Layout Septic System Leach Field Design

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

Layout septic system leach field design.

Chamber systems are a tried and true advancement in leach field design arched panels in the trench. A high quality septic drainfield or leach bed design includes inspection ports or pipes that permit inspection of the condition of the field. While all septic tank drain fields require regular inspection you can save a lot of money by digging one yourself. Vertical pipes are placed usually at the end of each drainfield trench or section or at critical or suspect areas near the drainfield to permit monitoring of liquid levels in the drainfield trenches.

An improperly designed drain field will do nothing but cause huge problems with the entire system. This system also uses two tanks and creates a chamber filled with sand and fabric filters to filter waste water which is then pumped into a more traditional leach field. The drain field also called the leach field performs more than half the job in a conventional residential septic system. If you have a septic tank on your property you will need a septic tank drain field also known as a leach field or leach drain to complete the system and make it functional.

Effluent flows into this large open area underneath the yard. A septic drain field is a vital part of any septic system. Unfortunately drain fields also known as leach fields do not last that long.

The entire bottom of a chamber is open. Prepare and design your system. The soil should. Step 1 determine the size.

This pre treats waste water before it reaches the ground and protects the ground water from contamination in a traditional leach septic system. With no gravel inside chambers have ample air to help keep the leach field soil aerobic and healthy. The system then can be designed based on the findings of the survey and results of the soil test. Septic tanks last from 15 to 30 years.

If placed in an area with good ground absorption a drain field can last up to 10 years. When you design your drain field there are a few things to keep in mind. Infiltrator is the original and remains by far the most dependable septic leach field chamber system.

Infiltrator quick4 plus series chambers are high density polyethylene arches that interlock to form a continuous drainage area with a much greater storage surge volume than pipe in gravel leach fields. Not all wastewater treatment takes place within the actual septic tank. The size necessary for your drain field will depend on a few factors.
