CORE DOMAINS
Wisconsin Utility Contractor Licensing and Regulations (SPS 305, Admin Code)
Earthwork, Excavation, and Compaction Standards
Gravity and Pressure Water Distribution Systems
Sanitary Sewer and Storm Drainage System Construction
Trench Safety, Shoring, and OSHA Compliance
Pipe Materials, Jointing, and Bedding Specifications
Pavement Restoration and Asphalt Patching
Wisconsin Department of Transportation (WisDOT) Specifications
Traffic Control and Work Zone Safety (MUTCD)
Environmental Protection, Erosion Control, and DNR Compliance
This practice assessment is designed for candidates preparing for the Wisconsin Utility Contractor Licensing
Examination. The examination evaluates the technical competencies required to construct, install, and repair
underground utility systems, including water mains, sanitary sewers, and storm drains, in compliance with the
,Wisconsin Administrative Code (SPS 305), WisDOT Standard Specifications, and local municipal requirements. Key
skills assessed include interpreting construction plans and profiles, installing and testing water and sewer lines,
performing compaction and trench safety, restoring pavement and surfaces, and managing traffic control and
erosion control measures. Questions simulate realistic field and office scenarios to test critical thinking, code
application, and professional judgment. The format consists of 100 original multiple-choice questions that mirror
the cognitive demands, style, and difficulty distribution of the live proctored examination.
SECTION ONE
Question 1
According to Wisconsin Administrative Code, a Utility Contractor license is required for any person who:
A. Installs landscaping around a building
B. Installs, connects, or repairs underground sanitary sewers, water mains, or storm sewers connected to a public
system
C. Performs interior plumbing within a single-family home
D. Operates a backhoe for snow removal
🟢 Correct Answer: B
🔴 RATIONALE: SPS 305 specifically regulates the construction of public and private utility systems that connect
to the public infrastructure, requiring a certified utility contractor for such work.
,Question 2
A contractor is installing a sanitary sewer main. The pipe material is PVC SDR 35. What type of joint is typically
used?
A. Welded joint
B. Bell and spigot with an elastomeric gasket
C. Flanged joint with bolts
D. Solvent-cemented joint
🟢 Correct Answer: B
🔴 RATIONALE: SDR 35 PVC sewer pipe uses an integral bell and a rubber gasket (push-on joint) designed to
provide a watertight seal while accommodating slight ground movement.
Question 3
What is the minimum slope for a 6-inch diameter sanitary sewer lateral per standard Wisconsin plumbing and
sewer codes?
A. 1/16 inch per foot
B. 1/8 inch per foot
C. 1/4 inch per foot
D. 1/2 inch per foot
, 🟢 Correct Answer: C
🔴 RATIONALE: To achieve a self-scouring velocity of 2 feet per second, smaller-diameter pipes require a
steeper slope. 6-inch sewer laterals typically require a minimum 1/4 inch per foot.
Question 4
In trench safety, what is the primary function of a "Trench Box" (trench shield)?
A. To pump water out of the trench
B. To protect workers from cave-ins by providing a rigid, protective enclosure
C. To guide the excavator bucket
D. To compact the bedding material
🟢 Correct Answer: B
🔴 RATIONALE: A trench shield is a protective system that is dragged along the trench. It is not designed to
prevent cave-ins (shoring does that) but to protect workers if a cave-in occurs.
Question 5
When performing a hydrostatic pressure test on a newly installed water main, the test pressure is typically:
