What's a septic system?


A septic system is an underground system put in place to treat and dispose of wastewater in locations where a typical central sewer system is not the most feasible option. Septic systems are often preferred when the homes or other buildings are close together and in rural regions. It is contained on-site, making it a very efficient method of wastewater disposal.
