City of Walker Infrastructure

Ulteig provided design engineering services for the infrastructure in the city of Walker, Minnesota. This included 20 city blocks of sanitary sewer, water main and storm sewer, along with street reconstruction. The underground utilities were almost 60 years old, so the project’s main objective was to extend system longevity.

The area was located near the elementary and high school in town. To avoid disruption of the first day of school, the team worked efficiently and relentlessly to complete the work both on schedule and under budget.

This rural town in north-central Minnesota was overdue for several infrastructure repairs, including reconstruction of a one-mile stretch of highway into a segment of city street with a multipurpose trail and sidewalk. Glyndon’s 50-year-old cast-iron wastewater collection piping was also in need of replacement.


Ulteig was selected by the Clay County Highway Department and City of Glyndon to complete design and construction for this entire project. During 2017, work began with taking the main arterial rural section of roadway and converting it to an urban section by widening and lowering it, adding a curb and gutter system, and incorporating a sidewalk on one side and a bike path on the other. Utilities beneath the roadway had to be lowered and regraded since they did not meet cover
requirements. The water distribution system within the reconstruction area also required replacement to ensure sufficient storm water drainage.


When this major renovation is completed in 2018, it will dramatically improve pedestrian safety and traffic flow through town, making Glyndon a more appealing prospect for potential new businesses and homeowners.

Ulteig designed a first-of-its-kind pretreatment system for waste generated at a rest area along I-94 managed by the North Dakota Department of Transportation. This innovative system can be easily modified for almost any rest area location at half the cost of other treatment alternatives. During construction, Ulteig also made facility updates to meet new ADA accessibility requirements.

The project timeline was significantly compressed but completed on schedule, in order to address concerns from the U.S. Fish and Wildlife Service that the work might affect nearby nesting birds and migrating whooping cranes

The City of Breckenridge’s 79-year-old water treatment plant was in such disrepair that it was featured in a segment on crumbling infrastructure on CBS Sunday Morning, a nationally broadcast television news show.

A competing firm originally designed a plant for the City and the bid came in several million dollars over the master plan estimate. At that point, the City decided to release that engineer and interview for a replacement. After proposals and interviews, the City hired Ulteig to value-engineer and build a new, more reliable and efficient source
of potable water for this community of 3,500 residents. The 1,000-gallon-per-minute water treatment plant needed to incorporate advanced lime-softening technology to remove iron, manganese and other hardening elements from the water.

In contrast to the original design, Ulteig applied its extensive experience, expertise and process efficiency to stay well below budget. As part of the Drinking Water Revolving Fund Program, the City received $5,000,000 in Principal Forgiveness Grants. Construction started on the new water treatment plant in September 2017 and is scheduled to be fully operational by the end of October 2018.
