Sewage Treatment Plants Bring Safety To Public Health And The Environment

Sewage treatment plants (STPs) are large facilities that treat both domestic and commercial sewage. They can range from small rural stations to huge metropolitan sewage treatment plants that cover several cities. STPs increase the efficiency of sewage treatment by separating the insoluble materials in sewage from the soluble ones before they are considered for disposal or further processing. They can treat all kinds of sewage including industrial waste, domestic wastewater and industrial wastewaters.


Before sewage treatment plants can treat these kinds of wastes, they have to be modified first. The primary modification that is done is the elimination of grease, oils and other kinds of chemicals. This is usually done through the mechanical process called mechanical treatment. Another major modification is the introduction of biological and chemical filters that help to clean up the sewage.

In most places, where there is no sewerage system, a sewage treatment plant is built. The sewage treatment plant is responsible for removing the excess water from the sewage before it goes to the different sewage treatment plants, where it is normally treated. A sewage treatment plant is also responsible for removing the excess sewage and other waste materials from the soil and the ground where it is deposited. After the sewage treatment, it is usually sent for further treatment so that the used sewage can be removed from the land.

Specialized Units

Apart from sewage treatment plants, there are specialized units that are designed to treat highly contaminated sewage. These are known as septic tanks and they are very popular now. These are large storage tanks that hold huge quantities of sewage that is usually reused in the manufacturing units. The septic tanks are so big that it requires the construction of submersible pumps and pipes for its proper functioning. These septic tanks can’t be used for household sewage treatment because they are large and stationary and are used only for industrial purposes.

Before you construct your sewage treatment plant, you should first learn about its working. A sewage treatment plant is simply a machine that efficiently treats sewage. It takes out harmful substances from your water supply through a sewage treatment plant.

The sewage treatment plants are located inside the sewage pipes and treatment centres. They carry sewage from the sewage treatment plants to the sewer line, which transports it into the homes or business premises. Most of the sewage treatment plants in the US are located in New York, Los Angeles and Chicago. In some areas, such as New York City, wastewater can be difficult to manage as it is treated in many places including private bathhouses and showers.

Types of Sewage Treatment Plants

There are two types of sewage treatment plants namely inland systems and coastal systems. Inland wastewater is handled by large sewage treatment plants, which function through in-house systems and receive wastewater from different locations. These plants also manage the flow of chemicals as well as sediment used in the process.

The coastal system on the other hand treats sewage differently. It functions through the use of sewage treatment facilities that are dug into the seabed. A special dock is then created where the wastewater can come in direct contact with the sewage treatment plant. The sediments that gather along the way serve as filters for the solids before they are sent to the sewage treatment plant, where they will be processed into usable forms.

Most sewage treatment plants are designed for residential, commercial and industrial wastewater treatment. For each type of waste, there is a separate tank or holding tank. Before any processing can take place, these storage tanks are first cleaned and disinfected. Once this is done, the wastewater is pumped into the sewage treatment plant. Here it is put under high pressure and heat to break down the grease, fats and oils in the waste. This is followed by the separation of the cleaned water from the sewage and flushing it into the sewer system or else it is pumped directly into the drainage system.

Disinfection is done once all the waste is treated. The entire process is a continuous one. Plants need a regular check-up to ensure that there are no clogs in the sewage system. If there are clogs in the sewage system, they will need to be manually removed. This will also require the attention of a qualified technician.
