Septic Tank Drainfield

Septic drain fields also called leach fields or leach drains are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank organic materials in the liquid are catabolized by a microbial ecosystem.

Septic tank drainfield.

The solids stay in the tank while the wastewater is discharged to the drainfield for further treatment and dispersal. Unfortunately drain fields also known as leach fields do not last that long. This however is not true. A septic tank consists of one or more concrete or plastic tanks of between 4000 and 7500 litres 1 000 and 2 000 gallons.

It is primarily the drain field pipes that you have to worry about when planting around septic tanks. One end is connected to an inlet wastewater pipe and the other to a septic drain field generally these pipe connections are made with a t pipe allowing liquid to enter and exit without disturbing any crust on the surface. Building a septic drain field is time consuming but pays off in the long run. The septic tank digests organic matter and separates floatable matter e g oils and grease and solids from the wastewater.

You do not want roots penetrating the perforations and gumming up the works. Heavy solids settle to the bottom of the tank while greases and lighter solids float to the top. Over time leach fields can build up sludge or tree roots can grow into them to form clogs which causes your septic tank to back up or leak into your yard. Soil based systems discharge the liquid known as effluent.

A buried watertight tank designated and constructed to receive and partially treat raw domestic sanitary wastewater. All of the parts of this carefully tuned system must be functioning properly or else the result is a mess and a costly one. A septic drain field a septic tank and associated piping compose a septic system. If placed in an area with good ground absorption a drain field can last up to 10 years.

A typical septic system consists of a septic tank and a drainfield or soil absorption field. Septic tanks last from 15 to 30 years. A flooded septic tank that is a tank at abnormally high. The most common cause of septic system problems and failure is their septic system absorption component more commonly known as a drainfield becoming.
