How is raw sewage different from sludge?
Raw sewage refers to untreated wastewater containing a variety of contaminants, including human waste, chemicals, and organic matter. Sludge, on the other hand, is a semi-solid residue produced during the treatment of sewage. Sludge has had some treatment processes applied to remove solids and pathogens from the raw sewage.
What is sewage and how is it treated?
Sewage is liquid waste from households and retail areas that contains sanitary waste (Feces and urine), soaps, food scraps, water, cooking wastes etc.It is gathered and piped to sewage treatment plants. Depending on the complexity of the plant the treatment consists of:* Primary treatment: "De-lumping" the sewage and allowing the fluids to sit in lagoons for a period of time before discharge. Removed solids are disposed of to land.* Secondary Treatment: "Delumping" the sewage. Allowing the sewage to be mixed with bacteria in aeration basins which remove the dissolved organics. Removing the bacteria and discharging the treated water. Removed solids are disposed of to the land or anaerobically digested to generate methane. * Tertiary Treatment: The same as Secondary Treatment but the effluent is filtered and disinfected before discharge Storm water can also be considered as sewage. In many cases it has as many contaminants as sanitary sewage. I is generally simply settled prior to discharge to allow solids to settle out and oils to float to the top for removal
What work do they do at a sewage treatment plant?
Large items of waste are firstly removed from the sewage intake to prevent blockages throughout the cleaning process. Grit and smaller items are then removed using a filter, before chemical treatment is used to purify the water.
Can you acquire soil from a sewage plant?
Yes, you can acquire soil from a sewage plant if it has been treated and processed to meet safety standards. It's important to ensure that the soil has undergone proper treatment to remove any potential contaminants before using it for gardening or landscaping purposes.
How does sewage start?
Sewage is generated from a variety of sources, including households, businesses, and industries. It consists of wastewater from sinks, toilets, showers, and other sources, along with any solid waste that is flushed down drains. Once collected, sewage is typically treated in wastewater treatment plants to remove contaminants before being discharged back into the environment.

Not a storage pool for water?
Clean drinking water is usually stored in large tanks. Sewage treatment on the other hand refers to the process of removing the contaminants from the waste water.

What is the purpose of sewage disposal?
Here's the answer from Wikipedia. Sewage treatment, or domestic wastewater treatment, is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds. See this link for more details. http://en.wikipedia.org/wiki/Sewage_disposal
What kind of chemical to clear oil contaminants?
That will vary depending on the type of contaminate. Some contaminates cannot be removed with chemicals (e.g. metal particles - these need to be removed with a filter).
