How many years will a new onsite sewage treatment system last?
Like any product we buy, longevity greatly depends on use and maintenance. However, a system that has been properly designed and installed, used in the manner for which was designed, and properly maintained, can be expected to provide service from twenty to twenty-five years, on average. Some parts of the system such as alarms, switches, pumps, and filters will most likely have to be replaced over the lifetime of the system. Each onsite sewage treatment system is designed specifically for an individual site so the variables impacting the longevity of the system differ as well from system to system. This is a good question to discuss with your Installer.
