An engineered septic system is designed based on the native soil’s ability to drain. A “Perc Test” (percolation test) measures how quickly water drains into the soil, providing critical data for designing your septic system. Proper testing helps determine the size and type of drainage system, ensuring your system will function optimally. The following video is a very informative piece about perc tests and engineered septic systems.

WHAT IS AN ENGINEERED SEPTIC SYSTEM?
An engineered septic system is designed to solve specific septic challenges. Some properties have limited space, poor-draining soil, or high groundwater levels, all of which can cause septic issues if the system is not properly customized. An engineered septic system accounts for these factors, ensuring that it functions effectively for many years. At Big Bore Drilling, we work closely with local engineers who have successfully designed numerous septic systems for our customers in Fresno and Madera Counites. We’re happy to refer you to an expert for your septic project.
Soil Types and Septic System Performance
Different soil types drain at varying rates. The porosity and permeability of the soil play critical roles in determining how quickly water can move through it. Porosity refers to the amount of open space within soil or rock, indicating how much fluid it can hold. These spaces may exist between grains or within cracks and cavities. Permeability measures how easily a fluid, like water, can flow through the porous material used in the leach field. Understanding these factors is essential in designing a system that works efficiently on your property.
WHAT IS A "PERC TEST"?
ENGINEERED SEPTIC SYSTEM SQUIRT TEST
This test shows how a raised mound leach bed works. A pump installed in the septic tank filters and pumps effluent water to the leach bed. After the squirt test is complete, orifice shields are added to block the water stream, which then trickles gently through the leach bed. The bed will later be covered by a raised dirt mound. The video below provides a clear demonstration of this squirt test and how the raised mound leach bed functions.
ROCK Filled LEACH BED TESTING
Here's an example of an engineered leach bed. A pump with a filter is installed in the septic tank, which pumps the effluent water up to a distribution box. From there, water flows evenly through 4-inch pipes into the rock-filled leach bed. Black filter fabric covers the rock to prevent soil from contaminating the clean gravel and ensuring proper drainage.
