Getting rid of sewage and effluent is called sewage disposal. If sewage is not disposed of or contained correctly people may come into contact with it and get very sick.
There are different ways to dispose of sewage. Whichever method is used, it is important to make sure that it does not:
- cause dangerous conditions which allow people to come into contact with disease-causing germs
- cause pollution of a water supply
- allow the breeding of insects such as mosquitoes or cockroaches which can carry disease-causing germs inside or on their bodies as a result of eating or walking in sewage
- produce bad smells
