Drainfields, also called leach fields, absorption beds, soil absorption systems, and leaching beds, perform the functions of septic effluent treatment and disposal in onsite wastewater treatment systems, conventionally called "septic systems".
We discuss several different conventional soil absorption systems: absorption fields: conventional trench, deep trench, shallow trench, cut-and-fill, and gravelless septic systems. Then we discuss septic absorption beds, and seepage pits. Basic septic system designs are discussed beginning at SEPTIC SYSTEM DESIGN BASICS. Advanced & alternative septic treatment methods are discussed beginning at SEPTIC SYSTEM DESIGN ALTERNATIVES.
Once we know the total area of effluent disposal system needed, such as length in feet of gravel-filled perorated pipe trenches (or galleys or gravelless or whatever) then the septic system installer will excavate to prepare the drainfield in a pattern or shape that divides that length into sub-lengths of parallel (or other) trenches or pits or whatever, and the location, routing, etc. of these will be determined by the lot size and shape so that the necessary septic system components fit AND are separated by the reacquired distances from one another and from site boundaries and other site features like the well or buildings, driveways, and the like.
The specific shape and dimensions for a specific property, soil characteristics, and septic system type can't really be specified precisely here since we know the detailed answers to the septic system drainfield design considerations listed above. But we have posted addition articles on septic system drainfield design that give the general septic system specifications that should be helpful.
