Summary of Florida’s Water Reuse Guideline or Regulation for Rainwater Collected Onsite for Non-potable Water Reuse
This page is part of the EPA’s REUSExplorer tool, which summarizes the different state level regulations or guidelines for water reuse for a variety of sources and end-uses.
The source water for this summary is Rainwater Collected Onsite.

In Florida, onsite non-potable water reuse The use of treated onsite collected waters for non-potable purposes at the single-building or district scale. This reuse application excludes the use of recycled water from a centralized treatment and distribution system for landscape irrigation or commercial uses. applications include irrigation, car washing and toilet and urinal flushing (in some local jurisdictions), among others. The source of water rainwater collected onsite Precipitation collected at the district or regional scale is classified separately under 'stormwater.' is specified by the state as rainwater. The write-up uses state terms when discussing sources or uses of water that may differ from the Regulations and End-Use Specifications Explorer's (REUSExplorer's) terms.

State requirements for water quality and treatment are often associated with the source water. Florida has an onsite non-potable water reuse summary page where the source water is onsite collected waters.
Technical basis
Florida approves the onsite non-potable reuse of rainwater for landscape irrigation, vehicle washing, filling swimming pools and ornamental fountains and, in some jurisdictions, toilet and urinal flushing (Florida Plumbing Code, 2017). 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. Onsite non-potable water reuse systems using rainwater must contain no detectable fecal coliforms, enteroviruses, sodium or chlorine at the point of use. The technical basis for the derivation of pathogen and chemical removals for rainwater treated by non-potable rainwater collection and distribution systems is not explicitly specified.
Types of onsite non-potable reuse approved for use in Florida
University of Florida (2018) lists several approved onsite non-potable uses of rainwater, including:
- Irrigation of lawns and gardens,
- Car washing,
- Filling ponds, fountains and swimming pools,
- Toilet flushing (some local jurisdictions).
Water reuse category/type
Florida does not assign rainwater used for onsite non-potable reuse to a category or class.
Additional context and definitions
The respective treatment requirements for rainwater are briefly summarized for onsite non-potable reuse applications:
- Collected rainwater shall be filtered and disinfected as needed to ensure there are no detectable fecal coliforms, enteroviruses, sodium or chlorine per 100 mL at the point of use.
- Rainwater is defined as “water from natural precipitation collected only from above-ground impervious roofing surfaces constructed from approved materials that are “compatible with the collection surface and the rainwater quality for the desired end use” (Florida Plumbing Code, 2017). Collection of water from vehicular parking or pedestrian surfaces is prohibited except where the water is used exclusively for landscape irrigation.
