Leach Field Installation

The leach field is one of the most important parts of your septic system—and one of the most common to fail if not installed correctly. At Gross Septic Pumping, we install high-functioning, code-compliant leach fields designed to match your soil, property layout, and septic needs.

Leach Field Design Matters

A poorly designed or undersized leach field can lead to system backups, soggy yards, and groundwater contamination. That’s why every leach field we install is based on a detailed understanding of your property’s soil type, water usage, and tank capacity.

Our process includes:

  • Soil percolation testing to evaluate drainage
  • Sizing calculations to handle your household’s wastewater volume
  • Strategic trench layout for even, reliable dispersal
  • Materials built to last in Arizona’s dry, shifting soils

With the right leach field design, your system will treat and release wastewater effectively—protecting your home, yard, and the environment.

Built for Long-Term Performance in Arizona Conditions

Leach fields in Southern Arizona face intense challenges from heat, dry conditions, and clay-heavy soils. Our team has decades of experience working with these variables to ensure each leach field is durable, functional, and set up for long-term success.

We install systems that account for:

  • Compact or poor-draining soils
  • Erosion risks and site slope
  • Root intrusion and natural vegetation interference
  • Rural property access and regulatory compliance

At Gross Septic Pumping, we don’t just install the lines—we install a solution that keeps your septic system functioning properly for years to come.

Reliable Leach Field Installation

Installing a leach field isn’t just a matter of digging trenches—it’s about engineering a system that will properly treat and disperse wastewater for decades. At Gross Septic Pumping, we take a detailed, site-specific approach to every leach field installation to ensure lasting performance and full compliance with local standards.

Here’s what our installation process typically includes:

Site and Soil Evaluation

We begin by performing percolation tests and soil evaluations to determine how well your land absorbs wastewater. This helps us choose the right field size and layout to match your property’s drainage capacity.

Field Sizing and System Design

Your leach field needs to handle your home’s wastewater output without overloading. We calculate line length, spacing, and trench depth based on household size, usage, and tank volume to ensure optimal flow and dispersal.

Trench Excavation and Line Installation

Our team excavates the field using careful grading to prevent pooling or uneven saturation. We install distribution lines with the proper pitch and backfill them with approved materials for both filtration and durability.

Drainage and Soil Compaction Checks

After installation, we ensure water disperses evenly throughout the field and check for any signs of improper drainage or future saturation risks. This step is key to preventing backups and system failure.

Root and Vegetation Planning

Roots are a leading cause of leach field damage. We help identify and mitigate risks from nearby trees and shrubs, and offer solutions like root barriers or relocation advice to extend the life of your field.

Full Code Compliance and Final Testing

We follow all ADEQ and local health department guidelines, complete necessary permits, and perform final system checks to ensure everything is functioning correctly and ready for inspection or use.
