In the past 20 years, 14 of those years have been drier than normal, and six years wetter than normal.
Temperature
In 2019 New Mexico was warmer and drier than normal! 1.6 degrees above normal. This ranked in the 20th warmest on record for New Mexico.
The
average temperature for Albuquerque was
57.5°, which was 0.4° above the 30 years (1981-2010) normal of 57.1°.
The average contiguous U.S. temperature was 52.7°F, 0.7°F above normal. This ranked in the warmest third of the 125-year period of record.
Precipitation
Average precipitation for New Mexico was 0.52 inches below normal for the year but the 2.2” of rainfall in November made it the 2nd wettest November ever recorded.
In Albuquerque, the range of rainfall by zip
code is between 8-12 inches. The total precipitation for the Albuquerque area in all zip codes was
10.8” in 2019. A good year for Albuquerque and it shows in conservation efforts!
Above-average annual precipitation was observed across much of the nation. Many northern states had their wettest year on record, with much of the central U.S., northeast and parts of the west experiencing above- to much-above-average precipitation.
Conservation Highlights
How did Water Authority customers do this year to conserve our most precious resource? Excellent!
In 2019, customers used approximately 700 million fewer gallons than last year. 2019 per capita usage is 121 GPCD (Gallons Per Capita Per Day), that’s 4 GPCD less than last year (125 GPCD in 2018). Thank you for your continued action in helping us make progress toward reaching our conservation goal of 110 GPCD by 2037.
Customer Incentives (Rebates)
In
2019, the Water Authority returned $700,000 to customers through the rebate
programs. Just over half of that went to customers who replaced 450,000 square
feet of high-water use turf with a desert friendly xeriscape. To find out more
about rebates, visit https://www.505outside.com/rebates/residential/.
Adding Trees
Trees are a priority for
the Water Authority conservation program because of their many environmental
benefits and the unique role they play in landscapes. In 2019, customers planted
approximately 1,000 trees with the “Tree-Bate” program, which also helps
customers pay for tree care. Albuquerque customers have planted more than 3,500
trees in just three years! Additionally, the Water Authority Conservation
Program provided $60,000 for tree planting in city and county parks and open
spaces. That’s enough to plant an additional 225 trees per year.
Water Use Compliance
Water waste continues to improve from previous years! In 2019 the conservation department issued 732 Water Waste Warnings that resulted in only 77 violations. Thank you for servicing your irrigation system!
To avoid damage to your irrigation system from
freezing temperatures, it is important to “winterize” it by protecting exposed outdoor
fixtures. If your hose bib is left exposed or standing water is left in pipes, valves
or sprinkler heads during freezing temperatures, that water may expand and damage your
system fixtures. That
could result in costly but avoidable repairs. Each irrigation system may be different,
but the general idea is the same: protect your irrigation system now to save
time and expense later. Here are a few tips you should take to prepare your irrigation
system for winter.
1. Disconnect the water supply to your irrigation system
a. If you manually water using a hose or if the irrigation system is attached to an outdoor spigot, you should disconnect it and cover your hose bib using a faucet cover. A faucet cover is easy to install and is usually made from durable hard plastic. It protects your outdoor faucet from freezing temperatures. This in an easy, inexpensive fix that will provide you peace of mind when the temperatures drop.
Pro Tip #1
Faucet cover to protect hose bib from frost.
Disconnecting your hose and covering your hose bib is very important in winter. If you leave the hose connected, water can freeze in the hose all the way into the hose bib and the pipe that goes inside your home. If the house pipe breaks, you will have water flooding inside, and potential major water damage inside your home. It’s definitely worth the $10-$15 on these insulated covers to prevent potentially thousands of dollars in plumbing repairs and water damage to your home. Don’t assume that if the hose bib freezes it will drip and freeze only outside your home. Sometimes the damage is a whole lot worse.
b. If you have a below ground irrigation system, locate your shut-off valve (often hidden in a 3” PVC pipe; often with a white or yellow cap, as shown in the photo). Turn it to the right to shut it off. Be careful when turning so you don’t break the valve. Your shut off valve may look like this:

Tip #2
Sometimes the water shutoff for your sprinkler
system is in the green box shown in the picture. If so, we recommend adding some
heat tape and/or insulation in the box because it will be exposed to freezing temperatures.
If you can insulate it and protect it you can avoid potential frozen pipes at the
shut off and potential repairs in spring. Watch out for spiders, though,
because the shutoff box is a warm wet place.
2. Turn off the irrigation system controller (if you have one)

Pro Tip #3
If you forget to shut off your irrigation system during winter you can potentially have your automated sprinklers running in freezing temperatures. That can freeze and damage your sprinkler heads. Make sure you turn off all automatic cycles for your system. If you have a drip system for trees and other plants that need to be watered periodically throughout winter run the system manually when you are home, and only in above freezing temperatures. Don’t just assume that setting it to run during the day will be okay, either. There are days in winter when the temperature doesn’t get above freezing. It’s best to just turn it on when you’re home and then watch it. If your sprinkler heads do crack or break and you don’t notice, you will likely flood your yard in spring when you turn your system back to automatic settings.
3. Drain the water from all pipes, valves, and sprinkler heads.

There
are several ways to drain your system.
Manual
drain valves and automatic drain valves can be blown out with compressed air. Local
irrigation specialists can help.
If you
have an irrigation system with drip hoses, we recommend you locate the end cap (drain
cap) of the drip hose and drain out the water.
Pro Tip #4
Sometimes irrigation systems don’t have drain
valves. If you don’t have these, simply make sure you’ve turned off your sprinkler
system prior to winter and freezing temps. Then you can have a professional inspect
the system in spring before you turn it back on. A professional will inspect your
system for leaks and make any repairs so you don’t flood your yard. So avoid the
headache and have an inspection. If you consistently have problems year after year,
drain valves can be installed to help clear the lines each winter.
Reminder: If you need to water in the winter season use your hose and remember to cover it when finished.
How to shut off your irrigation system for winter.
Your landscape needs a lot less water in September than it did in the summertime. About 35 percent less on average. The days may still be warm, but shorter days and cooler nights in the months of September, October and November means less evaporation, which means less irrigation is required. Adjust your irrigation controller following the Fall Season Watering Recommendations to save water and money this Fall.
Ramping down your landscape irrigation does not mean you
need to stop watering all together. If you have a lawn, cut back to two days
per week. Cut back to two to four days a month for trees. Fall is when trees,
shrubs and other perennial plants get busy growing their roots, and proper watering
supports this activity. After spending the summer putting energy into growing
leaves, flowers and fruit producing plants take advantage of the fall season by
anchoring their root system to the earth. It’s important to fortify root systems
during the Fall so they have a stronger trunk and stem during the winter
season.
Fall season is also a great time to put in new plants, for the
same reason – they spend their time growing their root system instead of leaves
and flowers. But new plants need more frequent watering to help them get established.
Keep in mind that new plants need at least a month to anchor in the ground before
the first freeze, so don’t plant too late in the season to avoid damage.
And remember it is not necessary to irrigate when it rains, or on days following a good rain event (or about a 1/2" of rain). Using nature as your source of water encourages a desert friendly landscape.
Want to know how much your landscape really needs? Call 505-289-3003 to schedule a free, efficient irrigation consultation with a Water Authority expert.
The Water Authority encourages efficient outdoor water use for beautiful landscapes. With some 40 percent of our drinking water going to landscaping, improving outdoor water use efficiency is now the main focus of the Water Authority’s conservation efforts. But irrigation efficiency doesn't mean you can't have a beautiful, desert friendly yard. Below is your three-step plan for a beautiful, desert friendly yard.
1. Service your irrigation system by checking for leaks and malfunctions.
Low-maintenance landscapes are great, but there’s no such thing as a “no-maintenance” irrigation system. A single broken sprinkler head flowing at 15 gallons per minute will waste 900 gallons in one hour of use. Service your system regularly, and check it often for leaks and malfunctions.
2. Set your turf irrigation timer to water by the numbers.
Adjust your irrigation timer according to the season. For turf, water by the numbers: One day per week in March, two days per week in April and May, three days per week in the summer, and ramp down in the Fall. For other landscapes, follow the Seasonal watering recommendations. Call today for a free irrigation consultation.
3. Select desert friendly plants that thrive in our dry climate.
There are literally hundreds of plant options to choose
from that will thrive in our desert climate. And there are rebates available for
replacing turf with a desert friendly landscape.
If you follow this three-step plan, you’re sure to have
landscape success.
Grass lawns in the greater Albuquerque area require supplemental irrigation in order to survive our high desert climate. Most residential landscapes are watered by pop up spray heads with conventional nozzles, as pictured below.
Pop up spray head
But did you know that water waste from these conventional spray nozzles can be reduced by simply swapping the nozzle out for high efficiency rotary nozzles? And for just a few dollars per head. Rotary nozzles improve irrigation efficiency by delivering water more slowly. That prevents runoff by giving soil time to absorb the water and allows the water to reach the root zone of the plant. These nozzles also deliver water in a larger droplet size, making the spray less susceptible to being carried off by the wind. This is all accomplished via their distinctive multiple rotating streams of water, pictured below.
High efficiency rotary nozzle
505Outside visited local irrigation supply stores to find out their most
frequently asked questions about these nozzles.
Can I replace my existing spray nozzles with these high efficiency rotary nozzles?
Yes. In most cases it’s as simple as unscrewing the existing nozzle and
dropping in the rotary nozzle and filter basket. These are available at any
local irrigation supply store. If you bring in your existing spray head, the
staff can recommend the best solution for you. Water Authority has rebates
available for the purchase of rotary nozzles, too. Visit the link here.
Sounds too good to be true. Are there any negatives?
They tend to clog with the hard water typically found in Albuquerque.
Make sure the brand you select comes with an inline filter basket, so you can
easily flush out and unclog your spray head.
What else should I know about high efficiency rotary nozzles?
They require longer run times. This is where most homeowners get confused. Wouldn’t
a longer run time mean I’m using more water? The answer is no, because rotary
nozzles deliver water at a slower rate than typical spray nozzles. Therein lies
the efficiency: water saturates deep into the root zone rather than running off
and evaporating. This can also help reduce the frequency of runs, thereby
saving water.
They work best at 30-40 psi. If the pressure running through your irrigation
system is too high, the rotary nozzle will spin out of control and break. The
average pounds per inch (psi) in Albuquerque ranges between 40 and 70 psi, so
you may need a pressure regulator on your system to avoid damage. Check with
your local supplier to figure out if you need to regulate the pressure on your
system, and how.
They are adjustable. Most rotary nozzle brands provide matched precipitation rates across radius, arcs, and pattern types, making it easy to install a system with even distribution. Nozzles can be easily adjusted by tool or by hand while the heads are running, to avoid water waste through overspray.
Stop by your local irrigation supplier and learn all about these high efficiency rotary nozzles.

505Outside sat down with local landscape contractor Hunter Ten Broeck, owner of WaterWise Landscapes Incorporated, to chat about Water Harvesting in Albuquerque.
There are two categories of water harvesting techniques: passive water harvesting and active water harvesting. Passive water harvesting is the practice of slowing water down and encouraging it to soak into the ground. Water is collected from the source (roof, canale, downspout, or sloped earth) and directed to the landscape where the water can be immediately used by the plants. Active water harvesting uses rain barrels, cisterns, and other types of containers to store rainwater for later distribution. These typically hold as few as 200 gallons of water up to 10,000 gallons. A good calculation to remember is 1” of rain on a 1000 sq. ft. roof equals about 600 gallons of water.
Hunter
says the key to any type of water harvesting system, whether active or passive,
is to incorporate it into the landscape design. Thinking through how the rain
water will interact with your landscape and designing for that should be first
and foremost.
When asked what a homeowner could easily do to start water harvesting in their yard, Hunter recommended starting small and trying passive water harvesting. Passive systems can be as simple as a swale, a French drain (or rock burrito, as nicknamed by his staff), or more complicated systems that include building an underground soil sponge area. He says to start by finding the roof’s downspouts and canals, then provide a catch area underneath them. A catch area could be a concrete splash block or cobbles. Then direct that water away from the home via a cobble swale that runs into a planting area. This can be done easily by digging down a few inches and creating a slope away from the house into the planting area. Once the swale is dug, add cobble on top to stabilize the soil and prevent erosion.

To make Hunter’s “rock burrito” simply dig an 8” wide trench at least 12” deep and as long as necessary for the space. Slope the bottom of the trench toward the drainage area. Layer the trench with filter fabric followed by cobble or rocks. Roll the fabric over the rocks then backfill with soil. This will provide an underground collection area for water. Water will slowly soak into the ground providing moisture to adjacent planting areas.

For homeowners who are ready to tackle an active water harvesting system like a rain barrel or cistern, Hunter recommends adding a passive water harvesting system next to the active one for when the container overflows.

Using every drop of water through water harvesting is an important feature Hunter incorporates into all his landscape designs.
