Septic Tank Drainfield

A septic drain field a septic tank and associated piping compose a septic system.

Septic tank drainfield.

Unfortunately drain fields also known as leach fields do not last that long. A septic leach field also known as a drain field disperses wastewater from your septic tank and removes contaminants before it soaks deeper into the soil. This however is not true. Water saturated drainfield soil absorption area you may need to replace the entire drainfield switch to an alternating bed or set or septic fields or it may be possible to direct surface and subsurface water from other sources away from the drainfield area.

All of the parts of this carefully tuned system must be functioning properly or else the result is a mess and a costly one. Septic tanks last from 15 to 30 years. 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.

Soil based systems discharge the liquid known as effluent. Building a septic drain field is time consuming but pays off in the long run. The solids stay in the tank while the wastewater is discharged to the drainfield for further treatment and dispersal. The most common cause of septic system problems and failure is their septic system absorption component more commonly known as a drainfield becoming.

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. If placed in an area with good ground absorption a drain field can last up to 10 years. The septic tank digests organic matter and separates floatable matter e g oils and grease and solids from the wastewater. 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.

A buried watertight tank designated and constructed to receive and partially treat raw domestic sanitary wastewater. 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. A typical septic system consists of a septic tank and a drainfield or soil absorption field.
