The biological treatment septic system gets installed at the Westerly house.

It’s time for the sophisticated septic system to be installed at the Westerly house. The 1500 gallon primary and secondary tanks are buried into the ground. Installer Rick Pezza shows Richard Trethewey the steps, starting with a filtered pump that draws liquid in short cycles from the second tank to a treatment pod. In this pod, the dirty liquid drips down over hanging filter sheets filled with microorganisms that convert the ammonia into nitrogen. Through this biologic process, nitrogen gas gets released into the atmosphere, oxygenated water returns to the main tank, and the remaining treated liquid goes down through the sand filtered field.
