Snowpack: Here today, gone tomorrow?

A recent study finds that climate change means less water from melting snow. So what are we doing about it?

By Kim Unger

snowpack measure winter park

Denver Water employees stationed in Winter Park take measurements of snowpack in 2014.

Denver Water’s extensive reservoir system helps us monitor water supplies, even as a new climate change study warns of a shrinking snowpack.

A recent study from the Earth Institute at Columbia University found that the snowpack in the Northern Hemisphere has a 67 percent risk of declining — greatly reducing the amount of drinking water available from that source.

The study focused on river basins that rely on snowpack and are not adequately replenished by rainwater. The study identified the Colorado River basin among those at high risk for greatly reduced snowpack in the future, when demand for water will outpace availability. The river provides water to seven states, including Colorado.

As worrisome as that sounds, the study doesn’t provide a complete picture of how climate change may affect Denver’s water supplies, said Laurna Kaatz, Denver Water’s climate adaptation program manager.

She isn’t raising any alarm bells.

“This study is a big picture look at how sensitive systems are to different conditions,” Kaatz said. “It’s not a deep examination into the full range of possible climate changes Colorado could experience in the future.” Nor does it dive into how water managers in Colorado are contending with those potential changes.

“We have to consider all of the local variables in our planning,” she said.

Those variables include population growth, how efficiently customers use water, environmental and ecosystem needs, and local climate and weather patterns.

Denver Water’s supply is mostly from snowpack. The snowpack — the total amount of ice and snow on the ground — fluctuates from year to year. In warm, dry years, it can be gone by mid-summer; in wet years it can last through the next winter season.

“Our region experiences huge fluctuations — or variability — in weather and climate conditions,” Kaatz said. “Fluctuations, especially in precipitation, mean that the rivers and streams that supply our water are also highly variable. This is why reservoirs are so important in Colorado. Colorado’s high peaks protect the snow for months out of the year, and our strong reservoir system protects our water supply against seasonal and annual variability.”

Making sure water is available when customers need it requires careful management of how water flows in and out of reservoirs. Kaatz explained, that when the snowpack melts, we capture what we need and store it for future use. In years of drought, reservoir levels go down, and customers need to be even more conscious of water use.

Denver Water works with the scientific community to stay up-to-date on the latest models and trends because we live in such a variable climate.

“As the climate continues to warm, we do anticipate that snowpack will not live as long into the summer and fall months, especially in warm, dry summer and fall seasons, and that variability will increase,” Kaatz said. “At Denver Water, we plan for the long-term and look at the many different challenges we could be up against in the future, including climate change.”

While the study gives a potential glimpse into our water future, the full story is really told in how well Coloradans have embraced water conservation. Per capita water use among Denver Water customers hit a 50-year low in May, a savings of 2 billion gallons compared to recent years.

9 reasons we’re giving thanks this Thanksgiving

Water you thankful for?

By Jimmy Luthye

With Thanksgiving upon us, we didn’t feel right stuffing our faces without first sharing some of the things that made us most thankful this year.

 

1. Bountiful fills and spills.

Waterton_Canyon_Strontia

We had a lot of water this year, especially early. Three of our reservoirs set record highs in May, with a fourth recording its second highest total in history. Wetter is better.

 

2. Our water system looks like this.

Dillon Reservoir. ’Nuff said.

 

3. Turns out, it’s easy to do Thanksgiving without wasting water.

We’re thankful to have so many tips to enjoy the holiday while saving water. For instance, thaw your frozen turkey in the refrigerator — not under running water. Read and learn, as I have.

 

4. Nature.

We’re thankful we live in a place where we balance human needs and those of the animal world. And we’re thankful the public remained patient and safe during the recent extended closure of Waterton Canyon due to increased bear activity.

 

5. Mmm … Brisk, mineral and grassy.

In a bizarrely worded taste test in Rodale’s Organic Life magazine, we’re certainly thankful our water was named among the top 10 tastiest in the nation. To top it off, Michael Strahan and Busy Philipps tasted our water on Live with Kelly and Michael! Not too shabby.

 

6. We have some insanely dedicated employees.

He’s not just showing off for the cameras, folks. Our employees are constantly out busting their tails to make sure the water keeps flowing, and everyone can be thankful for that. It was never more evident than at about 3 a.m. on Oct. 22, when three water main breaks happened almost simultaneously around the Denver area. And we’re especially grateful to the employees who will be working this Thanksgiving Day to keep the water flowing for all of our holiday celebrations.

 

7. The Great Divide … Have you seen it yet?

This film came at a critical juncture for water in the West. It’s one of the most important films of the year, and we’re thankful for Havey Productions for their tireless efforts in creating it. Seriously. See it. Here are some ways to do so. Also, check out our film review here and watch our employee reactions here.

 

8. These moose.

What’s better than a moose on your porch? A bunch of moose on your porch, of course! Thank you, moose. And a huge thank you to our mountain caretakers (and their families) — like Per Olsson at Jones Pass near Winter Park who took this photo — for their dedication to keeping the water flowing in the heart of the Colorado wilderness.

 

9. You, our customers.

A sure sign of winter: Closing up the Morning Glory spillway

Capping the summer maintenance season at Dillon Reservoir takes expert work crews, planning — and a really big plug.

How do you keep debris and cold temperatures from damaging a giant spillway that measures 15 feet in diameter and features a more than 200-foot drop?

Get a really big plug.

That’s what happened on Nov. 6, when Denver Water crews placed a 6-ton steel plug into the Morning Glory spillway at Dillon Reservoir. The annual activity marks the end of summer and signals the start of winter maintenance season, when Dillon Dam’s caretakers focus on maintenance of the structure’s interior facilities.

The plug serves a primary and secondary function — first, it prevents cold air from entering the spillway, which could damage the outlet works and take hours of manual labor to melt the ice that builds up. It also helps prevent chunks of ice and snow from falling into the spillway and crashing more than 200 feet below.

Timing of the operation varies from year to year, though the rule of thumb is to do it when the reservoir’s water level is at least four feet below the crest of the spillway.

“That way, we have time to get back in here and remove the plug should we get sudden, unexpected inflows,” said Rick Geise, caretaker at Dillon Reservoir.

The cap was placed using a mobile crane provided and crewed by Terry’s Crane and Rigging out of Salida, Colorado; the company has provided this service to Denver Water for more than 15 years. Denver Water employees Rick Geise, Donald McCreer and Nate Hurlbut assisted, overseen by dam and hydropower plant supervisor John Blackwell.

“One of the best things about Dillon’s operations is its complexity. My team and I are involved in so many different types of projects that our job is never boring,” said Blackwell. “With good planning and the ability to adapt, projects like this one are not necessarily difficult — especially when you have a crew who are experts in performing their tasks safely and efficiently like we do here.”

Come early spring, Blackwell, the crane and crew will be back again to pull the plug, signaling the start of the summer maintenance season, where the dam’s crews will focus on larger capital improvement projects to keep the facility in tip-top condition.

A trip underground, into The Twilight Zone

You’ve probably never heard of Denver Water’s vaults, much less seen one. Neither had I. Until now.

By Jimmy Luthye

 

Vault.

The word itself evokes a sense of hidden mystery and intrigue. Naturally, I was surprised to find out about hundreds of Denver Water “vaults” buried underground throughout our service area. When I asked around, it seemed many of my colleagues also knew very little about these creepy little structures.

There was only one way to find out, and since I’m the new guy, it was up to me to delve into the dark corners of this hair-raising topic.

This photo shows a recently upgraded Denver Water vault.

Here’s what I learned:

  • Vaults are underground structures designed to give Denver Water crews a quick access point to water pipelines that send fresh water to homes, businesses, parks, golf courses and other locations in Denver and the suburbs we serve. With this easy access, crews are able to control water pressure, relay information and make adjustments on the fly.
  • Denver Water has a stable, yet aging infrastructure, and many of these vaults need upgrades (these are already underway).

Mark Almond, project manager for Denver Water’s vault projects, is leading the charge to improve these pivotal access points, helping them last far into the future.

Throwing caution to the wind, Mark agreed to take us underground into a yet-to-be upgraded vault. And thanks to video, you get to come along for the ride. As Rod Serling liked to say, “You’re moving into a land of both shadow and substance, of things and ideas.”

You’ve just crossed over into … THE TWILIGHT ZONE (na na na na, na na na na).

Tapping into the truth about (non-bottled) water

PepsiCo got ripped for using tap water in Aquafina bottles, but not because it’s bad for you. Especially in Denver.

By Jimmy Luthye

At Denver Water, we make it our business to keep up with the latest water news, locally and around the world.

One item that crossed our desk was this so-called PepsiCo “scandal.” The soft-drink giant has been taking its share of abuse lately after executives at Aquafina — owned by PepsiCo — admitted taking tap water (gasp!) and sending it through their rigorous, state-of-the-art purification process.

Well, duh. Forty-five percent of all bottled water in the United States comes from the tap.

This story has been in and out of the news for over a decade. You may recall:

Frankly, the attacks are silly and a little offensive to us, as we are proud providers of tasty tap water to 1.3 million people.

So why no love for tap water, despite all the taste tests, exhaustive water quality analyses and countless studies proving tap water is perfectly clean and safe?

In the water utility world, many of us have taken a fairly hard stance in favor of tap water, at the expense of bottled water. At Denver Water, we even threw down the bottled vs. tap gauntlet this summer. To recap:

  • Tap water is every bit as safe as bottled water.
  • Bottled water costs almost 3,000 times as much as tap water.
  • Many bottled water companies, such as PepsiCo and Coca-Cola use tap water. (Coke somehow avoided the attacks on PepsiCo, even though the company does the same thing.)
  • Denver Water’s water is sampled 16,000 times and undergoes 66,000 tests per year to ensure it remains of the highest quality.
  • On average, Denver Water customers pay less than $3 for every 1,000 gallons of water.

And let’s not forget about those bottles. According to Brita, Americans drink about 48 billion (with a B!) bottles of water each year — enough to stretch around the planet 230 times. That’s quite a few plastic bottles, which are terrible for the environment.

OK, so we’re admittedly a little passionate about our local water. But, we also know that bottled water serves an invaluable purpose around the world and in times of crisis, especially when water is scarce or unsafe. We even provide bottled water to our own customers during emergencies that create extended water shortages.

But, when the water is clean, tap water is hardly something to avoid. In fact, particularly in Denver, it should be celebrated as one of the greatest achievements in the history of human civilization.

Not exaggerating.

Flying high with the Thunderbirds

A Denver Water employee’s stint with the U.S. Air Force’s elite squadron

For many aviation enthusiasts, watching the Thunderbirds soar through the sky is a bucket list item. So in honor of Veterans Day, we’re proud to highlight one of our own who had a front-row seat as a member of this elite aerial demonstration team.

Today, Jim Dye is the system manager of Operations & Maintenance support services, where he oversees Denver Water’s inventory and vehicle operations, as well as trade shops and environmental compliance. But Denver Water is Dye’s second profession; he spent the first 30 years of his career with the U.S. Air Force. During his service, he was responsible for keeping the Thunderbirds in the sky by performing maintenance on the jets.

He is proud to say that in 62 years of the team performing, the Thunderbirds have never canceled an air show because of maintenance issues.

Dye enlisted in the U.S. Air Force in 1985, and 10 years into his service he was selected to be a member of the Thunderbirds, the Air Force’s elite aerial demonstration team.

The Thunderbirds tour the U.S. and the world performing aerobatic formations and solo flying in specially marked aircraft. The team not only entertains spectators, but also helps the Air Force recruit the next generation of fliers.

As a member of the Thunderbirds, Dye traveled about 265 days a year around the world. Many performances blur together, but Dye remembers one as particularly rewarding.

“We did a tour in Europe after the fall of the Soviet Union,” said Dye. “We did Romania, Bulgaria and Slovenia. It was absolutely amazing to go into the former Soviet Union. We were the first U.S. military to be in there. (The people) absolutely went nuts.”

Among his other favorite stops with the Thunderbirds were performances at Cheyenne Frontier Days. Dye enjoyed his visits to Cheyenne and made many friends there. His last Air Force assignment, before retiring in 2014, was in Cheyenne as the operations superintendent overseeing 150 nuclear missiles in Wyoming, Colorado and Nebraska.

When not keeping the Thunderbirds running high in the sky, Dye served several tours in the Middle East in support of every operation since the first Gulf War in 1991. He said he would pack his bags in a second and deploy again if given the opportunity — he misses the camaraderie.

Recently, Dye was selected to the Thunderbirds’ alumni board of directors for a three-year term. In this role, he helps maintain the team’s traditions, keeps up communication with alumni and schedules biennial reunions. “I’m one of seven board members who run the alumni association,” he said. “There’s a balance of taking care of the alumni while taking care of the current team.”

While Denver Water’s equipment may not reach speeds of 700 miles per hour, Dye is still trying to break barriers. He manages 12 different departments at Denver Water, including the warehouse, trade shops, fleet operations and environmental compliance.

When he’s not on the clock, Dye enjoys hunting and fishing. “Alaska really spoiled me for fishing, though,” he laughed. Most of all, Dye enjoys spending time with his wife, Michelle, and their five children, ranging in age from 12 to 25.

He clearly wasn’t looking for a slow-paced retirement from the Air Force. “It’s just not in my DNA (to relax),” said Dye. “It’s been this way since I was 18. Go, go, go.”

Does your water bill seem high? You’re not alone.

 There’s a lot of chatter out there about ‘unusually high’ water bills. We found out why.

By Travis Thompson

Water bills seem to be the talk of the town.

Neighbors are complaining about higher-than-normal water bills in community forums like Nextdoor and Facebook. There have even been news stories on the topic, including one from 9News last week featuring one of our customers.

Many people along the Front Range are asking, “Why is my bill so high?”

It’s a fair question. And since we’re your water department, it’s on us to give you a fair answer. Here’s what we learned:

Stacy - through Sep 2015

Real customer’s water use through September.

Water bills were significantly higher this September compared to last September. Why?

Short answer: The weather.

Your water bill includes a chart detailing your water use, month-by-month, for the past year. Look at September 2014; it was an abnormally low water-use month. In fact, September 2014 saw the second-lowest total treated water volume since 1976 for that month. (September 2013, with its historic rain, ranked first.)

But 2015 was different. We had record rainfall in the spring, and customers used a lot less water than normal. In fact, single family residential water use was down 51 percent in June and 36 percent in July from our 2008-2013 baseline averages. See our story, “Water, water everywhere.”

In August, water use remained slightly below average. Then September and October arrived, and were much warmer than normal — September was even the warmest on record. Because of this, single family residential customer water use rose 6 percent and 23 percent from the average for those months.

And if you actually compare this September with September 2014, single family residential water use was 44 percent higher.

Higher water use, higher water bill.

But some customers apparently aren’t buying the weather explanation. On social media, some said they thought their water meters weren’t working. So we checked on that, too.

We read the meters all the time, and we’ll actually stop by your home and examine your meter if you think there’s an issue. Our testing and routine maintenance on our meters shows that less than 1 percent of them fail.

Even if there are issues with the automatic reader on your meter, like a dead battery or faulty wiring, the meter will continue to read consumption, and we can use that to get the correct reading.

In September, 160 customers reported higher-than-normal water bills. Here’s what our investigation turned up:

  • We found a water leak in 65 of these homes. Leaks will drive up your bill. Of those, we found 29 toilet leaks and 26 leaks in the irrigation system.
  • Another 31 customers were simply running their sprinkler systems too long. We urged them to use this tool to create a zone-by-zone schedule and dial-in their irrigation requirements.
  • Many of the homes had old, inefficient fixtures, and we helped customers make simple, water-saving upgrades. You’d be surprised what you save by replacing toilet flappers, showerheads and faucet aerators, not to mention Denver Water’s rebate program for upgrading to qualifying WaterSense-labeled toilets.

In many cases, we discovered multiple factors for higher bills, but all of them were easy fixes to get the customer back on the right track. If you think your bill is too high, you can conduct your own self-audit.

Stacy - through Oct 2015

Same customer’s water use through October.

 OK, so when will it get better?

Water bills will soon return to normal, but we’re not out of the woods quite yet.

This month, you’ll be receiving your water bills reflecting October use. Because October was warm, many customers didn’t winterize their irrigation systems when they typically would, thus extending the watering season. So for many customers, those October bills will also reflect a higher water use than the year before.

Fortunately, the snow is here and watering season is over, which will create a more stable bill reflecting only indoor water use.

One last thought

While some of the conversations we saw on social media weren’t exactly positive about Denver Water, we’re actually happy to see that customers are looking at their bills and paying close attention to their water use.

After all, understanding your own water use is a great way to help you realize how efficiently you are using our most precious resource — or what you can do better.
