The solids materials remain for degrading. The wall separating the chambers allows for liquid only to move to the second chamber. Separates the solids from the liquids- The solid waste settles at the bottom of the tank.Receives the wastewater from the house- all the house wastewater goes to the septic tank through one inlet.How a Septic Tank WorksĪ septic tank works in four basic steps. In addition, it should last for decades with no problems. Septic Tank Construction DrawingsĪ well-maintained septic system is odor-free and requires less emptying. Some septic tank designs include water pumps so as to increase the volume and velocity of water drainage. As a result, the drainage pipes fill more evenly and preventing premature clogging of the drains, therefore, extending their life. A wall with openings between the floor and roof of the tank separates the chambers. Some septic tank design has 2 chambers while others have 3 chambers. It has one end connected to an inlet from the toilets and sometimes an outlet connected to the drain field.
The floor has a slight slope of 10 percent towards the sludge outlet. The floor and side walls are made using concrete and plastered to render a smooth surface. The two compartments interconnect above the sludge storage using pipes or square openings.Ī concrete or plastic tank is the best to use. It, therefore, perform better than the single compartment tank. The wall separating the two is about two-thirds the length away from the inlet. Larger capacities are the best fit for a two-compartment tank. It is best to construct a single compartment for small capacity septic tanks. As a result, the tanks will require emptying from time to time. The wastewater will collect at the slung heap up at the bottom. Most septic tanks just separate the solid and liquid waste material. It’s basically a type of biodigester, only that it lacks the functionality of gas collection and waste treatment.
