Smart Irrigation and Urban Transformation: A Conversation with Justin Nichols

As someone who regularly engages with irrigation and water management professionals, OptConnect’s Justin Nichols understands the critical nature of water conservation, particularly in an urban landscape. We sat down with Justin to discuss the need for sophisticated, smart irrigation systems to help maintain green spaces in cities.

Justin, you interact with smart irrigation professionals all the time. What are you learning about the industry?

First off, the irrigation needs of today are different than yesterday. Water is limited and is our most precious resource. A lot of great minds are coming up with more efficient ways to maintain all those expansive golf courses, city parks, and urban green spaces.

On the one hand, we need all those spaces to maintain our physical and mental wellbeing – but it takes really intelligent planning and monitoring to use water wisely and efficiently. The old irrigation methods tend to be inefficient. That’s why smart irrigation systems were invented. At OptConnect, we’re passionate about providing cutting-edge connectivity solutions to those systems. so they can operate the way they were designed to.

Why is smart irrigation necessary?

Many irrigation methods and systems are outdated. In every cityscape, there are green spaces that are being overwatered or underwatered. It’s just imprecise, especially in an era where water conservation is increasingly urgent. When water is wasted, that also impacts city budgets. It’s bad for the environment and the bottom line.

Luckily, smart irrigation optimizes water usage, reduces costs, and contributes to healthier green spaces. Everybody wins.

Typically, what goes into smart irrigation systems?

Great question. Typically today’s smart irrigation systems should at minimum include soil moisture sensors, weather stations, and smart controllers.

1. Soil Sensors

There are many types of soil moisture sensors available today that are more affordable and adaptable to work across multiple irrigation controller platforms.

As the name implies, soil moisture sensors measure the water content in the soil. These sensors provide critical information for many different applications, including those that:

Monitor soil water content
Optimize irrigation
Prevent overwatering and underwatering
Support research
Perform general environmental monitoring

Each smart irrigation system should use these sensors as essential tools for efficient water management.

2. Weather Stations

Secondly, each system should use weather stations to prevent unnecessary watering, by integrating real-time weather data (precipitation, humidity, and wind) into the schedule. We’ve all seen plenty of sprinkler systems operating during a rain or wind storm. The weather station prevents that from happening and shifts the irrigation schedule to operate in drier conditions. Many new smart irrigation controllers have this technology built in.

The weather station integrates several key points of data into the irrigation schedule while allowing for manual adjustments. Here’s how it works:

The station uses rain gauges to measure rainfall and send that data to the irrigation system.
The weather station works with the soil monitors to prevent unnecessary watering.
Each station also collects evaporation data to help plants replenish whatever water they lose.
Temperature and humidity are also tracked to fine tune the irrigation schedule.
Because wind impacts evaporation rates and water distribution, the station also tracks wind speed and direction.
Just like a meteorologist, the station forecasts rain so the system can prevent watering just before a storm hits.

3. Smart Controllers

Finally, a smart controller is the brain of the irrigation system. While manual adjustments are still possible, the controller will automatically adjust watering schedules and ensure water conservation. Of course, even the smartest controllers can’t do anything without a reliable connection. At OptConnect, we provide cellular connectivity solutions for irrigation so that everything works seamlessly and reliably. to those controllers so everything works together seamlessly and continuously.

Get Started

What kinds of applications do you see in urban landscapes?

We’re starting to see a lot more smart irrigation applications in urban environments. Community parks are increasingly able to maintain healthy green spaces even while conserving water and improving their irrigation efficiency. All visitors notice is the beauty and healthy benefits. Smart irrigation is beneficial to all parties.

Community gardens and botanical areas are capitalizing on smart irrigation, too. That might look like a precise watering routine in which a certain plant gets more water while another needs less. Everything is tailored to the needs of the plant life in each area.

Golf courses generally have a reputation for using a lot of water. But as more owners get smart about irrigation, they can keep their greens beautiful without high costs and even higher water usage.

We also see more innovations like green roofs, where designers tap into a long list of environmental benefits – including minimizing urban heat islands and creating more efficient stormwater systems. But the plant life on those rooftops needs special treatment. Smart irrigation helps maintain just the right level of moisture so as not to damage the building’s structure. Just as important, it keeps plants thriving.

What are the main challenges to smart irrigation?

Well, there are several. Sometimes, it’s a technological issue. For instance, sensors may not always be accurate. Or networks will go down. Connectivity in general might not be fully reliable outdoors. Maybe the issue is financial: creating and maintaining a system might not be the top budget priority.

In addition, water use regulations can vary, which definitely adds complexity to the process. Or maybe an organization just doesn’t have personnel to spare on new initiatives.

So, what’s the best way to resolve these issues?

In the case of technology challenges, the good news is that technology is always improving. Devices are becoming much more reliable. Certainly in terms of connectivity, there are many safeguards now in place that can help smart irrigation systems stay connected.

About the financial considerations: While it’s true that an initial investment can be challenge, it helps to think long term. Over time, a smart system will save water usage and maintenance costs many times over. Plus, there are incentives and programs that exist to help offset costs for municipalities, homeowners, and other organizations considering smart irrigation initiatives.

As for overcoming regulatory hurdles, that’s also a work in progress. Policymakers should be at the forefront of supporting smart irrigation and helping more organizations and cities adopt it. Stakeholders, such as those in the Irrigation Association, actively advocate for their members. They conduct yearly fly-ins to Washington, D.C. to meet with key decision makers and influence policy and priorities. Once the cost benefits of smart irrigation are fully understood, there’s a much greater likelihood that these systems will be advocated for within their communities.

Which future trends are most important for this industry?

Smart city initiatives are becoming more prevalent. But beyond any one trend, it’s more about broader awareness about the benefits of smart irrigation. Again, water is a critical resource that nobody can afford to take for granted. That’s especially true for areas in the Western U.S., but it’s an issue in many other areas as well.

As more stakeholders see the importance of smart irrigation technology, it’s a given that implementation will increase. When that happens, urban areas can lead the charge toward greater sustainability and efficiency. At OptConnect, we’re proud to be a part of this important effort.
