Can I install my own OWTS?

Maybe. Determining whether you can install a system depends on many factors. First, alternative systems, as determined by soil morphology, must be designed by a professional engineer and installed by a licensed OWTS installer. Soils suitable for a conventional system, as determined by soil morphology, may be installed by an owner/occupant of a residential property provided a level of competency is present (determined by testing or interviewing as necessary) and at the sole discretion of the Building Official.
