What is the sewage system?
The waste water system moves waste water and materials from its original point to be able to dispose of or treat. There are three main varieties of modern sewer systems. Cities often have two types of systems, a storm sewer that moves clean and refuses, and the waste sewerage system, which moves dirty water and human waste. In areas where buildings are not connected to the city system, the third type of sewage system, septic tank. This removes waste water from the house where overtime is.
Sewerage systems have risen with the invention of cities. As a result, there are records that waste systems have been returning for almost 5,000 years. While most of these early systems were basic, some of these systems are still in operation. The oldest sewer system that is still used is almost 3,000 years old. This case is an exception rather than a standard, and most sewer systems are not over 200 years.
MostCities use two unconnected sewer systems, Storm Sewer and waste sewerage. Storm Stowers collect rainwater and other clean waters. These sewers have drainage grids commonly visible on the streets of the city. This system usually contains street and dirt, but no real waste water. In many cases, the city simply filters this water to remove any garbage or rejection and allow it to flow, untreated, into a local water source. Because the water is clean, it usually will not have any environmental impact.
The second type of sewer system is for drainage. This is a real urban wastewater system. This system collects human waste and waste water from homes and business and pumps into a treatment facility. This device filters water and removes solids such as human waste and garbage. Water and solids pass through various processes where there are harmful microorganisms in clothCH removed, killed or consumed. Once the water level is harmful bacteria is back to natural levels, the water is allowed back to the local system.
The third common wastewater system is a septic tank. This type of system is located if there is no available connection to the urban system. With the septic tank, the waste water moves a short distance from the building and holds in the tank. The solids float down and are cleaved by specialized organisms in the tank. The remaining liquid, now much cleaner, is released into the surrounding country. Once there are natural processes remove the rest of the waste before the water returns to the local system.
