A Photographic Guide to Pumping a Septic Tank

Septic System Safety Warnings

This septic care guideline describes the steps in pumping and cleaning a septic tank. While it is common for a septic service company to send a pumper truck with a sole operator, pumping septic tanks is an inherently dangerous procedure and I advise against working alone. An operator can be injured, or overcome by fumes such as methane gas. Don't lean over or crouch down at the tank opening such as shown in the photo above. In this example case the operator was not working alone. Having a buddy watching is invaluable. If someone does fall into a septic tank, do not enter the tank to try to save them - call emergency rescue. Double fatalities have occurred when a second worker entered a septic tank to try to safe the first who had entered the tank and was overcome by gases. Because cleaning septic tanks involves potentially dangerous hazards (cave-in, collapse, methane gas explosion, or asphyxiation) readers should be sure to read our Septic Safety Warnings article. If a cesspool, drywell, or seepage pit is or might be installed, be sure to read Cesspool Safety Warnings.
