The reason newly constructed collection system sewers should be inspected is to:

The primary reason for inspecting newly constructed collection system sewers is to ensure that the contractor has complied with the plans and specifications outlined in the project documentation. This compliance check helps verify that the construction meets the established engineering standards, design criteria, and regulatory requirements, which are crucial for the system's functionality and longevity. By conducting inspections, utilities can identify any deviations from the planned work, ensuring that the sewer operates effectively and minimizes the risk of future issues such as blockages or structural failures.

While other alternatives, such as assessing the success of smoke or dye tests and checking street pavement, may be relevant to the overall project management, they do not directly relate to the primary purpose of inspecting newly constructed sewers. Therefore, compliance inspections serve as a foundational quality control measure in the construction process.
