Frequently asked in San Antonio

What is the purpose of a septic tank?

A septic tank is a crucial part of your home's wastewater treatment system. It collects all household wastewater, allowing solids to settle and form sludge. Liquids then move to a drain field for further treatment and dispersal into the soil. This process is vital for preventing pollution and protecting public health in areas like San Antonio.

How long do septic tanks usually last?

Septic tanks themselves can last for decades, often 20 to 30 years or even longer with proper maintenance. However, the drain field associated with the tank has a shorter lifespan, typically 15 to 25 years. Regular pumping and avoiding harsh chemicals are essential to maximize the life of your entire system in the San Antonio area.

How often do septic tanks need to be emptied?

The frequency of septic tank pumping depends on several factors, including tank size and household water usage. As a general guideline, most tanks need pumping every 3 to 5 years. For a typical San Antonio household, this ensures efficient operation and prevents potential issues. It's always best to consult with a professional for a personalized recommendation.
