Four generations keep water flowing through Denver
Since 1948, Denver Water has not gone a year without a member of Joe Maynes’ family.
The Maynes family roots run four generations deep at Denver Water, a legacy so broad that his great-grandsons are now fixing pipes he buried decades ago.
“I was working on an emergency repair a few days ago and said, ‘I bet Joe Maynes put this in years ago,’” laughed Josh Martinez, Maynes’s great-grandson and a utility tech in T&D who started at Denver Water in 2023. “He had a way of doing things.”
In 1948, 15 years before Denver Water finished building Dillon Reservoir, Joe Maynes came on board as a Denver Water employee. He started in the field, laying pipe for the fast-growing city. Over four decades, Joe worked hard at the utility, leaving his mark throughout Denver’s underground and eventually retiring in 1988 as an assistant superintendent.
“I’ll be reviewing as-builts now, and I’ll see his name handwritten as the foreman who built it,” said Billy Martinez, water distribution supervisor who started at Denver Water in 1996 and is part of the third generation of Maynes’ family members at Denver Water.
“You’ll just come across it, and I’ll say, ‘Look, my grandfather’s name is on this,’” Billy said.
Billy recalled that his grandfather Joe didn’t talk much about the day-to-day work, but he was proud of his career that allowed him to raise a family and meet lifelong friends.
“He used to tell my mom that we’re all going to be Denver Water employees,” Billy said. “He always wanted us to fall in his footsteps.”
In the 1960s, Joe’s son Roy joined the utility’s electrical shop, the start of a career that spanned more than three decades at Denver Water.
Joe’s son-in-law, Gill Martinez (Billy’s father), was hired in 1974, starting as a caretaker at Gross Reservoir in Boulder County, later transferring to Dillon Reservoir and then to the metro area to be Denver Water’s district supervisor for the High Line Canal.
Billy was born when his father worked at Gross Reservoir and then moved to Dillon as a child when his father transferred to the Summit County reservoir.
“I remember Dad taking us to Dillon’s spillway, showing us the machinery down there and plowing snow,” said Billy. “I was awfully young.”
Bobby Padilla, Billy’s cousin and Joe’s grandson, remembers long summer days at Dillon with his cousins and winter vacations spent sledding down the mountainside with old rubber backhoe tires.
“We’d help Uncle Gill (Billy’s father) with cutting grass, chopping wood — we have lots of memories out there at Dillon,” Bobby said. He also remembers his grandfather Joe’s retirement party in 1988 and the scores of co-workers and friends who attended.
As later generations grew up and started raising their own families, they realized that Grandpa Joe was right. Denver Water is a great place to work.
“It’s a great company. If it wasn’t a great company,” Bobby said, pointing to his nephews — the fourth generation to come to Denver Water, “the younger generation wouldn’t be here.”
Like their fathers before them, Denver Water is a big part of the childhood memories of Maynes’ great-grandsons.
“I remember my dad getting ready in the morning, putting his boots on, and I wanted to follow in his footsteps,” said Josiah, Billy’s son and a T&D utility senior tech who hired on in 2019.
Josiah’s brother, Josh, who started at Denver Water in 2023, agreed, remembering his dad scooting out of baseball games early to respond to an emergency water line repair.
“Without water, people couldn’t survive,” he said. “People take it for granted, but it’s so important, and we see that every day.”
Billy said their family is close, often getting together on weekends, where they end up talking about what went on at work during the week. His grandpa Joe, who died 15 years ago, would be proud of his family’s continued legacy at Denver Water, Billy said.
“When people ask me how long I’ve been here at Denver Water, I say 49 years,” Billy said. “My whole life.”
