However, how do you provide sewer service in rural areas that is not only efficient, but sanitary, for a residential or commercial structure? In this course, we will look at common terminology, explanations of the system components, designs using gravity and pump systems, location considerations, and the regulatory codes.  \nWe will start “at the beginning” and then progress through the sequence of components…from the septic tanks to the drainfield and the design involved in each of these components. This course is not intended to be all-inclusive in the design and installation of septic system but is intended to provide you with knowledge of how aseptic system works, the components that comprise the system, the calculations, and the considerations involved in a septic system for a rural structure. Obviously, these same principles apply to all septic systems but the regulations do vary somewhat from state to state.  \nA residential mounded septic system  \nDesigning Septic Systems  \nHistory of Septic Systems  \nThe use of septic systems is nothing new and dates back to the late 1800s. Prior to that time, the outhouse was the standard bathroom. It typically consisted of a hole in ground with a wooden bench centered above the hole. And if you’ve ever had the “opportunity”to use one, you quickly realize they’re not very appealing. The septic tank system is believed to have been invented in France in the 1860s. And it didn’t take long before it was being used in the United States. The first known installation of a septic tank in the United States was in 1876. With the increasing availability of electricity and pumps to provide running water inside buildings, it much longer before the bathroom moved indoors as well.  \nEach state has developed its own codes to regulate the installation and use of septic systems. Florida uses Florida Administrative Code, Georgia uses the Department of Human Resources Chapter 290-5-26, Texas uses Texas Administrative Code Title 30 Part 1 Chapter 285. Regardless, always check the code requirements for the state in which the system will be constructed. There are differences, especially in system loading rates and setback requirements.  \nTHE COMPONENTS  \nA typical gravity septic system consists of a septic tank, filter, effluent lines, a header pipe or distribution box, and a drainfield. Other systems may also include a dosing tank, an effluent pump, or an Aerobic Treatment Unit (ATU) . The septic system can bea gravity system or a pumped system depending on the site conditions. And it could bean in-ground or an above-ground (mounded) system regardless of it being a pumped system... as we’ll see a little later in this course.  \nDesigning Septic Systems  \nThe septic tank is where the breakdown of the sewage occurs and it happens in an anaerobic condition (meaning without oxygen) . The anaerobic conditions are referred to as being \"septic,\" which is how the system got named. Typically a concrete or“plastic” tank is placed about five to ten feet from the building. The building’s sewer lines are fed by gravity into a single pipe that then enters the septic tank.  \nThe septic tank holds three layers of waste. The top layer is referred to as the scum layer which floats in the tank effluent until the bacteria digests it and causes it to sink to the bottom of the septic tank. The middle layer is the effluent layer consisting of the digested sewage in a liquid state. And the bottom layer is the sludge layer. It consists of the solids which are not digested and therefore will build up slowly on the septic tank bottom.  \nThe digeste","cbCaioMiU7jPTI5S","https://ap.wps.com/l/cbCaioMiU7jPTI5S","pdf",2054142,42,"English","# Course Description\n## History of Septic Systems\n## The Components\n### Gravity and Pump System Concepts\n## Septic Tank Function and Layers\n## Septic Tank Filter and Effluent Path\n# Septic Tank Installations\n## Advantages and Disadvantages of Concrete Tanks\n## Advantages and Disadvantages of Plastic Tanks","[{\"question\":\"本课程主要讲解哪些内容？\",\"answer\":\"课程围绕化粪池系统的设计展开：术语与部件解释、从化粪池到渗排场的系统流程、重力与泵送系统设计思路，以及选址与位置考虑与法规要求。\"},{\"question\":\"重力式与泵送式化粪池系统有什么区别？\",\"answer\":\"课程说明化粪池系统可为重力系统或泵送系统，具体取决于现场条件；同时也可采用地下或地上（覆土式/灌土式）的形式。泵送系统通常涉及 dosing tank 或泵与后续排入渗排场的路径。\"},{\"question\":\"化粪池在系统中起什么作用？\",\"answer\":\"化粪池负责在厌氧条件下对污水进行分解，并形成三层结构：表层浮渣层、中层出水/流出层、底层污泥层。随后消化后的液体会通过滤网进入渗排场，或在某些泵送配置中先进入 dosing tank 再排入渗排场。\"}]","Septic System Design - Course 077 - Designing Septic Systems | PDF",1792793664,106]
