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.
As shown in Figure 8, a drainage system has three components: . A field drainage system, which prevents ponding water on the field and/or controls the. water table. . A main drainage system, which conveys the water away from the farm. . An outlet, which is the point where the drainage water is led out of the area. The field drainage system is a network that gathers the excess water from the land by. means of field drains, possibly supplemented by measures to promote the flow of water to. these drains.
