The answer to 'septic tank vs' is that a septic system and a sewer system are two different ways to handle wastewater from your home. A septic system is an onsite, self-contained wastewater treatment system, while a sewer system connects to a municipal wastewater treatment facility. The main differences are the location of the treatment, maintenance requirements, and overall costs.
Septic systems are typically found in more rural or suburban areas without access to a municipal sewer system. They require regular maintenance like pumping the tank and inspecting the drain field, but can be more cost-effective than connecting to a sewer system. Sewer systems are more common in urban and suburban areas, and the municipality is responsible for the maintenance and treatment of the wastewater. However, connecting to a sewer system often has higher upfront costs for the homeowner.
