Septic Leach Field Design

Drain fields can consist of four sections 25 feet long or two sections 50 feet long.

Septic leach field design. If placed in an area with good ground absorption a drain field can last up to 10 years. A leach field can be under a road. When you design your drain field there are a few things to keep in mind. The most common reasons for leach field failure are.

Septic tanks last from 15 to 30 years. Trying to use a single compartment septic tank absence of a particulate filter under sized leach field and lack of leach field ventilation. A high quality septic drainfield or leach bed design includes inspection ports or pipes that permit inspection of the condition of the field. Step 1 determine the size.

A septic drain field is a vital part of any septic system. 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 size necessary for your drain field will depend on a few. Organic materials in the liquid are catabolized by a microbial ecosystem.

Septic tank design is a science. Oxygen is very important to leach field health and a drywell with surface vent at end of lateral line is an instant fix for that while greatly increasing the capacity and drying out the lateral lines. Unfortunately drain fields also known as leach fields do not last that long. An improperly designed drain field will do nothing but cause huge problems with the entire system.

Professional septic tank designers are trained to know exactly what type of system to put in for each location.
