In a few weeks I will be installing a septic system (done it) and a leech field (done it), but am unsure of the materials needed. In the past the material was bought and on site for me to install. I have done a fair amount of research in the installation of a leech field, proper care and maintenance of the entire septic system but continue to struggle to find any kind of parts list to build a leech field. I want to add that due to cost, an “infiltrator” system is out. Any input that anyone with experience in this arena would be greatly appreciated.
