The hippo had to go, but the Denver Zoo slashed its water budget
Rocky Mountain sandhill cranes battle warmer conditions due to drought
Wildlife biologist Jenny Nehring and farmer Rob Jones talk about Sandhill cranes and their impact on the San Luis Valley.
DENVER — Zoos are of necessity big gulpers of water, a fact that has some zookeepers in the drying American West working to rapidly upgrade efficiency and reduce unnecessary irrigation or leaks.
Denver Zoo, formally known as the Denver Zoo Conservation Alliance, has rapidly reduced its demands on threatened and declining water sources, including the Colorado River.
Among the upgrades is a sea lion water filtration system that allows most of the water to be cleaned and reused each time the pool is drained. That’s saving more than 8 million gallons a year, zoo sustainability director Blair Neelands said. “You can get in there, scrub it with a toothbrush and refill it with the same water,” she said.
Similar upgrades to an African penguin showcase reduced its water use by 95% by largely eliminating what’s sent down the drain. (Like a backyard swimming pool, though, these tanks sometimes still need to be drained and refreshed with new water to reduce mineral buildup.)
“The biggest thing for us is swapping from dump-and-fill pools to life-support systems,” Neeland said.
Another biggie is replacement of a 50-year-old water main with funding of about $3 million from the city. There’s no way of knowing how much that pipe had leaked over the years, but Neeland suspected it was more than a million gallons a year. The savings should become apparent as the zoo tracks its water use over the next few years.
Creating hippo-sized water savings
When The Arizona Republic visited in 2025, the zoo was on the cusp of eclipsing a goal to reduce its water use by half of what it had been in 2018. The zoo had used 80 million gallons in 2024, or about 219,000 a day, a 45% reduction in just a handful of years. Much of the savings had come in the form of smarter irrigation practices and use of drought-tolerant native plants where possible. The landscaping also pivoted to recycled “purple pipe” water from the city, which owns the zoo’s land, restricting potable water to areas where animals really need it.
“When people hear ‘recycled water,’ they get worried about cleanliness and hygiene,” zoo spokesman Jake Kubié said. “But it’s safe for the animals, and it’s not their drinking water.”
Getting past the water conservation goal would mean draining the pool where Mahali the hippo spent most hours lurking with just his eyes, ears and snout visible to visitors. Because he spent so much time in the pool, the water needed daily changes. It amounted to 21 million gallons a year, not to mention water heater bills that drove the cost to $200,000 a year, according to zoo officials. They estimated that Mahali used as much water as 350,000 four-person households.
“This facility is outdated,” Kubié said. “Some day this will become a huge saver of water.”
That day came before year’s end, and it indeed brought a tremendous savings. The zoo shipped Mahali to a new home (and a potential mate) at a wildlife preserve in Texas and drained the pool one last time. Ending the daily change-outs shaved more than a quarter of the zoo’s entire water usage from the previous year. It put the zoo significantly beyond its goal.
Denver Zoo’s water savings are part of a broader waste- and pollution-prevention effort aimed at being a good neighbor in uncertain times, Neeland said.
“Water savings and drought is top of mind for anyone who lives in the Western United States,” she said.
In Phoenix, a different mix of animals
That’s true of the Phoenix Zoo, as well, where zookeepers must maintain landscaping and animal exhibits in a city that baked under 100-degree-plus high temperatures for a third of the days last year. The zoo creates a “respite in the desert,” spokeswoman Linda Hardwick said, but has no hippos, penguins, grizzly bears or many of the other species that would require big water investments for outdoor swimming or cooling.
“We really specialize in animals that will thrive in the temperatures here,” Hardwick said.
The Phoenix Zoo uses most of its water on landscaping. After a consultant’s 2023 irrigation assessment, the staff centralized irrigation scheduling under a single trained technician and employed technologies including weather-based controllers and smart meters. Salt River Project awarded $70,000 in grant funds for the upgrades and several thousand more for training.
The zoo uses about 189,000 gallons a day, she said. That represents a 17% reduction from 2023, or 20% when adjusted for the year’s particular weather and evapotranspiration demand.

Fire destroys home under construction in northwest Denver
DENVER (KDVR) — An early morning fire on Friday left a home completely ablaze in the Highlands neighborhood, just a week after another house under construction went up in flames in the same area.
The Denver Fire Department shared photos of the incident, as crews were called to 3643 Mariposa, where images show a fully consumed home under construction.
“I think they [firefighters] kicked in the neighbor’s door just to make sure nobody was at home,” neighbors Lucy and Kyle said. “Some of the other houses, their windows got blown out from the heat!”
Just 11 days earlier, on June 8, a home under construction caught fire in the same neighborhood near West 33rd and Navajo. Nobody was hurt in either fire.
And just about two years earlier, in July, another fire in the same area ignited around West 36th and Osage. All of the properties are/were under development by the same group.
“I wasn’t present for any of the fires,” Ryan Yoffe, a member of the developer group, said.
Yoffe does say he thinks he knows how the last two fires had been set, saying it’s the City of Denver that needs to do better with surveillance.
“It’s likely related to the amount of homelessness in the area, looking for properties under construction to live in or burn down,” Yoffe said. “The City and the Police Department need to do a better job patrolling to limit the number of homeless people camping in the neighborhood.”
Denver Fire Department officials say the most recent incidents are under investigation, but that nobody was hurt in either.

Rockies ride Kyle Freeland’s gem, Braxton Fulford’s double to 4-3 win over Pirates
The night belonged to Kyle Freeland, who joined the 1,000 K Club. The moment belonged to Braxton Fulford. The ninth inning — and a big sigh of relief — belonged to closer Antonio Senzatela.
Fulford hit a two-run, two-out, pinch-hit double in the eighth inning off Mason Montgomery to lead the Rockies to a 4-3 win over the Pirates at Coors Field in front of a Friday night crowd of 33,596.
Fulford drove in Tyler Freeman and Cole Carrigg, who scratched out back-to-back two-out singles off Montgomery.
“I had been warming up in the cage for that at-bat for a couple of innings, so I felt pretty prepared,” Fulford said. “I got an advantage count (3-1) and I knew he was going to come with the heater and I was all over it.”
Fulford caught Montgomery for three seasons at Texas Tech, so he knew the left-hander’s tendencies.
“It’s kind of unfortunate for pitchers that you catch, because you kind of get to see their stuff,” Fulford said. “You kind of understand more of who they are. So I do feel like I had the advantage there.”
In the ninth, the Pirates loaded the bases against Senzatela with no outs on a single by Marcell Ozuna and an error on a groundball by shortstop Ezequiel Tovar. But Senzatela struck out pinch-hitter Tyler Callihan and induced Jared Triolo to ground to Tovar, who started the game-ending double play.
“It was kind of a crazy ending to the game — bases loaded and no outs,” Freeland said. ” ‘Senza’ got a big punchout in that situation, picks up Tovar. Then Tovar gets another opportunity to turn a double play, and he gets it done.”
Before all of the late-game drama, Freeland pitched his best game of the season: 7 1/3 innings, two runs allowed on four hits, no walks, and eight strikeouts. It marked the fourth time in his career that he pitched 7 1/3 or more innings.
“Tonight, I thought he was absolutely exceptional,” manager Warren Schaeffer said. “I thought his body language was impressive. He attacked the strike zone — relentlessly. His heater had good ‘vert’ tonight. The breaker was good. It seemed like he was in control all night.”
“Gritty” is the word often used to describe Freeland. Dominant was a more apt description on Friday night. History-making works, too. Freeland’s eight Ks gave him 1,001 for his career, joining right-hander German Marquez (1,069) as the only two pitchers in franchise history to eclipse 1,000. Freeland struck out Marcell Ozuna in the seventh for No. 1,000, and then promptly fanned Brandon Lowe for 1,001.
The hard-core Rockies fans behind the dugout gave Freeland a standing ovation.
“I’m very grateful for the fans always supporting me, and for making it this long in my career to reach some of these milestones, especially with one ballclub,” said Freeland, who struck out eight and walked none for the second time in his career. “I definitely hear those fans when I pop out of the dugout after every inning.”
The 33-year-old Denver native blanked the Pirates for the first seven innings, giving up just two hits. Pittsburgh finally got to Freeland in the eighth, putting up back-to-back doubles by Esmerlyn Valdez and Triolo to cut Colorado’s lead to 2-1. Up to that point, it looked as if Freeland had the juice to throw a complete game, especially since he threw just 81 pitches.
Freeland was pulled in the eighth for right-hander Jaden Hill, who gave up an RBI single up the middle to pinch-hitter Bryan Reynolds, tying the game, 2-2. Then Hill hit leadoff hitter Spencer Horowitz, and Nick Gonzalez scorched a triple off the right-field wall, scoring Horowitz and giving the Pirates a 3-2 lead.
Colorado staked a 1-0 lead in the third against hard-throwing right-hander Bubba Chandler. Willi Castro’s single scored Ezequiel Tovar, who reached on a bunt single.
The Rockies extended their lead to 2-0 in the fourth on rookie first baseman TJ Rumfield’s leadoff homer. He sent Chandler’s first-pitch slider 427 feet into the right-field seats. It was Rumfield’s 11th homer and his 38th RBI.

Man arrested on suspicion of murder in Denver shooting near South Park Hill, Hale
Denver police arrested a 35-year-old man on suspicion of first-degree murder in a fatal shooting near East Colfax Avenue and North Dahlia Street.
Joseph York was arrested Thursday after detectives identified him as a suspect through interviews and surveillance video, the Denver Police Department said in a news release Friday.
Detectives believe York was arguing with the victim, 25-year-old Elijah Barr, before the shooting in the early hours of June 7, the Denver Police Department said in a news release Friday. The intersection is between the city’s South Park Hill and Hale neighborhoods.
Barr was found with multiple gunshot wounds and was pronounced dead at the hospital.
York is being held without bail in the Downtown Detention Center and is set to appear in Denver County Court on Saturday, jail records show.
