Miami-Dade County developed a 20-year Water Use Efficiency Plan implementing strategies to promote water conservation to residents. These strategies include financial rebates promoting the use of high efficiency fixtures in homes and businesses and conducting outreach throughout the county educating residents on the importance of conserving water.

In addition, Miami-Dade County has enacted water use efficiency-legislation including permanent landscape irrigation restrictions, ordinances requiring Florida-Friendly landscaping in new construction and in right-of-ways, and the installation of high-efficiency plumbing fixtures in new construction.

What can you do to help? Take a shorter shower. Turn off the faucet when brushing your teeth and shaving. Install high-efficiency fixtures in your home. Think about your water use. These efforts will be effective in reducing your water use while developing a resilient water supply into the future mitigating the effects of saltwater intrusion.
