Excavation for a septic tank system is an important step in the septic tank installation process. It is a primary step that helps to ensure the smooth functioning of the septic tank system. It is necessary to have a thorough understanding of what happens during excavation for a septic tank system before any other steps are taken. Any doubts about excavation for a septic tank system should be raised with the help of an expert on septic tank installation. While any professional firm dealing with septic tank installation may charge a reasonable fee, it is advisable to do thorough research on the firm and the fees charged by the firm. Good research would save the user from unnecessary expenses.
There are different types of excavating contractors available in the market. The most common type of contractor working for any type of septic tank system is the back-fill excavators. These excavating contractors have a bucket attached to their trucks that contain a huge amount of water that is used for breaking up soil layers that reach up to the depth of the tank. Back-fills are used when the excavating contractor needs to access areas that are difficult to dig.
In case there is no tank available, back-fill excavators are used along with backhoes. Backhoes are huge vehicles with a bucket attached to the body and they too are used to excavate soil that reaches up to the depth of the septic tank. Screed excavators are used to moving soil and other debris not within the area of a septic tank. It is important for any user of these excavating contractors to know the differences between them so as to avoid any misunderstanding of any kind.
Before starting any excavating work, it is very important for a user to have a proper plan for the excavation and the design for the tank. Any movable object such as a crane or wheel must be planned and locked into place before use. Any movable object that is placed in the way of excavating contractors or that comes in contact with the septic tank must be lifted out of the way. The only exception to this rule is if any part of the excavating contractor’s equipment comes into contact with the pumped wastewater produced from the tank.
The excavation for a septic tank begins with the removal of soil layers that are located directly under where the tank is located. After this, the top layer of soil is then excavated leaving an area of at least one foot of gravel for the septic pipes. The excavation is to make sure that the septic tank can be properly laid out and maintained before a new one can be installed. The newly excavated dirt is then leveled off and a machine is used to level and compact the newly excavated dirt.
Once the dirt has been excavated, the newly compacted earth is pumped out and the dirt is leveled off. After the entire excavation is over, a machine is used to carefully set the tank on top of the excavated dirt. A pump is used to ensure the septic system works correctly before it can be officially filled. After the septic tank is completely filled, the excavating contractor must then carefully dispose of all of the debris and excess sand that might be left behind.
