The North Carolina Water Purification and Sewage Disposal Contractor examination covers safety, shotcrete, concrete, concrete reinforcement, excavation and grading, water regulations, contractor laws, liens, utility-location requirements, erosion and sedimentation control, and formwork. Candidates need a broad understanding of construction work associated with water and wastewater treatment facilities while also knowing how to locate exact information in the references approved for examination-room use.

The two exam-room-approved rental books included in this package are the North Carolina Occupational Safety and Health Standards for the Construction Industry, with the latest available amendments, and North Carolina Administrative Code Title 15A Subchapter 18C: Water Supplies, including the latest amendments. These references may be used during the open-book examination in accordance with the testing center’s reference-material rules.

The package also includes ten professionally highlighted and tabbed study-only books. These additional references provide preparation in excavation safety, contractor business and project management, erosion control, concrete materials, shotcrete, reinforcing-bar placement, formwork, North Carolina licensing laws, and related construction practices. The study-only books are not allowed inside the examination room.

The included trade self-study course provides 6 months of course access. Candidates can review each examination category, strengthen technical knowledge with the complete rental library, and complete timed reference-navigation exercises using the two books permitted inside the testing center.

Please allow 15 business days for professional highlighting and tabbing before shipment. The package price is $1,590, plus a refundable $700 rental-book deposit, for a total initial payment of $2,290. The $700 deposit is refundable when the complete twelve-book rental set is returned in similar condition within six months from the date the books are received.

Open Book Test

The North Carolina Water Purification and Sewage Disposal Contractor examination is an open-book test. Only the two references identified in the Exam Room Approved Books section are included for use inside the examination center. The ten additional rental books are study-only references and are not permitted inside the examination room.

The North Carolina Occupational Safety and Health Standards for the Construction Industry supports questions involving excavation, trenching, access, spoil placement, concrete construction, reinforcing steel, formwork, scaffolds, ladders, cranes, rigging, personal protective equipment, electrical hazards, tools, and material handling.

North Carolina Administrative Code Title 15A Subchapter 18C: Water Supplies supports questions involving public water-supply requirements, definitions, construction standards, treatment facilities, distribution considerations, approvals, operations, and regulatory responsibilities.

The ten study-only books are intended to build technical and regulatory knowledge during preparation. They should be used throughout the six-month course period, but timed exam-room navigation drills should be completed using only the two approved references.

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

References must be complete and securely bound. Loose papers and attached supplemental materials are not permitted. Candidates may not write in the references before or during the examination session under the published testing rules.

The 120-minute testing period provides an average of two minutes and twenty-four seconds per question. Candidates should learn the main construction principles before test day and use the approved books when a question requires an exact safety provision, regulatory requirement, definition, or technical standard.

Licensing Steps

1. Select the Water Purification and Sewage Disposal classification. Confirm that the classification matches the water-treatment, wastewater-treatment, and related construction work the business plans to perform.
2. Choose the applicable license limitation. Select a limitation that corresponds with the applicant’s financial qualifications and expected project values.
3. Identify the qualifier. Designate the individual whose accepted examination will support the requested classification.
4. Gather the required application information. Organize the business, ownership, qualifier, financial, and background information required for the filing.
5. Submit the applicable materials. Complete the current application or examination-request process established by the North Carolina Licensing Board for General Contractors.
6. Receive examination eligibility. Eligible candidates receive instructions for registering and scheduling the examination through PSI.
7. Begin the trade self-study course. Use the six-month course-access period to review concrete, reinforcement, shotcrete, excavation, safety, water regulations, formwork, erosion control, laws, and utility-location topics.
8. Study the complete rental set. Use all twelve highlighted and tabbed books to strengthen technical and regulatory knowledge.
9. Practice approved-reference navigation. Complete timed exercises using only the two references allowed inside the examination room.
10. Schedule and take the examination. Bring the required identification and only the approved exam-room books.
11. Complete remaining licensing requirements. Passing the examination satisfies the testing requirement, but the licensing board must approve the complete application before issuing a license.
12. Return the complete rental set. Return all twelve books in similar condition within six months from the date received to qualify for the refundable $700 deposit.

Passing the examination does not independently authorize an individual or business to perform licensed contracting work. The approved applicant or business entity must receive and maintain the appropriate North Carolina contractor license.

State Requirements

The North Carolina Water Purification and Sewage Disposal classification covers construction work on 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 the construction of treatment facilities.

The classification includes covered work associated with concrete construction, insulation, interior construction, masonry construction, roofing, and metal erection when that work is performed as part of a water or wastewater treatment facility project.

Typical work may involve treatment structures, tanks, process buildings, concrete basins, foundations, equipment pads, piping-related construction, excavation, grading, reinforcing steel, formwork, shotcrete, site improvements, and supporting structures.

The contractor classification determines the type of construction work the licensed business may perform. The license limitation determines the monetary value of individual projects the contractor may undertake. Applicants should select both according to the company’s intended services, financial qualifications, and expected project values.

The applicant must designate a qualifier whose accepted examination supports the Water Purification and Sewage Disposal classification. The qualifier demonstrates examination knowledge, while the contractor license is issued to the approved applicant or business entity.

North Carolina generally requires a general contractor license when a person or business undertakes covered construction work valued at $40,000 or more. The licensed entity must hold a classification appropriate for the work and a limitation that permits the project value.

Contractors must also comply with applicable permits, approved plans, inspections, environmental rules, water-supply regulations, erosion and sedimentation-control requirements, utility-location procedures, workplace-safety standards, and project-specific technical specifications.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep supports students through organized study guidance, trade-focused review, practice-oriented preparation, reference navigation, and a confidence-building study structure. This package combines a twelve-book rental library with a self-study course designed around the North Carolina Water Purification and Sewage Disposal Contractor examination.

The professionally highlighted and tabbed books reduce the work involved in developing an organized study system. Highlighting directs attention to important water regulations, safety provisions, concrete methods, reinforcing-steel practices, shotcrete procedures, formwork topics, erosion-control rules, utility-location guidance, business requirements, and contractor regulations.

The separation between exam-room-approved and study-only books helps candidates prepare with the correct expectations. Students can use the complete twelve-book library during the course while reserving timed exam-navigation practice for the two references permitted inside the testing center.

The six-month course period gives candidates time to review lessons, revisit challenging subjects, and become familiar with the organization of the approved books. Consistent practice can improve confidence when locating exact information under timed conditions.

No course or rental-book package guarantees a passing score, examination eligibility, licensing approval, or a specific outcome. Results depend on the candidate’s qualifications, knowledge, practical experience, preparation, reference familiarity, and examination performance.
