Here’s Why You Can’t Turn On Your Twin Falls Sprinklers

Here’s Why Your Twin Falls Sprinklers Aren’t Turning On Yet

With sunny days this week and highs near 80 degrees on Wednesday, it might feel like the perfect time to fire up your sprinkler system. But if you’ve tried—and failed—to get your sprinklers running in a newer Twin Falls neighborhood, you’re not alone.

Here’s why that’s happening.

Many Twin Falls Subdivisions Run on Pressurized Irrigation

If you live in a neighborhood built within the last 15 years or so, there’s a good chance your irrigation system runs on pressurized irrigation—not regular city water.

That means your sprinklers don’t pull from your home’s water line. They use water from nearby canals, which is stored in retention ponds and then pumped through pressurized stations to reach your yard.

Here's the Catch: Those Stations Aren’t On Yet

The Twin Falls Canal Company is responsible for clearing and charging the system each spring. Until they flip the switch, water won’t flow through your sprinkler lines. Usually, that doesn’t happen until mid-April, depending on water availability and forecasts.

What If Your Home Uses City Water?

If your system runs on standard city water, you can turn it on now—just be careful. Twin Falls isn’t out of the woods for freezing temperatures just yet, and running your system too early could result in frozen or burst pipes.

It's a good idea to keep an eye on the forecast and wait until overnight temps are consistently above freezing before turning on your system.

A Simple Workaround

Still want to green up your lawn in the meantime? You can always hook up a hose to a portable sprinkler and water manually until your system is ready—or until you're ready to risk turning it on.
