Here’s how a Title 5 septic leaching system is built: dig deep holes or trenches, to way below most roots, earthworms and oxygen, 5-10′ deep (sometimes even deeper) – way below most roots, earthworms and oxygen that are needed in order to get sufficient treatment of the sewage effluent – put in gravel or plastic tunnels, and perforated pipes, and then fill up with sand.
