Smart Irrigation Month Finale

Smart Irrigation Month has zipped right by, much like the rest of the summer! We have had the weirdest weather here in Siouxland this summer. Heavy rains coupled with days of fast-drying heat. This was a great summer to show folks the usefulness of a rain shut off device! I have had calls from customers thanking me for explaining the benefits of these devices and installing one on their system. Not one customer has regretted having one installed.

 

Following is our last installment from the Irrigation Association for Smart Irrigation Month - (The words in italics are from me)


Water Wisely

Today’s irrigation systems include sophisticated controllers that allow you to easily adjust watering schedules to fit different needs.
  • Get in the zone. Schedule each individual zone in your irrigation system to account for type of sprinkler, sun or shade exposure, and soil in that section. Different zones will almost always need different watering schedules.  (This is where Smart controllers really shine with zone by zone precision controls)
  • Consider soil type. Type of soil determines how quickly water can be absorbed without runoff. Watering more than soil can absorb causes runoff and waste.  (The clay soils of Sergeant Bluff are going to hold water much longer than the sand soils of Dakota Dunes)
  • Don’t send water down the drain. Set sprinklers to water plants, not your driveway, sidewalk, patio or buildings.  (I don't care how much you water it, concrete isn't going to grow! Keep it on the grass!)
  • Water only when needed. Saturate root zones and let the soil dry. Watering too much and too frequently results in shallow roots, weed growth, disease and fungus.
  • Water at the best time. Watering during the heat of the day may cause losses of up to 30 percent due to evaporation. Prevent water loss by watering when the sun is low or down, winds are calm and temperatures are cool — typically between the evening and early morning.
  • Water more often for shorter periods. For example, setting your system to run for three, 5-minute intervals lets soil absorb more water than watering for 15 minutes at one time, reducing runoff.
  • Adapt watering to the season. Familiarize yourself with the settings on your irrigation controller and adjust the watering schedule regularly based on seasonal weather conditions. Or invest in a smart controller so your system can make these changes automatically.


Smart Irrigation Month is over, but that doesn't mean you should stop being a smart consumer. Take care of your sprinkler and your mower. Your yard will thank you by staying green, lush and healthy AND need less water!

Have a super week!

Keep it Green!

Smart Irrigation Month

 The weather here in the Midwest has been like a wild roller-coaster ride the last few weeks. We seem to have gotten out of the severe thunderstorm pattern and arrived at HOT and dry. We have certainly had some weather that made having a smart controller or a rain shut-off device a very wise investment.


July is just a couple days away and it is typically a high water use month. The Irrigation Association has deemed July "Smart Irrigation Month". We all want you to have a green grass and all the wonderful benefits that come along with having healthy turf-grass, but we want you to be smart water consumers.
This from the Irrigation Association:
Automatic sprinklers offer convenience and control in protecting your landscape investment. Irrigation systems help you to enjoy your yard, and to keep it healthy and beautiful. However, most homeowners tend to over water their lawn or waste water through inefficient habits. Adopting water-savvy habits is essential to maintaining and extending your community's water supply, especially during peak use.
The key to efficient outdoor irrigation is applying just enough water and only when necessary. Water-wise habits will result in a healthier lawn and landscape, in addition to conserving water. Plus, reducing your consumption will help reduce your water bill.
 How can you be a smart water consumer? Here are a few pointers.

Inspect your sprinkler on a regular basis. Check for leaks, broken or clogged heads, and other problems, Clean drip-irrigation filters as needed. Don't assume that a sprinkler serviced in April will not need any repairs for the entire season - mowers, cars and kids can quickly misalign and damage heads. Be aware of any wet areas or run-off in and around your property.

Adjust sprinkler heads. Correct obstructions that prevent sprinklers from distributing water evenly. Plants and grasses grow very quickly and can block or clog heads. Keep water off pavement and structures (they don't grow!)

Consider a Smart controller or install a rain-sensor. If you missed learning about Smart Controllers back in April, here is a link to the blog entry (http://jensensprinkler.blogspot.com/2010/04/smart-controllers.html) and we talked about rain sensors in March (http://jensensprinkler.blogspot.com/2010/03/rain-sensors-or-rain-shut-off-devices.html). Each of these devices will pay for themselves in water savings.

Water at the optimum time. Water when the sun is low or down, winds are calm and temperatures are cool - between the evening and early morning - to reduce evaporation. You can lose as much as 30% of water to evaporation by watering mid-day. We recommend completing your water cycle before the sun rises.

Don't over water. Watering too much and too frequently results in shallow roots, weed growth, disease and fungus. Water just enough to keep your grass green. The appearance of your lawn will tell you it is time to water if you are not watering enough. The leaves will begin to wilt/curl and develop a bluish cast. It will recover quickly once water is applied. Try not to wait until your grass is browning out to apply water. The point here is to find a happy medium.


Hopefully this will give you a starting point for being a smart water consumer.  If you are unsure if your sprinkler is running at peak efficiency, have it checked by a professional.

Have a super week!
Keep it green!

Rain Sensors or Rain Shut-Off Devices

The weather this week looks delightful for early spring. Sunny days and above average temperatures. You can almost hear the sigh of relief from the entire Midwest.

In the forecast for the weekend is the possibility of thunderstorms. Now that the threat of flooding as receded we could use a good rain to just wash away all the dirt and muck left behind from the snow melt.

Rain is almost always a good thing, it does complicate our job as it creates delays, but God is always more effective at a good watering than anything man can try to design. What is not a good thing is running your irrigation system while it is raining or when adequate rainfall has occurred. Water is our most precious natural resource, we need to be certain we are not being wasteful. Water use regulations are increasing in every state. We have not seen many restrictions in our area, but I can guarantee it will reach here within the next few years.

As a home owner, what can you do? Can you have a sprinkler and be a responsible steward of the water we have available? Yes, you can. The easiest and least expensive change you can make to your sprinkler system is the installation of a rain shut-off device.

Your sprinkler controller is set to run on specific days and times. It does not know if it is sunny or rainy or if we had thunderstorms yesterday that dumped 3" of rain in the area, it just knows that is it suppose to run. A rain sensor determines whether or not enough rainfall has occurred in order to skip an irrigation cycle. How? The electrical connection between the sensor and your sprinkler system controller is interrupted when a certain amount of rain triggers the device. The sensor breaks the electrical connection so that electricity cannot flow to either the sprinkler valves.

At Jensen Sprinkler we install a wireless rain sensor that utilizes a cork disk, or expansion device, to determine when to shut off the system. This device uses a pressure switch to break the electrical connection. These can be adjusted in increments of ¼" to the desired rain fall setting. This adjustment is usually set to turn off the sprinklers after ¼" of rain has fallen. When the water evaporates and the disk shrinks, the pressure is released from the switch, the electrical connection is restored and the controller will run on the next scheduled cycle.

The best part about a rain shut-off, besides saving water, is that you don't have to remember to turn the sprinkler on or off with the changing weather patterns, the device does the regulating.

If you do not have a rain sensor, we recommend you have one installed, it will pay for itself in water savings within two seasons. Besides, conserving water is the right thing to do!

Have a super week! Enjoy the sunshine!
