This however is not true.
Septic tank and leach field.
One a septic system is approved engineers run 3 or 4 inch perforated drain pipe through the leach field at an appropriate depth for the soil conditions.
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.
The pipes are surrounded by aggregate that.
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.
Organic materials in the liquid are catabolized by a microbial ecosystem.
Septic tank and septic drain field 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.
The main purpose of the leach field is to disperse liquids from the septic tank in the an area of soil by means of drains which eventually gets spread out in the large area known as the leach field.
The most common cause of septic system problems and failure is their septic system absorption component more commonly known as a drainfield becoming.
Unfortunately drain fields also known as leach fields do not last that long.
Many people with septic system problems such as odor slow draining sinks and tubs gurgling pipes backups and sewage water ponding in their yard mistakenly assume the cause of these issues is their septic tank.
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.
If placed in an area with good ground absorption a drain field can last up to 10 years.
Drain fields can consist of four sections 25 feet long or two sections 50 feet long.
Septic tanks last from 15 to 30 years.
