A soil percolation test, often required before building a septic system, assesses the rate at which water drains through the ground. The procedure involves digging holes in the intended drain field area and saturating them with water. The speed at which the water level drops is then measured to determine the soil’s suitability for wastewater absorption. For example, if water drains too slowly, the soil may not adequately filter effluent, leading to system failure and potential environmental contamination.
This evaluation is crucial for ensuring the proper functioning of septic systems and protecting public health. By verifying adequate drainage, it minimizes the risk of wastewater surfacing, contaminating groundwater, and spreading disease. Historically, these tests have been implemented to prevent unsanitary conditions and safeguard water resources. The findings from the assessment dictate the type and size of septic system that can be safely installed on a particular property.
