When putting in a septic system, location is everything. This type of waste water handling arrangement is used mostly in residential areas that are not connected to a municipal sewer system and location on the property is crucial. Not only does proper positioning of the septic tank and drain field directly affect its efficiency and performance, it can be pertinent to how easily septic trucks for sale will be able to access it for routine maintenance.
Components and Positioning
In order for a private septic system to work trouble-free, it needs to be correctly positioned at its location in a way that it can do its job without adversely affecting the surrounding land and underground water table. There are two main parts to these systems, each of which must be correctly installed in relationship to the home or building itself as well as the neighboring land.
- Tank - Standard septic tanks are usually one thousand gallons or more, made of sealed concrete, and need to be buried away from the building yet within close range. In most areas, it is required that the tank itself be buried no more than five feet from the house and about two to four feet below the ground surface. The tank holds waste water and solids on a temporary basis; waste water disperses out into the connected drain field, while waste solids are routinely pumped out by a septic truck for later disposal at a designated waste facility. In order to have a smooth operation, the tank itself needs to be placed close to the home and within a straight line from the chosen drain field area.
- Drain Field - This is the area where waste water is led by a system of perforated pipes so that it can be gradually absorbed into the soil, where it will be naturally disinfected and cleansed and eventually become part of the natural underground water system. The drain field should be directly in front of the septic tank and is usually set off from the property some distance, connected by a main pipe, and then spread out into two to three other pipes so that waste water can be spread over a large area.
Keeping in mind the way a private waste water system functions, there are two critical aspects to be considered when deciding where to actually put the septic tank and the all important drain field:
- Soil Quality - Before installation can start, the soil located around a home or building must be tested to determine its type and whether it is suitable for holding a drain field. Soil with too much sand or clay will not allow for good drainage and would not be the best spot for a drain field. The land should preferably gently slope away from the building and septic tank in order to promote easier outflow. The drain field area must be selected first before deciding where to locate the tank.
- Pumper Truck Accessibility - For drain field and septic tank location, accessibility by pumper trucks is important. A common placement area for access ease is in the front yard of a home so that vacuum trucks can get close to the tank; it is preferable to avoid using exceptionally long lengths of suction hose as that will make the pumping job more difficult. The hoses need to be extended in a straight line as bends will slow pumping or cause clogging. The tank should not be positioned so that vehicles have to drive on overlying soil as drain fields and weather conditions can make the ground unable to hold the weight of a septic truck for sale. It is better if the service vehicle could use the road or driveway for septic system servicing.
Placement of a septic system is critical to how well it works and how easily it can be maintained. It should be placed in an area that meets all needs regarding: tank location from the building; soil fitness and grade; and straight, close accessibility by a septic truck for sale, which is after all a very important consideration!
