Septic Systems

Septic SystemsWhen public sewer is not available, a septic system may be installed with the approval from Fairfax County Division of Environmental Health. For more information on septic systems, please visit the Division of Environmental Health website or call them at 703-246-2201, TTY 711.

Homeowners whose septic systems are failing, and deemed non-repairable by the Division of Environmental Health, will be required to connect to sewer if the property is within 300 feet of available public sanitary sewer.

For failing septic systems where sanitary sewer is not available, property owners should contact the Division of Environmental Health for available alternatives.  

All outhouses in use today in Fairfax County have been grandfathered. All new construction will be required to have a sewage disposal system that is approved under the current codes.
