17, and the new Linnerud Drive location opens on Monday, December 22, 2025. *Note: The dates are subject to change.
What is the new address?
The new SPU operations facility (office) is located at 510 Linnerud Drive, Sun Prairie.
If I need to mail a check, what would be the address?
The mailing address would still include our PO Box, but with a new street address.
PO Box 867,
510 Linnerud Dr.,
Sun Prairie, WI 53590
Is the phone number the same?
Yes, customers can still reach us at (608) 837 - 5500.
Will there still be a drive-up window and deposit box?
Yes, the new facility has a drive-up window for customers to use. SPU will continue to have an after-hours deposit box, as well.
Have the office hours changed?
No, SPU’s usual office hours have not changed from Monday through Thursday, 7:00 a.m. to 4:30 p.m., and Fridays, 7:00 a.m. to 11:00 a.m.
Is the new building ADA-compliant?
Yes, the building is ADA compliant. ADA compliance indicates that the building meets the requirements of the Americans with Disabilities Act. Building accessibility has been addressed through the design of specific features such as properly graded ramps, accessible parking spaces, doorways, visual signage, entrances, restrooms, and common areas. People with physical, visual, or hearing impairments should be able to access and use the building safely and independently.
How will the new building help the community?
The new facility is being designed to fit the needs of the community. The additional space for vehicles, equipment, materials, and staff will increase operational efficiency and minimize the length of potential service interruptions. The public will continue to have access to customer service, attend meetings, and the new community room will be available for use.
Progress
The Wisconsin Public Service Commission has approved the construction authorization application.
Construction Bids were considered at the May 20, 2024, Utilities Commission meeting, from which Miron's base bid incorporated geothermal and a basement, along with alternates to include 435kW of rooftop solar, a bulk-fill water station, and a 30-foot extension to the west wall of the garage area was selected. With the incorporation of many sustainability and energy efficiency initiatives, the project continues to seek LEED Gold Certification. The overall estimated project costs are $22.5M (including Focus on Energy Incentives and IRA Tax Credits) or $1.9M below the original budget.
The Groundbreaking Ceremony was on Thursday, July 11, 2024. Please watch for a ribbon cutting and public open house after the facility is finished.
