Septic tank cost and installation — Pomona, CA
Last updated: September 24, 2026
What affects the price
The final bill for septic service depends on a few specific factors. The total volume of your tank, how long it has been since the last pumping, and whether the technician needs to dig to find your lids will all change the bottom line. If the system is particularly difficult to access or requires repairs to internal components like baffles or filters, the labor time increases. We provide exact pricing confirmed free on the call.

What is a septic tank?
A septic tank is an underground wastewater treatment structure. It receives all the household sewage from toilets, sinks, and drains. Inside the tank, solids settle to the bottom, and grease floats to the top, while liquids flow out to the drain field. It's a crucial part of a home's plumbing system in areas without municipal sewer access. Proper maintenance is vital for its function.
