Percolation Testing – Engineered Septic SC – Educate yourself and read our post.

That meaning a percolation test is a test to determine the absorption rate of soil for a septic drain field or “leach field”. The results of a percolation test are required to properly design a septic system. In its broadest terms, percolation testing is simply observing how quickly a known volume of water dissipates into the subsoil of a drilled hole of known surface area. While every jurisdiction will have its own laws regarding the exact calculations for the length of line, depth of pit, etc., the testing procedures are the same.

In general, sandy soil will absorb more water than soil with a high concentration of clay or where the water table is close to the surface.

We are onsite today in York SC because of a failed perc test. The soil scientist upon the first visit determined there was excessive buildup of fill placed on top of already bad soil. Because of this we had to open the ground and dig pits to further preform testing. The next testing incorporated in our scope of work will include whats called “Saturated Hydraulic Conductivity Testing with constant head permeameters”. Simply defined as water movement through saturated media – even simpler terms again…means the measure and rate of water as it passes through soil from the undisturbed ground. This is why we dug the pits today.This determines how the engineer will spec the design for our installation and give you a successful Engineered System. See the diagram below that shows a regular test dig vs the larger excavation to the right. If you were able to understand this posting please like our Facebook page not just the posting.
