The answer to 'difference between septic system and sewer system' is that a septic system is a self-contained wastewater treatment system located on the homeowner's property, while a sewer system is a centralized wastewater treatment system managed by a municipality or utility company. Septic systems treat and dispose of wastewater on-site, while sewer systems collect and transport wastewater to a centralized treatment facility.
Septic systems are typically used in rural or suburban areas where public sewer infrastructure is not available, while sewer systems are more common in urban and densely populated areas. Septic systems require regular maintenance and periodic pumping, while sewer systems are maintained by the utility provider. The costs and installation process also differ, with septic systems generally being more expensive to install but having lower ongoing costs compared to sewer connections.
