The Loudoun County Health Department sent out letters in March 2012 to the 1,400 plus owners of alternative septic systems advising them that they are required to have their system inspected no later than July 1 of each year.
The Loudoun County Ordinance Chapter 1067 - Ordinance to Regulate the Establishment, Operation, and Maintenance of Alternative On-site Sewage Disposal Systems
established requirements for operation, maintenance, and inspection of these alternative septic systems.This ordinance was revised in April 2013. The revisions, which have been adopted by the Board of Supervisors, but not yet codified, are online here
Examples of alternative systems by some of their colloquial names are:
- Aerobic treatment unit (ATU)
- Drip distribution
- Low pressure distribution (LPD)
- Peat filters
- Sand filters
- Spray irrigation
Manufactures names, include:

If you have one of these systems, it is most likely that you have a alternative system and if you did not receive a letter from the Health Department, you should call the department at 703-777-0234.
