Before installing a septic system in Arizona, you must know if the soil can handle it. That\u2019s where a site & soils test comes in. Also called a percolation test or soil evaluation, this step is required by the Arizona Department of Environmental Quality (ADEQ) for all new septic installations.<\/p>\n

At HomeField, we walk you through the process, explain the results, and design a system<\/a> that fits your property.<\/p>\n

What a Site & Soils Test Reveals<\/h3>\n

Septic systems rely on soil to filter and absorb wastewater. If the ground is too dense, rocky, or slow-draining, problems follow. Backups, contamination, and complete system failure can result. Soil that drains too quickly can also cause issues because wastewater may reach groundwater before treatment occurs.<\/p>\n

ADEQ uses the site & soils test to determine whether your property qualifies for a conventional system or requires an alternative design.<\/p>\n

How a Site & Soils Test Works<\/h3>\n

During testing, an engineer or licensed professional evaluates your soil using one of two methods:<\/p>\n
