Septic leach field design.

Use gravity avoid pumping septic tank water up hills. An improperly designed drain field will do nothing but cause huge problems with the entire system. Trying to use a single compartment septic tank absence of a particulate filter under sized leach field and lack of leach field ventilation. When you design your drain field there are a few things to keep in mind.

Step 1 determine the size. A leach field can be under a road. 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 most common reasons for leach field failure are.

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. A septic drain field is a vital part of any septic system. 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.

Professional septic tank designers are trained to know exactly what type of system to put in for each location. Organic materials in the liquid are catabolized by a microbial ecosystem. 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. Septic tank design you need a professional.

The size necessary for your drain field will depend on a few. A high quality septic drainfield or leach bed design includes inspection ports or pipes that permit inspection of the condition of the field.
