Picking the right location for a drain field installation is part art, part science. It requires balancing several factors that impact performance and code compliance. Read on to learn the basics of how our septic company will determine the best location for a drain field installation on your property.
- Slope Matters. Property topography contributes significantly to the placement of the drain field. The ideal slopes must to be flat or gentle, with wastewater naturally flowing away from the building. This will ensure the effluent disperses evenly in the drain field.
- Soil Type is Key. It is also important to know your soil’s absorbency. Different types of soils behave differently towards wastewater. Sandy soils, characterized by their high porosity, allow better drainage and absorption, making them excellent choices for use in drain fields. On the other hand, clay soils might be problematic due to their low permeability. Conducting a PERC (percolation) test can help determine how well the soil on your property absorbs water and which placement is best for your drain field installation.
- Distance from Water Sources. North Carolina regulations require a minimum horizontal distance of 100 feet between your drain field and public/private water supply sources. This safe separation prevents wastewater from coming into contact with and contaminating drinking water, thus protecting your family’s health.
- Steering Clear of Obstacles. A drain field should not be installed near trees or structures that could affect its efficiency. Trees near the drain field could send roots into it and eventually block the drain lines, thus impeding its operation. On the other hand, heavy objects placed over the drain field area could increase soil compaction, thereby reducing the soil’s ability to absorb wastewater.
