Industries which are connected to the sewers should have to treat their wastewaters before they are allowed to discharge them into the sewers. This is important because they may contain materials which will harm the sewers or the treatment plants or may be a danger to the people who work in looking after the sewer system More sewage water treatment plants should be installed in cities and industrial belts' where the treated water can be reused.

The first commercial sewing pattern for home sewers is attributed to Butterick Publishing Company, founded by Ellen Curtis Demorest in the 1860s. Demorest introduced the concept of printed sewing patterns, which allowed home sewers to create garments more easily and accurately. This innovation revolutionized the way people approached sewing at home, making it accessible to a broader audience.
Sewers can affect plants by carrying pollutants such as heavy metals, chemicals, and pathogens that can contaminate the soil and water where plants grow. Excessive sewage can disrupt the soil structure and introduce toxins that inhibit plant growth, leading to environmental degradation and harm to plant life.
Sewers typically lead to a wastewater treatment plant or a body of water like a river or ocean. These facilities are designed to treat and filter out harmful substances before releasing the water back into the environment.

Because during a heavy down pour the sewerage treatment is over loaded and raw sewerage can enter potable water systems
Four sewage disposal types include typical septic systems, sanitary sewers, storm sewers, and combined sewers.

Cities built sewers and supplied purified water
The cities were planned and laid out with roads in a grid system, sewers and running water to houses, before being built.
