A percolation test, conducted on a parcel of ground, assesses the soil’s capacity to absorb water. This evaluation is fundamental in determining the suitability of the site for subsurface wastewater disposal, commonly through a septic system. The process involves digging holes in the proposed drain field area and measuring the rate at which water dissipates into the surrounding earth. The resulting percolation rate, typically expressed in minutes per inch, is a key factor in the design and approval of septic systems.
The significance of this evaluation lies in ensuring proper wastewater treatment and preventing environmental contamination. An adequately functioning septic system relies on the soil’s ability to filter and purify effluent before it reaches groundwater. Historically, improperly designed or sited septic systems have led to groundwater pollution and public health hazards. Therefore, this assessment plays a crucial role in safeguarding water resources and ensuring the long-term viability of on-site wastewater treatment.
