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

The typical lifespan of a properly maintained mound system is 20 to 30 years. This time frame reflects the design and construction quality, regular maintenance, and environmental conditions that contribute to the longevity of the system.

Mound systems are engineered to provide adequate treatment of wastewater through a combination of soil filtration and microbial action. Over time, systems may begin to experience issues such as clogging or reduced effluent quality due to accumulated solids, but with consistent maintenance—such as monitoring the system's performance and periodic pumping of the tank—these problems can be mitigated.

When installed properly and given the necessary upkeep, a mound system can effectively manage wastewater for two to three decades, making this lifespan a key consideration for homeowners and installers alike. Understanding the typical longevity helps homeowners plan for eventual system replacement and ensures they maintain it to maximize its operational lifespan.
