Large-capacity cesspools are also Class V wells, but they are banned in Arkansas under authority of the ADH. There are approximately 136 Class V wells that are permitted by ADEQ and 74 bromine wells permitted by AOGC (Linda Hanson, Arkansas Department of Environmental Quality, oral commun., 2013; Rex Robertson, Arkansas Oil and Gas Commission ...
A septic drain field, a septic tank, and associated piping compose a septic system. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals (and surface runoff) from reaching the wastewater distributed within those trenches. [1]
A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]
The mound system was designed in the 1930s by the North Dakota College of Agriculture. [1] and was known as the Nodak Disposal System.In 1976, the University of Wisconsin studied the design of mound systems as part of the university's Waste Management Project.
In Dubrovnik, then known as Ragusa (Latin name), the Statute of 1272 set out the parameters for the construction of septic tanks and channels for the removal of dirty water. Throughout the 14th and 15th century the sewage system was built, and it is still operational today, with minor changes and repairs done in recent centuries. [70]

The aeration stage and the disinfecting stage are the primary differences from a traditional septic system; in fact, an aerobic treatment system can be used as a secondary treatment for septic tank effluent. [1] These stages increase the initial cost of the aerobic system, and also the maintenance requirements over the passive septic system.
