Drain Field

Definition

A system of trenches filled with sand, gravel, or crushed stone, and a series of pipes to distribute septic tank effluent into the surrounding soil.

Purpose

The drain field, or leach field, is a critical component of a septic system. It treats and disperses wastewater from the septic tank into the soil, where natural processes filter out contaminants, preventing pollution and protecting groundwater.

Examples of Use

1. Residential Septic Systems: Used in homes not connected to municipal sewage systems to treat and disperse wastewater.
2. Rural Properties: Essential for properties with on-site septic systems, providing an environmentally friendly wastewater treatment solution.
3. Small Communities: Some small communities use shared drain fields as part of their wastewater management systems.

Related Terms

• Septic Tank: A tank that collects and partially treats wastewater from a household.
• Effluent: Treated wastewater that flows out of a septic tank or sewage treatment plant.
• Leach Field: Another term for a drain field, describing the area where effluent is dispersed.

Notes

• Proper design and maintenance of a drain field are essential to prevent system failure and environmental contamination.
• Periodic inspection and pumping of the septic tank help ensure the longevity and effectiveness of the drain field.
