What type of documentation must an installer provide after completing an OSSF installation?

After completing an OSSF installation, it is critical for the installer to provide as-built drawings and maintenance instructions. As-built drawings document the exact specifications and location of the installed system, which aids in future maintenance, potential repairs, and any necessary improvements. This detailed documentation reflects any changes made during the installation process compared to the original design.

Additionally, maintenance instructions are essential for the property owner to understand how to properly care for and operate the system. These instructions can help prevent misuse or neglect that could lead to system failure or contamination issues. Providing both as-built drawings and maintenance instructions ensures that the installer complies with regulations while also supporting the longevity and efficiency of the OSSF.
