What is the typical lifespan of a properly maintained septic system?

A properly maintained septic system typically has a lifespan of 20 to 30 years. This duration can be influenced by various factors such as the size of the system, the amount of wastewater generated, the environment in which it is installed, and the level of maintenance performed. Routine inspections, proper usage, and timely pumping of the tank can greatly extend its life. As a result, many septic systems that are well cared for can function effectively for two to three decades, making this the correct choice for the lifespan of such systems.
