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 system, especially if you're not connected to a city sewer line. Its main job is to collect all the sewage from your toilets, sinks, and showers. Inside, it separates solids from liquids, allowing solids to settle and decompose over time while liquids flow out to a drain field.

What is the average cost of a septic tank and installation?

How long do septic tanks usually last?

With proper maintenance, a septic tank system in San Antonio can last for many years, often 20 to 30 years or even longer. Regular pumping and avoiding putting harsh chemicals down the drain are key to extending its life. However, the drain field might have a shorter lifespan and may require attention sooner.

How often do septic tanks need to be emptied?

How often your septic tank needs to be emptied in San Antonio really depends on the size of the tank and the usage by your household. A general rule of thumb is to have it pumped every 3 to 5 years. However, a professional can assess your tank's sludge levels to recommend the best schedule for you.
