Gravelless septic field designs: this article series discusses the design, product alternatives, life and cost of several types of gravelless or "no gravel" or "no rock" septic drainfield systems, offering installation specifications and a list of product suppliers. Septic drainfields, also called leach fields, absorption beds, soil absorption systems, soakaway beds, and leaching beds, perform the functions of septic effluent treatment and disposal in onsite wastewater treatment systems, conventionally called "septic systems".

Gravelless septic systems or "no gravel" septic system trenches use plastic or other prefabricated wastewater distribution systems which are buried in soil without the use of surrounding gravel.
Typical gravelless septic systems use a plastic chamber, a geotextile-wrapped pipe, or a polystyrene-wrapped pipe to distribute effluent into the soil. The necessary soil absorption area is provided by the perforated surface of the gravelless septic system components (or by soil at the bottom of a chamber) themselves rather than by the gravel and trench walls of a conventional septic drainfield.
Gravelless septic drainfield systems can provide an acceptable effluent disposal system for sites with limited space for a drainfield or where gravel is not available or is quite expensive.
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.

Three Basic No-Rock Gravelless Septic Absorption Field Products / Designs
There are three typical gravel-less effluent disposal systems in current use and shown in the US EPA sketches below (originally from NSFC) and just below we describe a fourth variation which is provided by some manufacturers:
