The North Park Water Tower and San Diego's First Tour Guide: Two Stories Most Locals Have Never Heard

By Hedda ParashosSeptember 19, 2026

The water tower looming over North Park has stood since 1909, but almost no one knows why it was built or what it took to keep it standing. And tucked into that same neighborhood's history is Reuben Williams, an African-American entrepreneur who became San Diego's first professional tour guide before the city had any idea what tourism could become.

A steel water tower built in 1924 still stands at the corner of Howard Avenue and Idaho Street in North Park, and almost every person who drives past it assumes someone has always known what to do with it. The truth is stranger and more interesting than that.

These two stories, the North Park water tower San Diego history enthusiasts keep circling back to and the nearly forgotten man who first showed visitors what this city had to offer, are the kind of details that turn a neighborhood into something you actually feel connected to.

Why the Tower Was Built, and Why It Almost Came Down

In the early 1900s, North Park was a streetcar suburb, one of several neighborhoods the city developed to pull residents away from downtown. Water pressure was a constant problem. Buildings on higher ground, and North Park sits on a mesa, couldn't get reliable water flow from the city's system without help. The tower, completed in 1924 as part of what's now known as the University Heights Water Storage and Pumping Station, was a solution: fill it when demand dropped, then let gravity do the work during the day.

The tower held roughly 1.2 million gallons, big enough that it was once described as one of the largest elevated tanks in the world. It stayed in active service for decades, longer than most people realize, before being decommissioned in the 1990s as the city's pumping infrastructure made elevated storage unnecessary.

What preserved it wasn't a last-minute rescue from the wrecking ball. It was a paper trail. The North Park Historical Society prepared a formal nomination in 2012, the State Office of Historic Preservation approved it as a significant California resource in 2013, and it was added to the National Register of Historic Places that June. The City of San Diego's Historical Resources Board followed with local designation in 2015, and the American Society of Civil Engineers separately recognized it as a local historic civil engineering landmark that same year. Today it sits preserved, unused for water but impossible to miss, a piece of North Park water tower San Diego history that survived through paperwork and patience rather than a fight.

Reuben Williams, the Man Who Invented San Diego Tourism

A generation before the tower went up, a man named Reuben Williams was doing something no one in San Diego had tried before. Williams was a Black entrepreneur working in a city that offered Black residents very few paths to formal employment. He found his own path.

Starting in 1889, Williams set himself up at the National City and Otay Railroad Depot and began offering guided tours of San Diego to arriving passengers, including cross-border excursions into Tijuana. He knew the city, knew its geography, knew what visitors wanted to see, and he knew how to talk to people. He became, by most accounts, San Diego's first professional tour guide, and he kept at it for 14 years, until his death in January 1903.

This wasn't a small thing. Tourism as an industry barely existed in the United States in any organized form at the turn of the 20th century. Williams wasn't following a model. He built one from nothing, operating in a time when Black entrepreneurs faced legal and social barriers that would have stopped most people before they started. He worked anyway, and visitors hired him.

Historians and local television programs, including Ken Kramer's long-running KPBS series *About San Diego*, have helped recover Williams' story from the edges of the historical record. Without that kind of attention, figures like Williams vanish entirely.

What North Park's Landmarks Actually Tell Us

Both of these stories share something, even though they belong to different decades. The water tower and Reuben Williams both survived because people paid close attention at a moment when it would have been easy to look away.

The tower's preservation came down to a historical society willing to do the research and file the paperwork that got it federal and local recognition. Williams' legacy is being preserved by historians and broadcasters willing to dig into records most researchers skip past. North Park water tower San Diego history is really a story about what a community decides to hold onto.

North Park today draws people because it feels layered. The bungalows, the old commercial strips, the parks, none of it arrived fully formed. It was built by real people solving real problems, sometimes brilliantly, sometimes just patiently. That texture is what makes a neighborhood worth knowing.

Frequently Asked Questions

When was the North Park water tower built and why?

The North Park water tower was completed in 1924 to solve a water pressure problem on the neighborhood's elevated mesa terrain. It held roughly 1.2 million gallons, filled during off-peak hours, and used gravity to supply the area during periods of high daytime demand.

Is the North Park water tower still functional today?

No. The tower was decommissioned in the 1990s once modern pumping infrastructure made elevated tanks unnecessary. It was formally recognized as a historic resource through nominations approved by the State Office of Historic Preservation (2013), the National Register of Historic Places (2013), and the City of San Diego's Historical Resources Board (2015), and it remains one of the most recognizable structures in the neighborhood.

Who was Reuben Williams and what is his connection to North Park San Diego history?

Reuben Williams was a Black entrepreneur who operated out of the National City and Otay Railroad Depot starting in 1889 and is recognized as San Diego's first professional tour guide. His story has been highlighted by local historians and featured on the KPBS program Ken Kramer's About San Diego, which brought renewed attention to his largely overlooked place in the city's history.
