A vampire is a being from folklore who subsists by feeding on the life essence (generally in the form of blood) of the living. In European folklore, vampires were undead beings that often visited loved ones and caused mischief or deaths in the neighbourhoods they inhabited when they were alive.
The Drain or Leach Field consists of a network of perforated pipes (or âlaterals) laid in gravel under the ground that allow the water to pass into the ground from the septic tank. In most systems this pipe consist of PVC or the newer chamber style field lines that have a higher surface area.
Additionally, the pipes that transport the water to the field must be at an appropriate depth. Typical leach field trenches are from 4 to 6 feet deep. The bottom of the trench is filled with gravel or sand to a height of 2 to 3 feet. The minimum depth for leach field pipes is 6 inches.
