Which process occurs first in the septic system?

In a septic system, the first process that occurs is the collection of wastewater. This step is crucial as it involves directing sewage from the home or building into the septic tank. When wastewater is generated from various appliances and fixtures, it flows through the plumbing and into the septic tank, where it is temporarily stored. This initial collection is essential for the subsequent treatment processes.

Once the wastewater is collected in the tank, it undergoes treatment, where solids settle to the bottom and liquids flow out to the drain field for further processing. However, treatment cannot occur until the wastewater has been collected. Understanding this sequence is vital for anyone involved in septic system installation or maintenance, as it lays the groundwork for effective wastewater management and system functionality.
