North Carolina Water Purification and Sewage Disposal Contractor Books & Course Rental - Exam Room Approved

Prepare for the North Carolina Water Purification and Sewage Disposal Contractor examination with a focused rental package that combines both exam-room-approved references with a structured self-study trade course. Each rental reference is professionally highlighted and tabbed to support organized preparation, efficient information searches, and practical use during the open-book examination.

The North Carolina Water Purification and Sewage Disposal Contractor exam covers water and wastewater treatment construction, workplace safety, concrete, concrete reinforcement, shotcrete, formwork, excavation, grading, water-supply regulations, utility-location requirements, erosion control, contractor laws, and liens. Candidates need a broad understanding of construction practices while also knowing how to locate exact safety standards and water-supply regulations in the approved books.

This package includes 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. Both references are approved for use inside the North Carolina Water Purification and Sewage Disposal Contractor examination room.

Each rental reference is professionally highlighted and tabbed. Highlighting directs attention to important definitions, safety requirements, excavation provisions, protective systems, concrete-related rules, water-supply regulations, permitting provisions, treatment requirements, monitoring standards, reporting responsibilities, and other topics that may support examination preparation. Permanent tabs create practical access points so students can become familiar with the organization of each reference before test day.

The included trade self-study course provides 6 months of course access. Students can review the examination subjects at their own pace, revisit difficult lessons, and practice locating information in the same highlighted and tabbed references they plan to take into the testing center.

Please allow 15 business days for professional highlighting and tabbing before shipment. The package price is $420, plus a refundable $100 rental-book deposit, for a total initial payment of $520. The $100 deposit is refundable when all rental books are returned within six months in similar condition.

Open Book Test

The North Carolina Water Purification and Sewage Disposal Contractor examination is an open-book test. The two highlighted and tabbed rental references included in this package are approved for use inside the examination room.

The North Carolina Occupational Safety and Health Standards for the Construction Industry supports questions involving excavation, trench protection, personal protective equipment, concrete operations, formwork, reinforcing steel, equipment, ladders, scaffolds, fall protection, material handling, cranes, rigging, electrical hazards, and other construction-site safety requirements.

North Carolina Administrative Code Title 15A Subchapter 18C: Water Supplies supports questions involving public water-supply requirements, system construction, treatment, operation, monitoring, reporting, permitting, public-health protections, and administrative responsibilities.

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

Loose papers and attached supplemental materials are not permitted. References may not contain prohibited handwritten notes, and candidates may not write in the books during the examination. Downloaded code material must be complete and securely bound. Partial references are not accepted for testing.

The 120-minute examination period provides an average of approximately two minutes and twenty-four seconds per question. Candidates should understand the major trade principles before test day and use the approved references when a question requires an exact regulatory provision, safety rule, definition, table, or procedural requirement.

Effective open-book preparation involves more than bringing books into the testing center. Candidates should practice identifying a question’s subject, choosing the correct reference, moving to the appropriate tab, and confirming the answer without reading large portions of unrelated material.

Licensing Steps

1. Select the Water Purification and Sewage Disposal classification. Confirm that the classification matches the water and wastewater treatment work the business intends to perform.
2. Choose the appropriate license limitation. Select the limitation that fits the applicant’s financial qualifications and anticipated project values.
3. Identify the qualifier. Designate the individual whose accepted examination will support the requested classification.
4. Prepare the licensing application. Assemble the required business, ownership, qualifier, financial, and background information.
5. Submit the required materials. Complete the current application or examination-request process established by the North Carolina Licensing Board for General Contractors.
6. Receive examination eligibility. Approved candidates receive an eligibility letter and instructions for registering and scheduling through PSI.
7. Begin the self-study course. Use the six-month access period to review concrete, shotcrete, reinforcement, formwork, excavation, safety, and water regulations.
8. Practice with the rental references. Work with the highlighted and tabbed materials regularly so their organization becomes familiar before test day.
9. Schedule and take the examination. Bring the required identification and both approved rental references in acceptable condition.
10. Complete the remaining licensing requirements. Passing the examination satisfies the testing component, but the licensing board must approve the complete application before issuing the license.
11. Return all rental books. Return both rental references within six months in similar condition to qualify for the refundable $100 deposit.

Passing the examination does not independently authorize a person or company to perform licensed contracting work. The applicant or business entity must receive and maintain the applicable North Carolina general contractor license.

State Requirements

The North Carolina Water Purification and Sewage Disposal classification covers demolition and construction work involving water and wastewater systems and water and wastewater treatment facilities.

The classification also covers site work, grading, and paving of parking lots, driveways, sidewalks, curbs, and gutters when that work is ancillary to the construction of water and wastewater treatment facilities.

As part of work on qualifying treatment facilities, the classification includes work performed under several specialty classifications. These areas include concrete construction, insulation, interior construction, masonry construction, roofing, and metal erection.

Projects may involve treatment structures, basins, tanks, equipment foundations, process areas, piping-related structures, site grading, access improvements, reinforced concrete, structural components, and supporting construction associated with water or wastewater treatment facilities.

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

North Carolina generally requires a general contractor license when the total value of a covered construction project is $40,000 or more. The licensed entity must hold the appropriate classification and a license limitation that permits the value of the project being undertaken.

The classification identifies the type of contracting work the license holder may perform. The limitation determines the monetary value of individual projects the contractor may undertake. Applicants should select both according to their planned services, financial qualifications, and anticipated contract sizes.

Reference Books

This package includes two professionally highlighted and tabbed rental references. Both books are approved for use inside the North Carolina Water Purification and Sewage Disposal Contractor examination room.

• Included Rental Book: North Carolina Occupational Safety and Health Standards for the Construction Industry, with Latest Available Amendments
  This reference contains construction safety requirements involving excavations, trench protection, concrete operations, reinforcing steel, formwork, equipment, fall protection, ladders, scaffolds, material handling, cranes, rigging, personal protective equipment, and other jobsite hazards.

Candidates should practice with both approved references before test day. Highlighting and permanent tabs create an organized navigation system, but repeated use is necessary to become familiar with each book’s structure, terminology, sections, and regulatory organization.

Test Information and Study Materials

The included self-study trade course provides 6 months of course access. It organizes the examination subjects into practical study areas and helps candidates combine construction knowledge with repeated reference-navigation practice.

Begin with concrete because it is the largest individual content category. Review concrete materials, batching concepts, placement, consolidation, finishing, curing, joints, weather considerations, testing principles, common defects, and safe work practices.

Concrete reinforcement preparation should include reinforcing-bar identification, handling, storage, placement, spacing, supports, ties, splices, clear cover, embedments, tolerances, and coordination with formwork and concrete placement.

Formwork study should address materials, layout, supports, bracing, ties, shores, reshoring concepts, pressure, stability, inspection, stripping, and safety. Candidates should understand the relationship between formwork, reinforcement, embeds, and concrete-placement procedures.

Shotcrete preparation should include materials, equipment, application methods, surface preparation, reinforcement, nozzle operation, placement, rebound, curing, testing concepts, and repair considerations.

Excavation and grading review should cover soil conditions, trench geometry, protective systems, sloping, benching, shielding, shoring, dewatering, access, spoil placement, grade control, backfill, compaction, and equipment safety.

Water-regulation study should focus on navigating Title 15A Subchapter 18C. Practice locating definitions, system requirements, construction provisions, treatment rules, monitoring responsibilities, reporting requirements, and administrative procedures.

Timed drills should be included throughout preparation. Read a question, identify its subject, decide whether the safety standards or water-supply regulations apply, locate the relevant tab, and confirm the answer from the applicable section.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep supports candidates through organized study guidance, trade-focused review, practice-oriented preparation, reference navigation, and a confidence-building study structure. This package combines both approved examination references with a self-study Water Purification and Sewage Disposal Contractor course.

The professionally highlighted and tabbed rental books reduce the time required to build a reference-navigation system. Highlighting directs attention to important safety standards, water-supply regulations, definitions, procedures, and administrative provisions. Permanent tabs create practical access points for repeated practice.

The self-study course helps candidates review concrete, reinforcement, shotcrete, formwork, excavation, grading, safety, water regulations, utility-location requirements, erosion control, laws, and liens. Students can work through the lessons at their own pace and revisit difficult subjects throughout the six-month access period.

The rental period allows candidates to prepare with the same books they plan to use during the examination. Regular practice can strengthen familiarity with the tabs, section organization, regulatory terminology, and location of frequently reviewed information.

No course or rental package guarantees a passing score, license approval, or a specific examination result. Performance depends on the candidate’s knowledge, practical experience, preparation, reference familiarity, and decisions during the test.
