Proper Septic Tank Cleaning

Homes with septic tanks consist of a drain field and an actual septic tank. In order for your wastewater treatment system to work properly and last for as long as possible, it needs to be cleaned or pumped out, when solids begin to reach the storage capacity inside the tank. This is typically when the total accumulation of solids reaches between 30 percent and 50 percent.

Before beginning to pump the tank, it is vital that you inspect the level of the liquid in relation to the outlet pipe. If the level of the liquid is below the pipe, this is usually an indication of a leak in your tank. If the level of the liquid is above the pipe, this indicates an issue with the drain field.

After inspecting and confirming the liquid is at the correct level, you can begin to pump the tank from the manhole. If you have to pump from the inspection ports, make sure you get both ports to ensure you reach the entire tank. When pumping, keep an eye out for any backflow from the pipe. If it is a small amount, this usually indicates a sag in the pipe and a large backflow indicates a system backup. Make sure to pump the tank thoroughly by using a septage spoon and back flushing in order to loosen any sludge in the tank’s corners. So not leave waste in the tank and do not pressure-wash or scrub the walls inside the tank.

After you have completely pumped the tank, check for any structural damage such as cracks or holes. After you have completed the entire process, you will need to file a report with your local town hall that you have completed the pump-out.
