To save water, irrigate less


Growing up, we are taught to save water by turning the faucet off while we brush our teeth or by taking short showers instead of baths. Every bit of saved water is important, but recent research indicates that water use in our yards can really move the needle.

“Florida is facing a water crisis, and we all have a part to play in protecting our state’s water,” said Nick Taylor, UF/IFAS state specialized Extension agent and leader of H2OSAV, the program that led the study. “The work we do indoors to reduce water use is important, but what can make the greatest difference is changing how we water our landscapes.”

Previous research by UF/IFAS found that the highest water users spend 60 to 70% of their total water use on their yards. Many homes in Florida do not have an irrigation system. For those that do, reducing outdoor water use is the key to making truly impactful steps towards water conservation.

This study analyzed data from more than 1 million homes across nine Florida counties. They found that the average home with an irrigation system uses at least 991 gallons of water each time they water their lawn. This is equivalent to showering for more than eight hours, doing 37 loads of laundry in a high-efficiency washing machine, or running the dishwasher 50 times.

“We want to help people understand the magnitude of water used for a single irrigation event,” said Taylor. “Often, people are overwatering their lawns, so skipping irrigation events is a good place to start.”

Here are some tips and resources to reduce outdoor water use and still maintain outdoor spaces you and your family can enjoy.

  • Only water your landscape when it needs it. Many people are overwatering their lawns, which increases weeds, reduces drought tolerance, and, of course, wastes water.
  • Make sure you have a working rain sensor device -- it’s the law! If you want to go a step further, you can install a smart irrigation device that helps your lawn get the right amount of water. Check your local utility to see if they offer a rebate or free irrigation audits. 
  • Always check local watering restrictions before turning on the sprinklers. This scheduler is a helpful tool for making watering decisions.
  • Consider reducing your landscape’s irrigation needs. Install no or low-water use landscape beds with drought-tolerant plants. The Florida-Friendly Landscaping™ plant guide can help you select the right plants for your landscape that require less water.
  • Contact your local UF/IFAS Extension office for guidance. Extension agents in all 67 counties are available to help you reduce your water use and care for your yard.

    Wish we’d move away from grass lawns altogether. Imagine the amount of water the world would save if we didn’t have to maintain lawns. Ban grass lawns.
