The source of water (rainwater collected onsite) rainwater collected onsite Precipitation collected at the district or regional scale is classified separately under 'stormwater.' is specified by the state as rainwater.

Technical basis

Georgia approves the onsite non-potable reuse of rainwater for automatic clothes washing, cooling tower makeup water and toilet and urinal flushing (Georgia DNR, 2012). All applicable provisions of the Clean Water Act (CWA) (33 U.S.C. §§ 1251 et seq.), including its implementing regulations, must be met in addition to any state water quality standards. For onsite non-potable reuse of rainwater, rainwater is required to pass through an approved filter system and undergo disinfection by an approved method that employs one or more disinfectants (see the table for more information). The technical basis for the rainwater filtration and disinfection requirements is not explicitly specified.

Types of onsite non-potable reuse approved for use in Georgia

Georgia DNR (2012) defines the following approved onsite non-potable reuse applications of rainwater: 

• Automatic clothes washing,
• Cooling tower makeup water,
• Toilet and urinal flushing.

Water reuse category/type

Georgia does not assign treated rainwater used for onsite non-potable reuse to a category or class.

Additional context and definitions

The respective treatment requirements for gray water and rainwater are briefly summarized for onsite non-potable reuse applications:

• Rainwater is required to pass through an approved filter system (downspout filter, leaf screen or strainer basket) and disinfected by an approved method that employs one or more disinfectants, such as chlorine, iodine, ozone or UV (Georgia DNR, 2012). Rainwater systems of less than 200-gallon capacity for outdoor non-potable applications normally do not need disinfection.
  • Rainwater is defined as “water collected from runoff of roofs of buildings or homes after a rain event” (Georgia DNR, 2012).
