A percolation test, often shortened to “perc test,” is a soil assessment conducted to determine the water absorption rate of the ground. The test measures how quickly water drains through the soil, typically expressed in minutes per inch. The obtained rate is a key factor in determining the suitability of the land for a septic system. For example, a site with a very slow drainage rate might be unsuitable for a conventional septic system, requiring an alternative or advanced system.
This assessment is crucial because functional septic systems are vital for public health and environmental protection. In areas without access to municipal sewer systems, the ability of the soil to effectively filter wastewater is essential to prevent contamination of groundwater and surface water sources. Historically, improper wastewater disposal has led to disease outbreaks and environmental damage, highlighting the importance of proper site evaluation before construction. A successful evaluation allows for environmentally sound and cost-effective wastewater management.
