Drain Field Installation 101

Septic systems play a crucial role in managing wastewater for properties that lack a connection to a municipal sewer line. The drain field holds a pivotal position among the essential components of a septic system. Proper drain field installation is essential for efficient and environmentally sound effluent treatment. As a reputable septic company, Rooter Man recommends these three critical factors you need to know about drain field installation.


The Right Size Matters

In drain field installation, size matters more than you might realize. The size of the drain field is determined by the property’s water usage, the number of occupants, and the soil’s permeability. The primary purpose of the drain field is to allow effluent (treated wastewater) to gradually seep into the soil, where further natural filtration and purification occur.

Undersized drain fields can overload the soil’s capacity to absorb and treat the wastewater, resulting in potential backups, foul odors, contamination, and costly septic tank repair jobs. In addition, an excessively large drain field may need more water flow for effective treatment. Therefore, it’s imperative to calculate the drain field size accurately based on the property’s specific characteristics and usage patterns. A professional septic company can account for the vital factors, ensuring an efficient and safe waste management system. 

Understanding Soil Permeability

Soil permeability refers to how quickly the soil can absorb water. It is a critical factor in septic tank installation, as different soils have varying permeability levels. A percolation test, or a "perc test," assesses the soil’s ability to absorb water.

During a perc test, we dig a series of holes in the proposed drain field area and pour water into the holes. The rate at which the water drains into the soil helps determine whether the soil can adequately handle the effluent from the septic system. If the soil doesn’t absorb water quickly enough, modifications to the drain field design may be necessary to ensure proper wastewater treatment. The last thing is a flooded yard because of improper septic tank installation. 

Strategic Location Selection

The location of the drain field on the property is a decision that should be taken with seriousness. Several factors must be considered when selecting the ideal location for drain field installation. It should be situated away from contamination sources, such as wells, bodies of water, and property lines. In addition, the drain field should not be placed in areas prone to flooding or areas with heavy foot or vehicle traffic to minimize damage and costly septic tank repair emergencies. 

The drain field’s proximity to the septic tank matters. The effluent that leaves the septic tank must travel to the drain field pipes, and excessive distance or obstacles between the two components can hinder the natural flow of wastewater. Professional septic tank experts possess the expertise to determine the optimal location to ensure efficient wastewater treatment and minimize environmental impact.

Drain field installation is a critical aspect of septic system setup for properties without access to a sewer line. Understanding the significance of size, soil permeability, and strategic location selection is essential for a successful installation process. Property owners should work closely with experienced professionals who can conduct accurate assessments, perform necessary tests, customize drain field designs, and schedule routine septic tank pumping and maintenance.

By adhering to proper drain field installation guidelines, you can ensure the longevity and effectiveness of your septic system, contributing to environmental preservation and a well-functioning wastewater management solution.
