When completing an installer’s affidavit, where should elevations be recorded?

When completing an installer’s affidavit, it is important to record elevations at the beginning, middle, and end of the trench to provide a comprehensive understanding of the site conditions and the proper installation of the septic system. This ensures that the system is installed at the correct depth and slope, which is crucial for effective drainage and operation. By capturing elevations at multiple points along the trench, you can assess variations in the terrain and ensure that the overall system is compliant with design specifications and local regulations. This thorough documentation helps prevent issues related to water flow and system failure, as it allows for a more accurate representation of the installation environment.
