20-Year Water Use Permit

The Water Use Permit is a plan for meeting the present and future water needs of the County while protecting natural resources such as the Everglades. This is where you can find information related to Miami-Dade County's 20-Year Water Use Permit, re-issued on Feb. 9, 2015  (35 MB) and modified on Sept. 21, 2015  (549 KB) by the South Florida Water Management District Governing Board.

Alternative Water Supply Sources

The Water Use Permit requires WASD to develop alternative water supply sources and continue with its Water-Use Efficiency Program. The Permit ensures water will be available for Miami-Dade County's needs and lays the groundwork for very ambitious capital improvements over the next two decades.

1. Floridan Aquifer As An Alternative Water Supply
The brackish Floridan Aquifer is located much deeper underground than the Biscayne Aquifer (which has historically supplied all of Miami-Dade County’s drinking water) and is brackish or salty. In order to be able to use this water, it will have to undergo a more expensive and time-consuming treatment process.

Hialeah Reverse Osmosis plant
(Completed in 2013)
Reverse Osmosis is one of the most rigorous treatment processes available, similar to a screen door with microscopic openings. The brackish Floridan Aquifer water is pushed through this “screen” with enormous power and pressure, thus eliminating a very high percentage of contaminants.

South Miami Heights Water Treatment Plant
(Current WUP Implementation Date: 2019)
The brackish Floridan Aquifer will supply some of the water that will be treated in the same way as the Hialeah Reverse Osmosis Plant.

2. A Comprehensive Water-Use Efficiency Program
Will provide cumulative savings of 19.6 million gallons per day over the next 20 years, based on the Florida Department of Environmental Protection’s “Conserve Florida” Program Savings will be realized through the implementation of best management practices that include incentives and promote high efficiency technology
for indoor and outdoor water use.

  • High-Efficiency Toilet Rebate Program
  • High-Efficiency Toilet Full Retrofit Program
  • High-Efficiency Clothes Washer Rebate
  • Water-Efficient Landscape and Irrigation Evaluation
  • Showerhead Exchange and Retrofit Programs
  • Green Lodging and Restaurant Program
  • WET in the City School Education Program

3. Water Loss Reduction Program
WASD’s Water Loss Reduction Program is expected to produce water savings of 14.25 MGD over the next 20 years. It includes the following components:

  • Enhancement of the award-winning distribution system Leak Detection Program
  • Comparative accuracy testing on supply well meters
  • Comparative accuracy testing on wholesale customer supply meters
  • Evaluation of Automated Meter Reading (AMR) with leak monitoring
  • Performing a system-wide water audit
  • Inventory and reduce unmetered supply
  • Conduct field accuracy testing for selected commercial and industrial meters
