Drought and Surplus: Adventures in Water-Use with Morgan Hopkins

Few people were more excited than me when Morgan Hopkins was hired as Florida Yards and Neighborhoods agent at Miami-Dade County Extension. This program includes the irrigation outfit wherein I learned everything I know about irrigation tech and media work. Ms. Hopkins was eminently qualified and the right person at the right time for that program. Life being what it is, however, she is now following other opportunities west. As a water-use expert working in one of the two high-profile, IFAS-affiliated irrigation rebate programs in Florida, Ms. Hopkins agreed to share exiting insights with IrriGator.
Water-use expert Morgan Hopkins
You joined the irrigation program at Miami-Dade Extension fresh from graduate school. What drew you to Miami-Dade?
MH: I had a really great experience as an undergraduate working with Oklahoma’s Cooperative Extension Service and working with Oklahoma City developing their water conservation program. Having the opportunity to continue in a career where I’m able to educate residents on outdoor water conservation, this was something too good to pass up. I was able to get a taste of how important that was in Oklahoma. I thought it would be great to be able to continue this with the University of Florida. Then realizing how strong the extension network was made it even more attractive.

The only hesitation for me was the intimidation of learning a completely different environment as far as plant material goes, and then actually tackling water conservation in an area that typically gets a surplus of water. The size of Miami didn’t really intimidate me. In my mind I thought “well, great that’s just more people to reach and to educate,” instead of seeing it as more work. For me it was about how am I going to frame water conservation in an area that typically gets plenty of rainfall and has access to quite a bit of water?

What are the challenges of managing a large-scale water program in an urban center like Miami-Dade?
MH: One of the challenges: when we met with homeowners one of the common things we heard is “I’m on a well, I don’t really need to save water.”  That disconnect of the water situation in South Florida was really something that we had to educate more people on. That kind of surprised me. I figured with sea level rise and the Biscayne aquifer and salt-water intrusion that people might be more aware of these things. But again that was just another educational opportunity that we were able to take advantage of when talking with homeowners.


The fact that Miami-Dade is one of the southernmost regions in Florida and having that recognition of UF/IFAS is definitely a challenge for us. People often confuse us with FIU and they aren’t really sure why UF is down here. We don’t have the recognition that a lot of other counties have that are closer, or have a stronger connection, to Gainesville. People kind of favor the hometown universities here and kind of see us as an outsider. That’s a challenge we face in having credibility in some areas.

What are some opportunities that you feel you only scratched the surface on, that the program and your successor can build on?
MH: One of the things that I really wanted to tackle was getting out in the community more and doing more workshops - whether it was with Florida-Friendly Landscaping or irrigation. Irrigation is never sexy but I did want to try to make that effort whether it was with industry or with homeowners – try to make irrigation more digestible on a basic level, for people to understand the relationship of plants and water and the connection to our South Florida ecosystem. Having workshops based on those topics is something I would like to have done more.

Also, I really wanted to strengthen our reporting and our evaluations for the irrigation program and really do more technical work behind those – calculating water saving and sharpening the tools that we already have and the things that we’re already doing to take them to the next level. I know that as it continues on those things will come to life with my successor.


I understand you’re headed west. What are you most excited about or looking forward to in this next chapter of your career?
MH: It’s a bittersweet move because I’ve really enjoyed my time with UF/IFAS; it’s such a great organization and it has an immense amount of resources that other extension services are not fortunate to have. But I am excited. I started my water conservation career in a drought-stricken state. Oklahoma was in a five year drought when I started my masters. I am excited to get back to a region more prone to drought, where people are more in tune with water conservation. Scarcity really seems to make a stronger impact on the way people think about water and the way they use it and how it’s managed and how we educate citizens on water conservation, especially in the landscape.

Applying science to water savings: smart irrigation month 2014

In late June I had the opportunity to join Miami-Dade’s Urban Conservation Unit (U.C.U.) for a day in the field visiting properties participating in Miami-Dade County’s Irrigation Rebate Program.

Front yard turf zone, circa 2011
Playing the classics
The final visit for the day was a home in Coral Gables, the City Beautiful. In 2011, this residence had rehabilitated its potable water irrigation system and installed a weather-based irrigation controller (WBIC). With a landscape that features mostly palms, shrubs and decorative stones, a seven zone irrigation system has no business at this location. In any case, the controller installation was rebated in 2011 and the homeowner asked the team to stop by to see if things were still on the up and up.

No longer on the up and up: Jesus Lomeli and a riser nozzle gone missing
A bit about WBICs
Once we realized where we were, U.C.U. tech Jesus and I had eyes big as saucers. Why? Two words: applied science. Weather-based irrigation controllers require very specific programming for each zone:
  • soil type
  • plant type
  • shade factor
  • sprinkler head type, etc.
All those factors are churning away in this little guy right here
The WBIC model at this location uses these factors along with weather data from an on-site weather sensor/tipping bucket rain gauge to calculate evapotranspiration (or ET). This ET value is then used to generate run times for each zone. When a landscape is designed with hydrozones in mind, much like this one with one turf zone and six tree or shrub zones, a weather-based controller can really work its magic.

Weather sensor: perfectly located and busy doing science 
So after a quick zone by zone wet-check to look for breaks or other problems, we dove into the controller’s “history” feature to track the watering events by date starting from January of this year.

Smart irrigation month is an industry-fostered construct that promotes outdoor water-use efficiency during the month of July, the outdoor water-use peak in the calendar year. The Irrigation Association recommends a plethora of practices from design to technology that, if implemented, can reduce water-use while still maintaining a healthy landscape.

Tree canopy shade is real: front yard turf zone in 2014
Better living through tech
In the best of all possible worlds the property I'm discussing here would have no (or temporary) irrigation. There would be a colorful Florida-friendly groundcover in the shady front area, and all the remaining ornamental areas would continue to live off rain alone. 

Back yard rocky expanse: wait, what...
In this world, however, the weather-based controller was expertly managing water-use for this landscape – irrigating the lone turf zone regularly, and watering the other zones once a month, or once every few months. During especially rainy stretches, the system would not run for weeks. 

Some water-wise options from Ewing Irrigation
The takeaway
There is definitely room for improvement at this location - namely low-volume irrigation in the six tree/shrub zones - but the best decision this homeowner ever made for the landscape (and water bill) was installing a WBIC three years ago. This wasn't the first time Jesus and I had seen a weather-based controller save water this way, but it's the most recent, and on the cusp of smart irrigation month 2014, all the sweeter.

Saving water...and winning awards

Around this time last month I had the opportunity to attend a Florida-Friendly Landscaping (FFL) in-service training (IST) in Gainesville. The event attracted many agents and master gardeners from across the state, and provided me a chance for some team-time with Miami-Dade County’s Urban Conservation Unit (UCU).

Miami-Dade County's FYN/UCU team: Jesus Lomeli and Laura Vasquez
The Miami model
Miami-Dade County’s FFL/UCU program is a Water and Sewer Department-funded entity that works within the UF/IFAS Cooperative Extension Office, promoting the FFL ethic for sustainability (via the nine principles and yard certifications) while also executing the county’s larger goal of water-use efficiency through incentive-based urban landscape irrigation retrofits and a rain barrel program.

During the IST’s strategizing session, many of the Extension agents in attendance commented that this is a different approach to the usual county FFL program structure. Is it a model that can be replicated in other counties, even at a smaller scale? There certainly are non-replicatable advantages to working in a large urban center where the water utility is under constant pressure to meet water conservation goals and is prepared to invest resources accordingly.

Removing irrigation and installing Florida-Friendly
plants is rebate-worthy in Miami-Dade 
How it works
What I find most effective about the program is that although there are three areas of focus, each one complements all the others. The rain barrel program promotes low-intensity rainwater harvesting and maintains a presence year-round with workshops throughout the county and regular teaching events with children in schools. 

Do you know the nine principles?
The FFL program consistently certifies yards as Florida-Friendly based on the nine principles (above) and sometimes consults with landscape architects integrating FFL into initial designs on new construction. And the irrigation rebate program is in the field almost daily assessing residential and large systems and making recommendations to improve efficiency, all of which also qualify for rebates. At every point of contact with the community, each area of focus promotes the others.

Thanks to the UCU and forward-thinking contractors, weather-based
irrigation timers like this one have a foothold in Miami-Dade
2014 NACo Achievement Award
This month the National Association of Counties awarded Miami-Dade’s FYN/UCU program with an achievement award in the category of Environmental Protection and Energy, one of only 24 programs recognized across the U.S. 

This is well-deserved recognition and I’m pleased to play a role in this team’s efforts for sustainability and conservation in South Florida.
