Open Book Test

The North Carolina Water Purification and Sewage Disposal Contractor examination is an open-book test. Candidates may use only the references approved for this classification. This package includes two exam-room-approved books and ten additional references that are provided for study only.

The approved books are the North Carolina Occupational Safety and Health Standards for the Construction Industry and North Carolina Administrative Code Title 15A Subchapter 18C: Water Supplies. The other ten books contain important examination material but are not allowed inside the testing room.

Approved references may be highlighted, underlined, and indexed before the examination. Tabs must be permanent and securely attached to the pages. Removable index flags, temporary tabs, and Post-it-style markers are not accepted. Notes may not be written on the tabs.

Loose papers and attached supplemental materials are not permitted. Candidates may not write in their books during the examination session. Printed regulations should be complete and properly bound when presented for inspection at the testing center.

The 120-minute testing period provides an average of approximately two minutes and twenty-four seconds per question. Candidates should practice identifying the subject, choosing the correct reference, locating the applicable tab, and confirming the answer without spending unnecessary time searching.

Licensing Steps

1. Select the Water Purification and Sewage Disposal classification. Confirm that the classification matches the water and wastewater treatment construction work the business intends to perform.
2. Choose the appropriate license limitation. Select the limitation that fits the company’s financial qualifications and anticipated project values.
3. Establish the business entity. Form the LLC or corporation under which the contracting business will operate.
4. Obtain the EIN. Complete the IRS filing used for business banking, tax administration, payroll, and employee hiring.
5. Identify the qualifier. Designate the individual whose accepted examination will qualify the company for the requested classification.
6. Prepare the licensing application. Assemble the required ownership, qualifier, business, financial, and background information.
7. Use the included Application Service. Receive assistance organizing the applicable application information and supporting documents.
8. Receive examination eligibility. After approval, follow the instructions provided for registering and scheduling the examination with PSI.
9. Take the examination. Bring the required identification and only the approved references that comply with testing-center rules.
10. Complete the licensing process. Satisfy the remaining board requirements before the license is issued.
11. Maintain contractor compliance. Keep the business entity, licensing records, renewals, tax information, and required filings properly organized.

Passing the examination completes the testing portion of the process but does not independently issue a contractor license. The applicant and business entity must satisfy the applicable requirements of the North Carolina Licensing Board for General Contractors.

State Requirements

North Carolina generally requires a general contractor license when the total value of a covered construction project is $40,000 or more. The contractor must hold a classification and limitation appropriate for the type of work and the value of the project.

The Water Purification and Sewage Disposal specialty classification covers construction related to water and wastewater systems and water and wastewater treatment facilities. It also includes site work, grading, and paving of parking lots, driveways, sidewalks, curbs, and gutters when those activities are ancillary to construction of a covered treatment facility.

The classification also includes certain specialty work performed as part of water and wastewater treatment facility construction, including concrete construction, insulation, interior construction, masonry construction, roofing, and metal erection. This broad scope is reflected in the examination’s emphasis on concrete, reinforcing steel, shotcrete, formwork, excavation, safety, and water-supply regulations.

The applicant must designate a qualifier whose accepted examination supports the requested classification. The classification identifies the type of contracting work the licensed business may perform, while the license limitation governs the monetary value of projects the contractor may undertake.

Business formation creates the legal LLC or corporation under which the contractor operates. EIN filing provides the federal identification number commonly used for banking, tax management, payroll, and employee-related activities. These services are included to help establish an organized business foundation.

Test Information and Study Materials

The included trade course provides 1 year of self-study access and live-class instruction. Candidates can use the self-study component to review subjects repeatedly and attend the live class for guided preparation across the examination categories.

Begin with concrete, reinforcement, and formwork because these subjects account for 21 of the 50 questions. Review concrete materials, mixture properties, placement, consolidation, finishing, curing, bar identification, spacing, supports, clearances, splices, form loads, pressures, bracing, shores, and stripping procedures.

Shotcrete accounts for five questions. Study dry-mix and wet-mix processes, delivery equipment, surface preparation, reinforcement, nozzle operation, rebound, construction joints, curing, inspection, and quality-control practices.

Excavation and grading account for seven questions. Review soil conditions, trenches, slopes, protective systems, access, spoil placement, dewatering, equipment, backfill, compaction, and underground utility precautions. Connect these topics with the approved occupational safety standards.

Water regulations represent a smaller category, but exact regulatory language may be important. Practice navigating Title 15A Subchapter 18C and locating definitions, construction provisions, treatment-related requirements, system standards, and administrative responsibilities.

One Call and erosion-control subjects must be studied before the examination because their primary references are not allowed in the testing room. Review excavation notifications, utility markings, tolerance-zone awareness, land-disturbing activities, stabilization, sediment-control measures, inspections, and contractor obligations.

Use timed reference exercises throughout the course. Identify the question topic, choose the correct approved reference, locate the applicable tab, and confirm the answer from the relevant passage or table. Repeated practice helps candidates develop both technical knowledge and efficient navigation habits.
