Residential Percolation Testing

At LePew Industrial Inc., our septic professionals are able to arrange a percolation test (perc test) of your leach line, all done by a certified technician. Whether you are having a new septic system installed or having issues maintaining your tank’s seepage level, we may recommend a perc test. This determines whether your leach lines are working properly. A residential perc test will ensure you how quickly a high volume of water will be absorbed in the subsoil of a drilled hole. The results of a percolation test are required in order to properly design or diagnose any issues. For any questions, feel free to contact us today! Our helpful professionals are available 24/7!

Do I Need A Percolation Test?

A perc test is highly recommended if you are in process of purchasing a home or land in a rural area. On rural sites without municipal sewage systems, a failed percolation test means that a house cannot be built due to city and county codes. It is best to purchase a property that passes a perc test. In many parts of the country, prime building sites have become prohibitively expensive, so rural areas that do not pass a perc test are quite common.

Typically, soils with high sand and gravel amount drains the best while soils with a high clay content or solid rock are not as effective. Most soils fall in the middle with a mix of course sand and gravel particles, miniscule clay particles, and small slit particles. A soil evaluation or a perc test is done to determine a site’s suitability.

If your property fails a perc test, you still have other options. For sites that have high water tables, it may be possible to “de-water” the leaching area by properly placing gravel-filled trenches and sub surfacing drain pipes to conduct water away from the drain field.

How Do Percolation Tests Work?

A typical perc test is done by three of more holes dug about 30 – 40 feet apart in the drain field area. Holes are usually 6 – 12 inches in diameter and about 2 feet deep. Our experienced technician will then place two inches of gravel or clean sand into the bottom of each hole. Since the perc test is meant to simulate the actual conditions in a working septic system, the soil is then “pre-soaked” for many hours. LePew Industrial Inc. experts will then fill each hole with water up to 6 inches from the gravel, and measure how much the water drops in 30 seconds. The time it takes for water to fall one inch is carefully documented and used to determine the percolation rate, usually expressed in minutes per inch of drop. Test results are typically good for couple of years.
