How To Water In This Central Texas Drought

The Waco area has a lot of clay soil.  But, oddly enough, if you don’t have clay, you probably have sand.  Two completely different soil types.

But you water them the same.

Really. 

This is the story of a root.  That’s right, the root of a blade of grass in your yard right now.  Your roots live in the “root zone”––about 4 inches below the surface of the soil.  That 4-inch depth is the target for all water if your precious root is going to get a drink. 

Let’s look at what happens when you water.  If you have Sandy soil, the water soaks in readily. So readily, in fact, that the water passes your root as it is traveling merrily to the center of the earth. The end result is your root misses the water.

On the other hand, if you have clay soil, the water can’t penetrate down to the root zone, so it stays on top in the form of runoff. Again, your root doesn’t get the benefit of the moisture.

There’s a simple solution to both scenarios.

If your normal watering routine was 20 min. three times a week for spray zones and one hour, three times a week for rotor zones, consider dividing that watering schedule into smaller doses and do them more often.

Your spray zones were getting 60 min. of water per week, so try dividing that time into multiple waterings every day. If you watered 4 min. on each spray zone, but you did it twice a day, everyday, you would be using the same amount of water and you would be cooperating with soil type.  The water would have time to penetrate your clay soil down to the desired 4 inches in clay soil, and you would put so much water on that it ran down the curb.  The same goes for sandy soil.  The smaller dose easily travels to the root zone, but that’s all.  There’s not the flood of water that forces it past your roots.

This advice is counter from the wisdom you’ll get on TV, but that’s because we are not blessed with loamy soil with 85 degree maximum temperatures.  Don't worry, though.  I heard we're supposed to get a cold front . . . sometime in October!

It's Something Like a Traffic Accident

We had gotten off to a later start than intended so, when I saw the emergency lights ahead of us on I35, I groaned inside.  We were doing some work for a WalMart in Austin and we’re always conscious of the time because it takes a while to get there and get back. 

As it turned out, there was an accident but it was on the other side of the interstate.  A truck had completely blocked traffic and cars were backed up as far as we could see.  I was ashamed of myself for thinking I was glad it was “them” and not “us.”  We headed along our merry way for several minutes when I realized the traffic was still stopped.  It had been MILES.  Finally, we came to the end of the pack with new cars just now having to break to a halt.  

Because of my vantage point, I could see something they couldn’t.   Something inside me wanted to jump out of the car and yell, “Stop!  Get off the road!  Go eat, shop, ANYTHING!  You are going to be stopped here for HOURS if you don’t do something now!”

I didn’t, of course.

We continued down the road thinking about those poor travelers and how fortunate we were to not have been involved.  

It may seem to be an obtuse shift, but can we talk about water?  I believe we are in the same place as those unfortunate travelers.  By that, I mean there are already conditions in place that mask themselves now but will become imminently clear later.  

Think about it.  We have no less water now than we did on the day of Creation.  The issue is location, timing and purity.   This blog isn’t the forum to inform you on details, but I would hope you will be enlightened enough to start paying attention to how you use and waste water.  

We know a substantial portion of the water you use is outside (some say 70%).  So, if you are going to have a real impact on your water use, it probably isn’t going to be with a low-flow shower head--although that helps, too.  

That’s why we have a mission her at Rainstat Irrigation.  We want you to use all the water you need, and not a drop more.

We want to help you become a conservation hero while saving you money on your water bill.  Our Smart Controller for your sprinkler system saves anywhere from 20% to 50% on your water bill.  

Please call me.  My cell number is 254/744-1724.  You may be surprised at what you can do.  And if we all do our little part . . . 

Are We Running Out of Water?

You can hardly move around in this world without hearing about the water crisis.  "In the 20th century, we went to war over oil.  In the 21st century, we will go to war over water."  Really?  Before we go further, know that I'm biased.  I believe that governments and news media have a propensity to attempt to keep everyone scared.   It's like everyone graduated from the Chicken Little School of Outlook.  I am reading this book, Unquenchable - America's Water Crisis and What To Do About It, with my own set of filters that are ready to reject Robert Glennon's premise out of hand.

So why are we "running out" of water, and why should we care?   We have exactly the same amount of water today that we did at creation.  Remember Einstein's "matter is neither created nor destroyed"?  What then, is the problem?

First, we have more people.  

Second, we are fouling our own nests by our cavalier handling of fresh water.   Most of our water is saline and, therefore, undrinkable.  A look at our surface fresh water is telling.  The Great Lakes own 95% of fresh water in the US.  It would be an understatement to say these lakes are big.  But, if you want to see what can happen when you mix big bodies of water with bad decisions, all you have to do is look at the former USSR and the Aral Sea.  This was the world's fourth-largest inland body of water.  Today, it has lost 90% of it's water.  It all started by diverting fresh water that flowed into it for "good" but short-sighted purposes.  

If we continue to write checks without deposits to at least equal the withdrawals, we end up with no money.   All of life needs water to continue living.  We will run out, however, if we use too much.  We can't supply more water, so the role of the steward is becoming more important.  

We see a small role here.  

We believe we can help ensure that the the water you use is not wasted. 

Thanks for your interest.  More and more, I believe this is going to be of interest to us all.

Waco Changes Code–Lemons or Lemonade?

Most people don't know about it yet, but the City of Waco made a change that affects just about everyone who owns a sprinkler system. Any way you look at it, it's going to add additional cost to the citizens. Bummer. This cloud, however, may have a silver lining. (The good news is at the bottom of this post.)

First, what changed?

Your yard is now classified as a "high hazard" from the folks that sell you your water. You have always had to have a backflow device as a part of your sprinkler system (to protect other folks that use water from the city), but now you must have a Reduced Pressure Zone (RPZ) backflow device. Because it is engineered so that it cannot fail without obvious signs, it is considered the most full-proof device--except for air-gap, and we won't get into that here.

But, I'm "grandfathered in," aren't I?

Well, sort of. You don't have to go out right now and update your system to code, but you will eventually have to. By "eventually," I mean, we cannot bring your system back into service without bringing it up to code if we do a "major repair." A "major repair" is defined by the state as any repair that opens your system's main line to the atmosphere. Obviously, that means we can't repair your existing backflow device without bringing it up to code. But, it also means we can't even repair a valve without this update.

How much, you might ask, does this cost?

I'm not quoting prices here because we need information specific to your system. We need to know what you have now and what size RPZ you need. Brace yourself, though, 'cause it's not cheap. The RPZ itself is a fairly large bronze apparatus. And, the upgrade of the backflow device isn't the only thing that is required. Your system now requires a valve that isolates the sprinkler system from the rest of your domestic water supply. You may already have this, and, if you don't, you should. A filter must be installed, too.

So, this new rule means you will eventually upgrade your sprinkler system to include a Reduced Pressure Zone (RPZ) backflow device, a filter and an isolation valve.

Does this sound like it's all Lemons and no Lemonade?

Now for the good part:

By upgrading to an RPZ, you can do some fun stuff with your sprinkler system you have probably wondered why it's not done all the time. Like fertilizing or getting rid of mosquitos. Injecting stuff into your sprinkler system is the perfect way to distribute anything that goes on your lawn. It couldn't be done before because your old backflow device would not adequately protect the water supply. Well, now it does!

Fertilize

Now, fertilizing is as easy as adding a water soluble fertilizer (a lot of choices--including organic) to a tank. It dispenses a very small amount of fertilizer to your system every time you water. Is that too much fertilizer? No. Our most popular system, when set at its highest output is 400 parts water to 1 part fertilizer. At it lowest setting, it is 37 times less fertilizer than that. And, because of the way it is applied, it is much, much more beneficial to the plants than throwing fertilizer granules on the ground and watering them in.

Mosquitos

Once you have a system for distributing a solution through your sprinkler system, a lot of possibilities open up. Want to cook out, but he mosquitos are carrying you away? Add some organic insect repellant, run through a short cycle and viola! you have re-occupied your back yard.

So, the painful part is updating your sprinkler system to meet the city's new code. That's the lemon. The lemonade is what you can do now that you have complied with the new code. Hello to no-work-fertilization and hello to no-mosquitoes.

We would love to give you a no-obligation Promise. (A Promise is our guaranteed, up-front price. It's not an estimate.)

The Art of Hootness

I want to tell you about a Waco shopkeeper that is an inspiration to me and should be to all shopkeepers everywhere. Her name is Karyn and she owns a remarkable cooking shop called the Gourmet Gallery.

Now, I'm only slightly acquainted with my friend's office manager, but she and her husband have just had their first child. I asked Karyn to make up a gift basket for her. "What do you want?" A very logical question, I'll admit, but one I was completely unequipped to answer. As I said, we were only slightly acquainted. "I'll work something up."

I traveled to Gourmet Gallery to pick up the basket and deliver it to Hewitt Chiropractic, the lair for Drs. Michael and David Moore, and Rene, their now-on-maternity-leave office manager.

To me, it was a nice basket.

"Rene's been in here before," Karyn said. "I think she'll really like this. I called her office and found she's a hot chocolate connoisseur. And, I know she likes nice things."

Is this obvious to you? This Waco shopkeeper gave enough of a hoot to call my recipient's office. I think that's laudable, but, let's face it--that kind of effort could be a written requirement in some This-Is-The-Way-We-Do-It-Here manual. But she *remembered* her coming in and *remembered* the kind of stuff she likes. That's not in any manual. That's hootness.

Hootness is rare, but it's not totally absent in this town. We want and hope Rainstat's customers see hootness in us, too.

Okay, I realize blogs are largely soliloquies but, if no one but me reads this, I want to encourage myself to start looking for hootness and shouting it from the mountain tops when I find it.

And, I'd bet that basket knocks her socks off. Thanks Karyn.

What a hoot!

Is It Time to Update Your Technology?

Picture a chisel and a rock vs. a pencil.

Or, how about a more up-to-date comparison of a ledger book and a computer with accounting software. The old way still works but the new way is better (faster, cheaper . . . ).

That's the way the Rainstat controller is. Your old sprinkler controller still works, but it is obsolete. Throw it away. Quickly.

The new controller is the same forward step you took when you got a controller in the first place (instead of turning on manual valves).

Maybe I'm wrong. Let Rainstat Irrigation look at your sprinkler system. We will both know within 10 minutes if it is a good move for you.

Self-Serving Change In Tag Line

"The best way to repair or upgrade your sprinkler system without getting soaked." It's self-serving chest-thumping, I know. But in thinking about how we go about the relatively simple task of replacing a sprinkler head, we do it so you should NEVER have to address that head again!

Does it cost more? That depends on whether your looking at cost from the initial expense to get the job done or the cost over the life of your system. The answer is probably "yes" and "no." Yes, it probably will cost you more to have it done right as apposed to just unscrewing one head and screwing another in its place. No, when you consider that you should never ever have to address that head again.

It's the old "pay me now or pay me later" reply, but if that head has to be repaired again (because your riding lawn mower broke the riser again), you shot yourself in the foot by paying too little.

Here's the new tag line, "The best way to permanently repair or upgrade your sprinkler system without getting soaked."

Okay. I feel better now. What do you think?

The New Cost of a Sprinkler System-Count Your Zones

Perhaps you have just moved into a home that does not have a sprinkler system, or you're building a new home. Maybe you've read that the addition of a sprinkler system is smart, both from a resale standpoint and as a necessary convenience. So you call around to get some prices from a few companies. (In case you didn't know, Rainstat rarely installs a sprinkler system. We just repair and upgrade them.) Do you go with the lowest? How about the highest? How do you know?

The cost of a sprinkler system is normally thought of as the initial cost--the cost to get it installed. But, how much does it cost to operate? We believe you need to consider operating costs because it is inevitable that costs are going to go up. Maybe a lot.

What factors do you consider when you are trying to determine how much it costs to operate your new or existing system? The process of calculating your system's precipitation rate, a water audit, (some cities that are running out of water are requiring it. Not here, thankfully.) is more complicated than we want to go into here. It can be calculated if you know each head's flow and distance or by literally placing tuna cans all over your yard and measuring the water in the cans over a set amount of time. Call this the Left Brain approach.

Your sprinkler controller, aka "clock" or "the box on the wall," turns your sprinkler system on and turns it off. That's it. Simple. But the decision of how long it stays on for each zone is the critical factor in your operating costs. How is your system broken up into separate, distinct zones? Do you water the shady part of your yard on the same zone you water the sunny part? The shady part needs less water. Is there any way for you to let that part run less than the sunny part? If not, you have a decision to make, "Do I water log the shady part or starve the sunny part?"

These areas are called "hydrozones." And the more accurately you group similar plant materials, shade and slopes, the more efficient you can be--which normally means more is better. But here's the rub.

Your irrigation contractor wants you to have the absolute best system money can buy, but he knows you don't know how to judge that. He also wants you to choose him and knows that his competitor is also bidding this system. So he compromises. He designs your system by covering the area with as few zones as your water supply will allow. Lower price now, higher price every month after that, forever.

What's the difference in price? Easily double--or more! Will you recoup that? Yes, but it can take some time--or maybe not. That's your call.

The bottom line is this: Every new sprinkler system MUST have a scale drawing that shows each head and each zone's area. Under the new rules that went into effect in 2009 it MUST also show every major tree (shade) and hardscape (sun exposure). Look at the plans. Did the irrigator divide your zones by hydrozones? If s/he did, it is probably more expensive initially and cheaper to run.

Now you can get that calculator out and engage your left brain again. Happy calculating!

P.S. If you want to really save water, let us install our smart controller and weather station. It programs itself every day so no water is wasted. Ever.

Autopilot vs. Throttle Lock

I'm no pilot. I know a few and they love Autopilot--especially on long trips. These sophisticated devices keep the plane on a strait and level path at a constant speed. The pilot can sit back and literally read a book with the confidence that the Autopilot is taking care of the plane at least as well as s/he could.

Now consider a simple throttle lock. All it does is keep the engine's speed constant. Sit back and read a book with a throttle lock and it will likely be your last. It will keep your engine speed (not necessarily your plane's speed) constant as it flies you right into the ground. That's precisely the difference between your present sprinkler controller and a Rainstat Controller.

So, in the parlance of Generation Twenty-Something, your *ancient* controller is dead on with the throttle lock. You set it and it repeats your last instruction from now until you intervene. It changeth not. It can't. And it wastes a lot of water because it cannot react to weather conditions. In the process, it "flies" your wallet right into the ground.

Not so with your Rainstat Controller. Like the Autopilot, it reacts to every subtle weather change and corrects itself so your landscape gets just enough to thrive. This used to cost tens of thousands of dollars. You can get one installed for $995.

A Rainstat Controller and Weather Station is the best way to put your sprinkler system on Autopilot.(sm) Please call 829.3800 now to scedule a free on-site analysis of your sprinkler system.

September, The Foothills of Winter

September is when the weather breaks. Usually. It's a "transitional period" sprinkler-wise. And, it's one of the most water-wasting times for sprinkler system owners and managers because it is still summer and summer schedules seem to be sticky.

Here's the averages you need to start with: The average rainfall for Waco in September is 3". The need for water as expressed in the evapotranspiration (ET) rate is 5.7". So you need to replace 2.7 inches for the month. The reality of it though is the 2.7" needs to be weighted toward the first half of the month when, like today, Labor Day, it is supposed to be in the upper 90s.

So, if you don't yet have a Rainstat Controller (it makes your adjustments for exact water savings every day), please pay attention to your sprinkler's schedule and make the transitional adjustments.

Specifically, I'd stay with my August need of 5.7" until we start seeing some high temperatures in the mid 80s with cool nights. Then I'd drop the schedule to 25% of the August run-times.

Is all this Greek? Call me at 254.829.3800. It all has to do with conserving water (and saving you money) while keeping your landscape vibrant and healthy. The Rainstat Controller is a "Green" or "Smart" controller. It's like a thermostat for your yard.(sm)
