It has been an incredibly wet winter and early spring on Delmarva. We often have to let clients know that their septic system can’t be installed due to the soils being to wet. We have to wait for the soils to dry. I thought I would explain the reason why.

When the soils contain a lot of moisture they tend to smear when they are handled. Thats a big problem for installing septic systems. The interface between the soils and the stone or aggregate is incredibly important to a septic systems longevity, and we don’t want any smearing. Smearing can happen when the bucket is sliding through the soil to excavate it. It can also happen through footprints or other activities. The interface should be left in a rough and in a non-compacted state. Wet soils can be compacted much easier than dry soils.

We completely understand the frustration of not being able to get a system installed. We don’t get paid until the system is complete so we want to get the septic system installed as quickly as possible, but not at the expense of the system’s longevity. Hopefully this helps you understand a little bit about why we have to postpone installation on systems where the soils are simply too wet.
