How Does A CONVENTIONAL Leach Line Work?

The leach line, also referred to as a drain field or disposal area, takes the relatively “solids” free water called effluent from the septic tank and distributes it into the soil for final impurity and contaminate removal. Leach lines are generally constructed of perforated pipe installed at the upper part of a gravel filled trench. They come in many different configurations, lengths and depths. Your local governing entity will determine the appropriate size according to the soils composition.

JT's Septic does not do leach line repair at this time. Please contact a company on our referral list for leach line repairs. 

cesspool

Excavations that receive untreated sanitary waste containing human excreta, which sometimes has an open bottom and/or perforated sides (40 CFR 144.3). Cesspools are essentially outhouses with running water. Since there is little or no treatment, cesspools can contaminate groundwater. Also, often times cesspools have no lids covering the opening creating a safety hazard. Cesspools are no longer recognized as transferable systems in the state of Arizona (as of 1976).

ALTERNATIVE DISPOSAL AREAS

A wastewater treatment system that includes components different from those typically used in a conventional septic tank and subsurface wastewater infiltration system (SWIS). An alternative system is used to achieve acceptable treatment and dispersal of wastewater where conventional systems either might not be capable of protecting public health and water quality or are inappropriate for properties with shallow soils over ground water or bedrock or soils with low permeability. Examples of components that can be used in alternative systems are sand filters, aerobic treatment units, disinfection devices, and alternative subsurface infiltration designs such as mounds, gravelless trenches, and pressure and drip distribution. The most common alternative systems in the Prescott area are:

Aerobic Treatment UnitA mechanical wastewater treatment unit that provides secondary wastewater treatment for a single home, a cluster of homes, or a commercial establishment by mixing air (oxygen) and aerobic and facultative microbes with the wastewater. ATUs typically use a suspended growth process (such as activated sludge-extended aeration and batch reactors), a fixed-film process (similar to a trickling filter), or a combination of the two treatment processes.

While conventional systems rely on a single biomat forming at the soil interface, the Eljen GSF adds a second, primary biomat layer on the surface of it's unique Bio-Matt™ Fabric.

Sand Filter: A packed-bed filter of sand or other granular materials used to provide advanced secondary treatment of settled wastewater or septic tank effluent.
