Water Woes: Technology as Teammate

I just returned from a late winter mountaineering trip to Durango, Colorado where snow abounds and the locale’s high-desert-arid ways were seasonally hidden from sight. And though my main focus was simply to make it off of the high peaks in one piece, I couldn’t help but aim my attention to the sheer amount of snow on the ground and, thus, the flowing rivers and creeks all around us. What a stark contrast to the thirsty low deserts of Arizona. And though we are regional neighbors, I suddenly felt what could only be described as an age-old territorial rivalry – that for the single most precious resource on earth –water.

So when I returned home, to the warm winter splendor of Tucson, I took note of all of the ways that the Sonoran Desert has prospered from one millennia to the next in the face of sustained climatic harshness. What struck me most, however, was the unfortunate human variable and just how much water we waste every single day in this place that has so little of it to spare.

Do we really need to leave the bathroom tap open and free-flowing while we brush our teeth?

To add to my already-burgeoning guilt regarding humanity’s lack of natural resource management, the industry in which I work is culpable for some of the most egregious water gaffes of all. Oftentimes, landscapes consume upwards of half of all household water. So what to do about it? Should we live in a world with bone dry and unsightly landscapes? Not at all. Do we need to get rid of grass and swimming pools all together? Definitely not. What really needs to happen is that we must recognize that it's the 21st century and technology is on our side. Smart irrigation controllers, systems that monitor water usage, efficient sprinkler systems, access to unique arid-adapted plant material, viable synthetic lawn alternatives and a profusion of water harvesting techniques are readily available and actually quite sophisticated.

Now if we could only convince the human race as a whole to catch up to those technological advances – imagine what magnificence could be realized.

Ideal Irrigation: The Secret to a Successful Watering System

The best way, I’ve found, to organize an irrigation system is to consider each type of plant being watered - a.k.a.: hydrozones.

Ask ten different landscapers how they would install a single irrigation system and you'll get ten different answers. So how is anyone supposed to know how to set up what is essentially, in the desert Southwest, the lifeblood of a landscape? Though it's probably easier to explain what not to do, the following is my number one tip to get you on your way to irrigation mastery.

Needless to say, an irrigation system in Tucson, Arizona is a completely different animal than one installed, say in the Midwest. Overhead watering, for anything other than lawns, is not a great idea. Dividing a system into spatial zones (e.g.: front yard, backyard, etc.) also creates problems. And differing plant types sharing the same watering system is wasteful and ill-advised (adjusting just the pressure compensating emitters only accounts for one of the necessary variables).  The best way, I’ve found, to organize an irrigation system is to consider each type of plant being watered - a.k.a.: hydrozones.

Trees. Shrubs. Cacti and succulents. A vegetable/herb garden. Potted plants. Citrus. Each category of plant material has very distinct water requirements. For example, trees will benefit from deep, infrequent watering while potted plants will want short bursts of moisture multiple times each day. This means that a separate valve assembly (including filter and pressure regulation) will be required for each plant grouping. Weekend Warriors can set this up themselves, though a licensed landscape or irrigation contractor is the safest bet. It’s really not that expensive an endeavor once the benefits come into focus. Just a little extra investment up front pays off in the end.

Faux Advantage: The Merits of a Synthetic Lawn

I have to admit that I’m not sure I’d want fake grass in my own backyard. But, in a recent twist of reason, I’ve started to warm up to the notion. Though I couldn’t imagine taking a midday nap in a meadow of green plastic fibers, there are applications that warrant its use. And, no, I’m not talking about a sports field (though that is a worthy usage). If we are serious about cutting our resource consumption…then maybe synthetic lawns deserve a closer, and less disapproving, look.

Though synthetic grass can be applied in pretty much any residential setting, it would be best put to use in commercial properties. Not so much at parks and schools where people actively interact with the material, but more like strip malls, shopping centers and office complexes. These are areas that inevitably have lawns that are completely under-utilized and over-maintained. No one is having a picnic or rolling around with a lover at any of these locations. Grass is there because it’s green.

But consider the costs. Weekly mowing. Daily watering. Monthly fertilizing. Seasonal over-seeding. Output of fossil fuel emissions. And much of the time the grass looks like hell. Enter synthetic lawns. With a preemptive and initial outlay of money, all of these property management woes disappear. Lawn sprinkler leaks become a thing of the past. Irrigation over-spray on sidewalks is gone forever. Water bills and maintenance costs plummet! And the business property owner is left with a landscape that looks good all year-round.

Synthetic turf companies have even made huge advances in the overall appearance of their product. No longer do fake lawns look like Easter egg basket filler. You can now find faux grass varieties with what looks to be natural imperfections and spent blades and most are made of recycled plastics. Now don’t you think that’s worth at least a second glance?
