How Long Should You Water In July and August?

Here's a rule of thumb: July and August call for 1.5 inches in addition to our normal rainfall (which is usually pretty-much nil) in the Waco area. But your sprinkler controller thinks in time not inches. So let's convert inches to time so you can better manage your sprinkler system and your water usage.

Rotors, the heads that shoot a stream of water and the head rotates, precipitate at about .5 inches per hour. That means it takes a whopping 3 hours a week to lay down 1.5 inches of precipitation! There always seems to be a trade-off between buying water and having a beautiful stand of grass. You will make you own decision on expenses, but 3 hours for rotors is the ticket to beautiful grass during our hot summers.

Sprays, the heads that shoot water in all directions at once, precipitate at 3 times as much as Rotors. They only need to run for an hour per week to get the same 1.5 inches of precipitation.

How often? The Waco area generally has very heavy clay soil. If you run your system for too long, it just creates runoff and wastes water. Try 3 times a week at 1 hour each for Rotors and 20 minutes for sprays. If you still have runoff, cut your time in half and double your days. For example set your controller for 30 minutes for rotors and 10 minutes for sprays and run it every day but, say, Sunday.

Your grass will thank you and your checking account will wonder what happened.

Remember to change it again when the weather breaks in September.

If you don't want to constantly tweak your sprinkler's controller but want green grass and as low a water bill as possible, consider our Rainstat Controller and Weather Station. It's not for everyone but you can check it out at our site. It's like a thermostat for your yard. You set it once and forget it.

Can we agree on what is Complicated?

Today's home sprinkler system tools would utterly fail if they modeled how your air conditioner worked in your home. You would have to look at the hour by hour weather forecast, and schedule your air conditioner to come on when the inside temperature got uncomfortable. But before you could do that, you would have to know 1. how long it takes for the outside temperature to raise the temperature in your house and, 2. you would have to know how long it took to lower the temperature once the a/c started.

Let's say you knew these two necessary bits of information and could calculate when your air conditioner should come on and how long it needed to run. Fine, but now you need to have some way of turning it off at the right time and turning it back on when it gets too hot.

Thankfully, you have a thermostat. It senses the current, inside temperature regardless of how hot it is outside, compares that current temperature to the desired temperature (set by you, once) and either turns the a/c on or off.

Yet a few people have told me that setting their sprinkler system by predicting when their yard needs water is simple and that setting the Rainstat controller (once forever) is complicated.

I believe that some of these objectors are really saying, "I'm afraid to give up control of my watering schedule because I'm afraid I won't be able to afford the water bill." Keep in mind that the Rainstat Controller has proven itself in saving between 20% and 50% on your annual water bill. That is assuming that your landscape was green before and you want it to stay green.

Granted, if your grass is in a state of stress all summer because you will not water the inch and a half it needs each week during our Waco summers, you have reason for concern. But if your grass is green now, giving up control of when and how much it runs will be as hard as it is to set your thermostat on 72 degrees and enjoying the automatic cool.

That's why we say, "It's like having a thermostat for your yard." Please call us today at 829-3800 to get all your questions answered.

Links To Other Water Management Sites

This University of Florida site talks about the best use of a traditional controller and rain sensor to corral your sprinkler system and your water bill. The problem is a rain sensor is only an interrupter. It still depends on you programming your controller to react to changing weather.

This North Carolina site touts a program that attempts to inform you so you can do a better job of programming your controller.

"Through a cooperative effort between the NC State University Department of Crop Science and the State Climate Office of North Carolina, an internet-based decision-aide called the Turf Irrigation Management System (TIMS) has been developed and is now available to the citizens of North Carolina."

Again, it still counts on you being the reactor to weather changes.

Populare Mechanics has an excellent article that surveys the different methods of using weather stations to program your controller. The systems that are controlled by a computer have been around for a while and are still quite expensive. This article also discusses the remote weather station that hooks up to your controller via satellite with a subscription service. The last option is the one that makes the most sense to us--an on-site weather station that programs your controller every day. They talk about one that we could recommend if it weren't so expensive. The weather station alone consists of two modules--each costing $450! You would still have to buy the controller, install it and program it's initial settings.

The more I read, the more excited I get about the Rainstat Controller and Weather Station. If you have questions, please call us at 254.829.3800.

Water Restrictions to the South

I just received a postcard from the Austin Water Utility recapping their rules for commercial and residential sprinkler usage. Beginning May 1 and ending September 30, you cannot water from 10 a.m. to 7 p.m. and commercial properties cannot water *at all* Saturday through Monday.

And how many lakes does Austin have? Lake Travis, Town Lake, the Colorado River . . . I don't think Waco has had water restrictions, but it does look like we would do well to exercise good water stewardship to avoid restrictions in the future.

If you go to Austin's Water Conservation web site, you'll see that the City of Austin will buy it residents a new, water conserving toilet. These are 1.28 gallons per flush. You can see the savings if you're comparing it to the old 5 gallon per flush toilets that we all had just 10-15 years ago. Realize that only about 7% of your total water usage is attributed to the bathroom. It's a good deal for Austin and for its constituents but it only speaks to that 7% usage.

Your landscape uses 70% of your total water on average. Do you see what impact the Rainstat Controller and Weather Station will have on this resource if it can cut it by 20% to 50%?

Who are we?

Hello. I'm Doug Saylor, the owner of Rainstat. We started this business back in 1991 in the Brownwood area and called it Just Lawns Irrigation. Actually it was called Just Lawns, period, because all we did was mow grass. It's been over a decade, though, since we have mowed any grass except our own so it was time for a name change.

Couple that with the most stupendous news since I've been repairing sprinkler systems and we thought it was time to have a name that more accurately described what we did. So Just Lawns Irrigation is now Rainstat. We named our company after the name of the sprinkler controller and weather station that we install on existing sprinkler systems. It turns a typical water-wasting sprinkler system into a water-conserving and money-saving phenomenon--all for under a thousand dollars. Think of it as like at thermostat, but for your yard.

A thermostat for your sprinkler system

The more you know about sprinkler systems the more stupendous this news is. If you don't know anything about a sprinkler system and are familiar with a central heating and a/c system and its controller or thermostat, you wonder why the Rainstat hasn't been here all along.

Let me start at the end: We now have a sprinkler controller that is as all-encompassing as your thermostat is--but for your yard. Your thermostat just has to know what the temperature is and what you want it to be. You don't have to turn it on, then turn it off, only to have to turn it back on--all day and all night long. We take it for granted. But your sprinkler system needs to know a lot more.

For your landscape to do well while using the least amount of water, your controller would need to know the amount of rain you have received, the kind of soil you have, the type of heads your system has, the humidity, the slope of the ground and your latitude and longitude. Whew! That's a lot to know and your controller needs to know that information for each zone in your system.

The Rainstat knows all of that. Because it connects to your on-site weather station, it recalculates your watering schedule, based on all that data, every 8 seconds! Before the Rainstat, you had to tell your sprinkler system to turn on the water every Monday, Wednesday and Friday for 20 minutes a zone and start it at 4 in the morning. Sound familiar? That is gone now.

This controller has shown to save between 20% and 50% on your water bill. And the unit can be installed and programmed for under $1,000! Do the math. How long will it take before the Rainstat has paid for itself?
