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.
