If you live in California, like I do, you shouldn’t be watering your lawn at all. However, if we ever make it past this drought (assuming it doesn’t launch us into a Fallout-type post-apocalyptic wasteland) and it becomes okay to water your lawn again, you need to be smart about it.

Or at least your sprinklers need to be smart about it.

Back when water was plentiful, it was easy to over-water your lawn, which is not only wasteful of water (and helped get us into this mess in the first place) but it’s also not great for your lawn. A company called ETwater has the solution: a smart sprinkler that only waters your lawn when your lawn actually needs it.

The sprinker system works by analyzing not only local data but also weather data, delivering less water if it’s been raining. It will also adjusts its output based on what type of soil you have and what sort of plants you’re looking to water, even compensating for water runoff based on the slope of the landscape you’re watering.

It’s a great idea and ETwater says it can cut your water consumption in half. Check out their website if you’re interested in purchasing the system.
