Upgrade Your Irrigation. Conserve Water. Save Money

Houston Public Works is partnering with Rachio to offer homeowners an easy way to save water and money with a smart irrigation controller. This device connects to your existing sprinkler system and adjusts watering automatically based on Houston’s weather, soil type, and landscape needs.

Unlike traditional timers that water on a fixed schedule, smart irrigation controllers make dynamic changes—skipping watering when it rains, adjusting for temperature changes, and even adapting to different zones in your yard. You can control it all from your smartphone or computer, anytime, anywhere.

It’s a simple way to take the guesswork out of watering and keep your landscape healthy while using less water.

Why It Matters

With Houston’s hot, unpredictable climate, smart controllers make it easy to conserve water while keeping your yard healthy.
