Septic pumping costs $395 to $610, depending on the septic tank size. Septic pumping involves removing liquid and floating solids from the septic tank with a hose. The term "septic pumping" is often used interchangeably with "septic cleaning" but the services are not the same.
Septic cleaning costs a bit more because it takes the pumping process one step further. The service pumps the waste out and then cleans off any sludge from the bottom of the tank and residue stuck to the walls. Over time, this residue accumulates and clogs the drainpipe.
