✓ Meanwhile, the septic tank, which is usually underground and happens to be a water tight container, retains the waste water for a period long enough to enable the solid materials sit at bottom and start to dissolve. In the process, both oil and grease will float to the top as a layer of scum.

✓ Any wastewater that’s liquid will then leaves through the drainfield out of the septic tank.

✓ The drainfield, on the other hand, is a shallow excavation that’s made of unsaturated soil. The treated water is transported via the piping onto a porous surface which enable the filtration of the wastewater into the surrounding soil. The soil, in turn, treats and disperses the wastewater.
