Sewage ....What it's Impact on Environment?

Sewage (swge.) Is the mainly liquid waste containing some solids produced by humans who typically consist of washing water, feces, urine, laundry waste and other material which goes down drains and toilets from households and industry.


Swge. Services

Is a system for collection and disposal of swge. by sewer pipes (sewers) and takes it for treatment or disposal.

Where a main swge. system has not been provided, the swge. may be collected from homes by pipes into septic tanks or cesspits, where it may be treated or collected in vehicles and taken for treatment or disposal.

Properly functioning septic tanks require emptying every 2-5 years depending on the load of the system.

the swge. and waste water is also disposed of to rivers, streams and the sea in many parts of the world.

Doing so can lead to serious pollution of the receiving water.

This is common in third world countries and may still occur in some developed countries, where septic tank systems are too expensive.


Treatment

The swge. treatment is the process of removing the contaminants from swge. to produce liquid and solid (sludge) suitable for discharge to the environment or for reuse.

A septic tank or other on-site waste water treatment system such as bio filters can be used to treat swge. close to where it is created.

It is a form of waste management…………………

Well-organized swge. services prevent pollution of the environment by managing the collection, treatment, and recycling or safe disposal of swge. in the environment.
