Using the muckrake and the vacuum simultaneously, the contractor continues breaking up sludge and removing it through the tube until the tank is sufficiently empty. After spending a few minutes breaking up the sludge and mixing it with effluent, the contractor sticks a large vacuum tube down into the tank. This angular, hoe-like tool has sharp edges that break up and agitate the sludge so it’s easier to remove. The pumping process begins with the contractor sticking a long tool called a muckrake down into the sludge layer of the tank. They may do an inspection of the tank to make sure it’s in good condition and verify that you do need to have the tank pumped. When the contractor arrives for the cleaning, they start by accessing the septic tank through the top cover and inspection pipe. When the tank gets to be about one-third of the way full of sludge, it’s time for a tank cleaning to remove buildup and sludge, preventing them from filling it and causing damage. A pump in the main tank sends the effluent up to a drainfield, where it filters down into the soil below the drainfield’s network of pipes, which have small holes for the effluent to escape.Īlthough bacteria work to decompose much of the sludge that remains in the bottom of the tank, they don’t work fast enough to prevent that sludge from building up over time. Heavier sludge sinks to the bottom, watery waste called effluent sits above that and a layer of fats and oils rests on top. In these tanks, the wastewater naturally separates itself into three layers. The waste and water that come out of the home empty into one or a series of tanks. In rural areas where there’s no municipal sewer system, homes often have septic systems. A septic system, on the other hand, is quite a bit different. When you take a shower, do laundry or use the restroom, the water and waste leave through the pipes and enter the sewer system immediately. These pipes are tied into the home’s plumbing, carry all of the home’s dirty water and waste away from the structure and transport it to a facility where the water is treated and cleaned. A home with a typical sewage system has pipes leading away from the home that tie into the larger municipal sewer.
