“Smart” VS “Not-so-smart”

Rain Bird ESP-SMT4 Smart Controller

The “not-so-smart” or “traditional” irrigation controllers required us to determine how much to water and when. With the “smart” irrigation controllers you simply program in the conditions for each zone. The programming information includes:

• light conditions (full sun, 25% shade, 50% shade, 75% shade, and full shade)
• plant type (grass, annuals, groundcover, shrubs, and trees)
• amount of slope (0°-2°, 3°-4°, 5°-7°, 8°-Up)
• soil type (sand, loamy sand, sandy loam, loam, clay loam, silty clay, and clay)

Another feature is the on-site weather sensor that communicates current weather data on a regular basis back to the controller. The weather station measures rain fall and temperature and compares this information with the programmed historical data based upon the zip code entered. As weather conditions change, the irrigation schedule adjusts accordingly on a daily basis.

Programming

When the controller is programmed correctly, you can expect to maintain a healthy landscape while consuming up to 50% less water than “traditional” time-based controllers. One bonus feature of some “smart” controllers is that you can program the controller anywhere you want. The old days of standing out in summer heat and trying to program your controller while having difficulty reading the display are over. All you have to do is install a 9-Volt alkaline battery in the controller and program it from your couch inside your air conditioned home. The pre-programmed information is saved in non-volatile memory for retrieval at a future date.

Rebate programs

Summer is coming soon and why not start the season with a “smart” controller to do all the work for you. Save water and save money! Check with your water provider, as some offer controller rebates and may be able to assist with the cost of the unit such as the cities of Scottsdale, Peoria, and Chandler. Also in the spring, Salt River Project (SRP) has a Water Conservation Expo and offers a “smart” irrigation controller discount. For more information on “smart” irrigation controllers, visit SRP’s Facts and Questions page. Remember there are a number of ways to save water, and they all start with you.

Heat tolerant trees like the Palo Verde often have small leaves, light green or grey leaves, are native to arid climates, and can tolerate intermittent watering

Do you have questions about planting a tree or caring for existing trees in your yard? Joanne Toms, Water Conservation Specialist, from the City of Glendale is here with some helpful Q&A. Just in time for Arbor Day, which is today (Friday, April 27th)!

What type of tree should I plant?
Pick a tree that can survive and thrive in our desert region. Heat tolerant trees often have the following characteristics: small leaves, light green or grey leaves, are native to arid climates, and can tolerate intermittent watering. For a copy of the popular Landscape Plants for the Arizona Desert, which features more than 30 desert-adapted trees, contact your local water conservation office.

Where should I water my tree?
Nature knows best. Imitate nature by watering your tree at the drip line (at the outer reaches of the canopy of the tree). This is also where a tree naturally sheds rainwater. The most active water absorption area is at the drip line and beyond, not adjacent to the trunk.

How much should I water my tree?
You need to fill up your tree’s underground water storage tank – the “root zone,” or the soil surrounding the tree’s roots. Be sure to water the tree’s root zone which is 24 to 36 inches deep. A good way to test how deep you have watered is to use a soil probe or a long screwdriver. Just be sure to know where your irrigation and utility lines are located, first. Several hours after watering, push the probe into the soil. It will slide easily through wet soil but will be difficult or impossible to push through dry soil. Check out this handy brochure on how to best water your trees.

Consider different watering depths for different types of plants.

New Tree Trail Dedication April 28
Just in time for Arbor Day, Glendale’s Conservation & Sustainable Living program has opened its new addition to the Glendale Xeriscape Garden, the Tree Trail. This project, funded by a grant from the U.S. Bureau of Reclamation, features a renovated 10,000-square foot area of the garden, with a focus on small- and medium-sized trees better suited for most residential landscapes where space may be tight. Residents are encouraged to come and enjoy the new Tree Trail and the surrounding Xeriscape Demonstration Garden. The new Tree Trail is located at the city’s Main Library, 5959 W. Brown St., and open sun up to sun down every day.

The Glendale Tree Trail showcases small to medium sized trees that would be suitable for residential properties. Check out the Grand Opening Celebration this Saturday, April 28 at 9 am!

Swimming pools are great to help us beat the heat, but occasionally we may need to beat the leak! Pools can leak constantly or may only leak when the pool equipment is running. This can lead to water waste and a high water bill, and with pools being one of the greatest water users outdoors, it’s important to make sure they are being operated as efficiently as possible.

Leaks in your pool system may be difficult to find, even if you have used your meter to check for leaks*, for one of two reasons. First, if you have an autofill device, it will continue to keep the pool’s water level the same by adding water on a more frequent intermittent basis. Second, if you fill the pool yourself with a hose, you may not notice that you are adding water on a more frequent basis.

First, Look for visible leaks:

Most leaks associated with the pool are found in the pool equipment. Periodically turn the pool equipment on and look for visible leaks. Look for white crusty mineral deposits on pipes which could indicate a slow leak. Also, look for wet spots on the ground around the pool, pool equipment, and between the equipment and the pool.

Next, Do a Bucket Test to see if there are Non-visible Leaks:

You can read the instructions below or watch: How to Video for the Bucket Test

1. The bucket test is simple. Let’s get started by collecting a couple of items. You’ll want a bucket and a wax pen. Stop manually adding water to the pool or turn off the water to the pool’s autofill until the test is complete.
2. “What is an autofill?” It is a device that fills your pool with water automatically. As with skimmer baskets, autofills are typically located next to the pool inside a recessed container beneath a round lid.
3. If you have an autofill, let’s turn off its water supply. Find the pool’s backflow device which is usually located at the back or the side of the house. The pool’s water supply line is usually the first line out of the pool’s backflow. Turn its shut-off valve to the off position.
4. Also, no splashing water out of the pool during the bucket test.
5. Place a bucket or container on a pool step without submerging it, and then fill it with water so it is the same level with the pool water. Use a wax marker to mark the level of the water in the pool and the level of the water in the bucket.
6. Wait a minimum of two to three days to let natural evaporation occur. If it rains or it’s a windy day you may have to redo the test. If the water level in the pool has dropped more than the level in the bucket, you have a leak. If both the levels go down but are the same in the pool and in the bucket, then you do not have a leak.
7. If you have a leak, you can do a little more testing to indicate whether leak is in the pool structure or the plumbing system.

• Repeat the test with the pool equipment running.
• Repeat the test with the pool equipment manually turned off so it can’t run.

If tests reveal that more water was lost with the pool equipment running, the pool’s plumbing is probably the cause.

* Not Sure How to Use Your Meter to Check for Leaks?

If you have a high water bill and you’re not sure if it’s the pool or something else on your property, start your search by using your water meter as a leak detection device. Watch our How to Read Your Meter video!

Note: If you live in Phoenix, your meter reads in cubic feet. One cubic foot equals 0.748 gallons. So, if you determined that 100 cubic feet were used during a meter test, then 74.8 gallons was used.  All you have to do is multiply the cubic feet by 0.748.

What is a traditional spray nozzle, you ask? In a nutshell, it’s any nozzle that delivers small water droplets quickly and in a fan shaped pattern. Due to the high flow of water coming out of traditional spray nozzles (almost 2 gallons per minute, 15’ half-circle), many aging sprinkler pipes get mineral buildup and can no longer provide the needed pressure to deliver water evenly between the originally designed head-to-head spacing. Most homeowners try to solve this issue by simply increasing run-times until the brown spots disappear. However, while this solution may improve the look of the site, it results in a tremendous increase in water consumption, with some areas getting a lot more water than needed, which is both costly and environmentally unfriendly.

Homeowners can take a cue from landscape professionals, who have learned to rely on multi-stream rotating sprinkler heads, such as the Hunter MP Rotator. The MP Rotator features a unique, multi-trajectory rotating stream delivery system that achieves water-conserving results. Rather than simply “spray” water onto landscapes, MP Rotators deliver multiple streams of water at a slow, steady rate. The reduction in flow will boost system pressure allowing the MP Rotator’s multi-stream “moving fingers” to achieve previously compromised head-to-head spacing.

This is what makes MP’s perfect for revitalizing older systems—the retrofit can solve both low pressure and poor coverage problems. The MP Rotator can be installed onto any conventional spray head body transforming them into high uniformity, low precipitation rate sprinklers. But be careful. Because the MP Rotator has a much lower flow rate (1/2 gallon per minute, 15’ half-circle) compared to a traditional spray nozzle, a complete removal of ALL traditional spray nozzles on a single valve (station) must be done. By mixing MP Rotators & traditional spray nozzles on a single valve (station), an already inefficient system will only become worse.

Another added benefit is the MP Rotator’s compatibility with Arizona soil absorption rates.  Most Arizona landscapes consist of clay soil profiles capable of absorbing only a ½” or less of water per hour. In Water – Use It Wisely’s 100+ Ways to Conserve, # 18 states If water runs off your lawn easily, split your watering time into shorter periods to allow for better absorption. That’s because most traditional spray nozzles deliver water at flows 100-200% faster than what Arizona soils can absorb.  Due to the MP Rotators “Slow-the-Flow” nature, it delivers water to your landscape at a much slower rate therefore minimizing or eliminating unnecessary run-off. This slower application rate allows water to gently soak into the soil, and achieves an even distribution throughout the area being irrigated. This increased efficiency results in 30% less water use when compared to traditional sprays, and significantly reduces wasteful runoff.

MP Rotators are also a great choice for new systems, as they provide immense range, flexibility and provide better system efficiency.
