Septic Tank Vs Public Sewer. Which Is The Right Choice for Your Home? A septic system is a type of sewage waste disposal system for households and light commercial use. These systems are used where access to a municipal sewer system is not available or practical. Septic systems are used more commonly in rural America. More than 60 million households in America use the septic system.
In contrast, a sewer system carries away wastewater from homes and businesses to a central treatment plant. The water is treated before being released back into the environment.

The major advantages of septic tanks are:

  • They are affordable
  • They don’t require electricity to function.
  • They can be used off grid.
  • They are environmentally friendly because they use natural processes to break down wastes

what is a public sewer?

The word ‘sewer’ is derived from the Latin word ‘exaquaria’ and the French word ‘sewiere’ meaning water channel. It is a system of pipes, usually underground, that carry waste away from homes and businesses to treatment plants. Public sewers are part of the water management system that collects wastewater from homes and businesses in urban areas. They are considered public property, so it is illegal for people to damage them intentionally or accidentally.

Public sewers run through the streets of towns and cities. Public sewers are an important part of our infrastructure. They provide sewage services for homes, businesses, and other buildings in the area. Sewer networks also help to reduce pollution by collecting rainwater runoff before it has a chance to enter waterways or groundwater supplies. The water that is collected is then treated before being released back into the environment as clean water that is safe for people to use again.
