What is an Onsite Wastewater Treatment System?

An onsite wastewater treatment (septic) system is used in areas without access to municipal sewer lines. They are typically installed in rural or suburban homes and businesses, and use a combination of natural and technological processes to treat wastewater from bathrooms, showers, kitchen drains and laundry. The system works by separating solid waste from the liquid when the solids settle in the septic tank. The liquid then passes through a series of pipes and chambers where it is filtered/treated and released into a drain field | View Example >

Onsite wastewater treatment systems are also called:

  • Septic systems
  • Conventional septic systems
  • Decentralized wastewater treatment systems
  • Cluster systems
  • Individual sewage disposal systems
  • Private sewage systems
  • Alternative treatment systems

Proper installation and maintenance, including regular inspections, are important to ensure the system functions efficiently, protects public health and the environment, and preserves valuable water resources.
