Every July, the irrigation industry celebrates Smart Irrigation Month — a national awareness campaign dedicated to promoting the efficient use of water outdoors. It’s a great time to take a closer look at your own irrigation system and ask an honest question: is it working as efficiently as it could be?
For Minnesota homeowners, the answer is often no — and the good news is that fixing it is easier than you might think.
The Story Behind Smart Irrigation Month
Smart Irrigation Month was established by the Irrigation Association, the leading professional organization for the irrigation industry in North America. The campaign runs every July — right in the heart of peak watering season — to raise awareness about how much water is used and wasted on residential and commercial landscapes every summer.
According to the EPA, landscape irrigation accounts for nearly one-third of all residential water use in the United States, totaling nearly 9 billion gallons per day. Roughly 50% of that water is wasted due to evaporation, wind, overwatering, and inefficient systems.
That’s a staggering amount of water — and money — going down the drain every single day.
What Does “Smart Irrigation” Actually Mean?
Smart irrigation is about using technology and best practices to apply the right amount of water, in the right place, at the right time. It’s not just about buying a fancy controller — it’s a whole-system approach that includes:
- Weather-based smart controllers that automatically adjust watering schedules based on local conditions
- Rain and soil moisture sensors that prevent your system from running when the ground is already wet
- Properly designed systems with matched precipitation rates and correct head spacing
- Low-volume drip and micro-irrigation for garden beds and containers
- Regular system audits to catch leaks, broken heads, and inefficient zones
Any one of these improvements can make a meaningful difference. Together, they can transform an outdated, wasteful system into one that keeps your landscape beautiful while cutting water use dramatically.
Why This Matters Especially in Minnesota
Minnesota might not seem like a place that needs to worry about water conservation — we have over 10,000 lakes, after all. But water conservation matters here for reasons beyond just supply:
Your water bill. Municipal water rates in the Twin Cities and surrounding communities continue to rise. Wasting water through an inefficient irrigation system isn’t just an environmental issue — it hits your wallet every month from May through October.
Our lakes and waterways. Overwatering leads to runoff, which carries fertilizers, pesticides, and sediment into storm drains and eventually into Minnesota’s lakes, rivers, and streams. Watering efficiently is one of the simplest things homeowners can do to protect local water quality.
Minnesota’s variable summer weather. We can go from a week of soaking rain to a 10-day drought stretch without much warning. A traditional time-clock irrigation system doesn’t know the difference — it runs on schedule regardless of what the weather is doing. A smart system adjusts automatically.
Is Your System Smarter Than a 2005 Minivan?
Here’s a fun way to think about it. The average American car from 20 years ago had no backup camera, no lane assist, no Bluetooth, and got significantly worse fuel economy than today’s models. A lot of irrigation controllers in Minnesota yards are about that old — and just as outdated.
If your controller has a dial, a basic LCD screen, and no connection to the internet or weather data, it’s a time clock. It runs on a fixed schedule you set once and rarely changes. The system has no idea if it rained three inches last Tuesday. It doesn’t know that temperatures dropped and your lawn needs half as much water this week. It just runs.
Upgrading to a smart controller is the single biggest improvement most homeowners can make to their irrigation efficiency — and July, Smart Irrigation Month, is the perfect time to do it.
What Can Minnesota Homeowners Do Right Now?
You don’t have to overhaul your entire system to start making a difference. Here are a few simple steps to celebrate Smart Irrigation Month the right way:
- Check your controller. When did you last update your schedule? Is it still set to the program you put in three summers ago? At minimum, make sure your run times and frequency reflect current conditions.
- Walk your system. Run each zone manually and watch for broken heads, clogged nozzles, heads spraying pavement, or areas that are clearly over- or under-watered.
- Install a rain sensor if you don’t already have one. It’s one of the lowest-cost, highest-impact upgrades available — and it’s required on all new irrigation systems installed in Minnesota.
- Schedule a system audit. A certified irrigation professional can evaluate your system’s efficiency, measure actual precipitation rates, and identify waste you’d never spot on your own.
- Ask about smart controller options. There are excellent options at a range of price points, and many are simple retrofits to your existing system.
