Every business or household in a developed country has a working sewage system. This is a required element for the maintenance of a healthy environment. In cities sewage is managed by the municipality and nature has its own mechanism for managing waste products. The disease is always present and easily stoked by a lack of sewage facilities. Parasites thrive in waste materials and are transported through air and water. Holding sludge and scum is the job of septic tanks. The unit is installed on properties to protect families from bacteria that might accumulate and cause disease. In areas outside of cities, there are usually no sewer systems. Therefore, in place of a sewer system disposal, there are septic systems. 

Effects Of Sewage On The Environment 

• Disease
• Nutrient enrichment
• Oxygen depletion

WATER Pollution From Sewage Waste: 

Sewage waste adversely affects those exposed to it, causing diseases like Dysentery, E.coli, and Cholera. If treated properly by the correct servicing of a septic system, the environment is protected. However, there are some sewage accidents that are beyond control, like the weather. 

There are times when it rains heavily. It settles in some places and floods the septic system. The containers are built to hold sewage but the drain areas become saturated with water, and sewage can back up into the home. However, there are signs that a problem exists, toilets start to operate with less efficiency. During heavy rains try to flush less water into the system to prevent, backup. Even with the servicing of a septic system, heavy rain may cause overflow and increase chances of environmental pollution. A bacterium from sewage is also responsible for typhoid. 

With the increase of homes built in rural suburbs, the leakage of septic waste during heavy rains can increase, thereby polluting soil and water. Back up waste gets into homes or leaks into the yards is the reason for emergency repair. One way to avoid such a fiasco is to have the system checked or cleaned professionally before the rainy season begins. Septic Systems kept clear of clogs are an asset to the environment. However, those un-cared for damage the ecosystem by supplying a buildup of contamination that filters into the water system and it leaves puddles for the breeding of mosquitoes and other parasites. 

Tank Composition: 

• Receiving tank- accepts the waste
• Leaching system-drains and disburses liquid to the surrounding soil

Waste moves through the drain from the home and enters the tank. Waste settles to the bottom leaving a liquid residue called scum. This line carries waste from the home primarily from bath areas. The sewage flows into a reservoir called a septic tank. This underground container protects surface land from bacteria that cause disease. 

Chemicals developed in waste products help algae to grow in water. Then bacterium takes oxygen away from water sources. This prevents the inhabitants of the water from breathing. Epidemics have started from uncontrolled sewage. Each municipality has regulations regarding the installation of a sewage control system. Many containers are designed standard. However, there are industrial level facilities for larger organizations.
