We also look at the accessibility of your tank lids; if they are buried deep underground or hidden under landscaping, extra labor is required to reach them. The distance from our truck to the tank also impacts the setup time. Every property has unique plumbing needs, and exact pricing is confirmed free on the call.

Frequently asked in Austin

What is the purpose of a septic tank?

The main purpose of a septic tank for Austin residents is to treat wastewater from homes without access to the city sewer. It separates solids from liquids, allowing solids to decompose. The liquid effluent then flows to a drain field for further treatment. This process prevents sewage from backing up or polluting local waterways.

What is the average cost of a septic tank?

How long do septic tanks usually last?

Septic tanks in the Austin area can last for 20 to 30 years or more with proper maintenance. Regular pumping and avoiding flushing inappropriate items are crucial for longevity. Neglecting these steps can lead to premature failure and costly repairs. Consistent care ensures optimal performance.

How often do septic tanks need to be emptied?

For most Austin households, pumping your septic tank every three to five years is recommended. This frequency depends on the tank's size and your water usage. Overfilling can cause solids to enter the drain field, leading to system damage. Regular pumping is a vital preventative measure.
