What's the difference between a septic and a sewer system?
assistant
A septic tank is a small holding tank that collects and treats wastewater from a home or business. It is usually located on the property and connected to a drain field, which is an underground network of pipes that carry the wastewater away from the house. A sewer system is a larger infrastructure that carries wastewater to a treatment plant for processing before it is discharged into a river or lake.
