Frequently asked in San Francisco

What is the purpose of a septic tank?

The liquid effluent then flows out to a drain field for further purification before being safely absorbed into the soil.

How long do septic tanks usually last?

With proper and regular maintenance, septic tanks can last for 20 to 30 years, or even longer.

Routine professional attention is key to maximizing the system's longevity.

How often do septic tanks need to be emptied?

The frequency of septic tank pumping in San Francisco typically ranges from every 3 to 5 years, depending on the tank size and household usage.
