Do You Know the Average Septic System Life Expectancy?

Septic tank cleaning is one of the most important parts of home maintenance, particularly if you’re looking to stretch the life of your septic system for many years. But what can you reasonably expect out of your septic system’s lifespan, and how can you extend that lifespan for as many years as possible? Read on to learn more about how septic tank maintenance in San Francisco can keep your septic system flowing reliably for years to come.

How Long Should Systems Tanks Last?

One of the most important factors in determining how long septic system life expectancy is the kind of material from which your tank is made. Steel and concrete are two of the most common septic tank materials in use throughout the Bay Area. Steel tanks can last for 15 to 20 years before they can be expected to fail due to rust and corrosion. Concrete tanks are known to last longer, sometimes for 40 years and beyond, but even concrete tanks can fail due to cracking and erosion. The key is to regularly invest in high-quality septic tank maintenance and to practice safe drain-use to keep your septic system working properly.

Environmental Factors Affecting Septic Tank Life Expectancy

Beyond the type of septic tank you have, factors in the physical environment surrounding your home can affect your septic tank. Tree and plant roots are a common infiltrator of septic lines, causing cracks and clogs slowly over time. Soil percolation rate and groundwater conditions can affect absorption around your drainage field, which can impact the longevity of certain parts of your system. Finally, the presence of moisture and water around the septic system can negatively impact the septic system. Flooding or abnormally moist soil can shorten septic system lifespans and might cause backups in the short term.

Safely Using Your Septic System

Homeowner use can also affect the longevity of septic systems. Avoid flushing non-waste items such as trash, scraps, and dirt down the drain. Regular septic tank cleaning and connecting lines can help to minimize clogging and bursts, which means improved performance over longer periods of time.
