Sewage treatment has evolved an awful lot throughout the ages, and today most new communities have state of the art sewage systems, with every house connected by pipes to the treatment center, which goes through the sewage and cleans it up, before sending it back down river. But not everyone is connected in this way, and there is many houses, buildings and communities that don't have a direct connection to the municipal system. In a case like this, usually they will use septic tanks.
The earliest types of sewage systems was to simply make digs in the field, and sometimes on the side of the roads in urban areas, where people would deposit their trash and excrement, to be brought down by the rain in a source of water. It was unbelievably insoluble and dirty. It quickly became the source of many diseases, coupled with being very smelly. It didn't take long for individuals to realise the benefits of getting that stuff under ground, in a special container. This is exactly what a septic tank basically is.
In many instances, a huge container, put into the earth, with pipes carrying sewage connecting into it. Based on the size, it can serve a single house, or a whole community. Then, now and again, a truck comes in and sucks everything inside the tank up to the truck, before sending it up to a treatment centre. It's a way to have a sewage system that works, without being connected to a treatment centre directly, either because the building is far from town, or inside a closed community.
A modern septic tank usually has several levels. At the bottom, you discover the sediment, with the surface scum at the top. The inlet for the pipe is often in between both, as well as the the surface of the tank is where the hatch is. Some septic tanks also have an hybrid system, in which the top section is sent out via other pipes to irrigate fields, or just down onto vast plains to evaporate. This is a concept that was fairly popular on farms, and can save a great deal of money, although it isn't always environmentally friendly. The sceptic tank itself is usually made from metal, and has to be surrounded by a cement exterior. Laws for such tanks have become more severe in the past few years, due to the fact that a leaking tank could cause major problems to the environment. It can also infect freshwater supplies, that can be bad for humans and animals. Sediment also produces a amount chemicals, that can easily be dangerous.
Overall, a sceptic tank is a way to get your sewer system in balance when you have no other choice, but life of today is much better served with a good municipal system, where excrement doesn't have to become stored and sent by truck, instead things are connected and sent off directly. You end up saving a great deal of potential issues. Still, it is really not always possible, and as a result sceptic tanks still play a role even today.
