What's the difference between a septic and a sewer system?
assistant
The main difference between a septic tank and a sewer system is that a septic tank treats wastewater on-site, while a sewer system transports wastewater to a treatment facility. Septic tanks are designed to treat waste water from households, whereas sewer systems are typically used for industrial and commercial buildings. In addition, a septic tank requires periodic maintenance, while a sewer system is more permanent.
