What is the purpose of a septic tank?

A septic tank is a vital part of an on-site wastewater treatment system, primarily used in areas without access to public sewers.

This separation process is essential for preventing contamination and managing waste effectively. It's a critical component for many properties in San Francisco.

With proper and consistent maintenance, including regular pumping every 3-5 years, septic tanks can last for 20 to 30 years, or even longer. Neglecting this maintenance can significantly shorten the lifespan of your system and lead to costly repairs. Regular professional servicing is crucial for the longevity of your San Francisco septic tank.
