Sewage treatment has evolved a great deal throughout the ages, and from now on 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. However not everyone is connected in this manner, and there is many houses, buildings and communities that do not have a direct connection to the municipal system. In cases such as these, 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. According to the size, it can serve a single house, or a whole community. Then, every so often, 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 find the sediment, with the surface scum at the top. The inlet for the pipe is often in between both, along with the top of the tank is where the hatch is. Some septic tanks also have an hybrid system, where the top section is sent out via other pipes to irrigate fields, or simply down onto vast plains to evaporate. It is a concept that was fairly popular on farms, and could 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 during the past few years, due to the fact that a leaking tank could cause major problems to the environment. It might also infect freshwater supplies, that can be bad for humans and animals. Sediment also produces a quantity of 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 more preferable served with a good municipal system, where excrement doesn’t have to become stored and sent by truck, instead everything is connected and sent off directly. You end up saving a great deal of potential issues. Still, it is really not always possible, and as such sceptic tanks still play a role even today.
