A Discussion with Dan Carr and Miri Hackett
Consistent arena watering is the foundation of a safe, predictable riding surface, but most systems still rely on guesswork.
Watering an equestrian arena has always been one of the most difficult aspects of surface management. In a recent discussion, Dan Carr and Miri Hackett explored how arena surfaces evolved in response to this challenge—and why modern solutions must focus on arena watering consistency, drainage, and water efficiency rather than simply reducing labor.
Why Synthetic Surfaces Were First Introduced
The original purpose of synthetic and wax-based arena surfaces was not convenience, but consistency. These systems were first developed to eliminate the need for watering altogether. One of the earliest innovations came from Australia, where a solution was sought to maintain a consistent polo track without irrigation. That idea later made its way to England, where synthetic arena surfaces became widely adopted.
At the time, these materials offered a practical answer using what was available—but they also introduced new limitations that would later require further innovation.
Drainage Changed Everything
As arena design evolved, it became clear that drainage is fundamental. Without proper drainage, moisture levels vary across the arena, leading to inconsistent footing—hard in some places, deep or soft in others. This inconsistency creates uncertainty for the horse and increases injury risk.
The introduction of fiber-blended sand helped create structure in otherwise loose, angular sand. Combined with subsurface drainage, this allowed water to exit the arena rather than pool. However, irrigation consistency remained a major challenge.
The Problem with Traditional Irrigation Systems
In addition, many subsurface watering systems interfere with natural water movement, forcing more water upward than necessary—only for it to evaporate quickly under heat and sun.
A More Natural Approach to Arena Watering
Dan Carr explained that the most effective solution came from working with water rather than against it. HydroFlow technology, developed for Noviun Surfaces, uses closely spaced small-diameter piping to move water through the arena in a capillary action, delivering moisture directly to dry areas of the sand.
This system relies on a specially engineered fine fiber structure that acts like a true root system, allowing water to travel naturally throughout the surface. Unlike larger synthetic fibers, which block water movement, this approach creates uniform moisture and consistent footing across the entire arena.
Efficiency, Sustainability, and Measurable Results
The efficiency gains are significant. In peak summer conditions, a traditional arena may require 8,000–9,000 liters of water per day to maintain firmness. With the Noviun HydroFlow system, that number drops to 3,000–4,000 liters per day, while still achieving the same—or better—surface consistency.
That represents over 50% less water usage, with reduced evaporation and more stable moisture levels.
A Smarter Future for Arena Watering
Consistent arena watering turns a variable, weather‑dependent surface into a predictable training environment that riders and horses can trust day after day. By pairing data‑led moisture monitoring with a well‑designed irrigation layout, facilities can reduce water waste while keeping arena watering precise and repeatable.
Smart arena watering isn’t just about adding more water; it’s about applying the right volume, in the right place, at the right time. As discussed by Miri Hackett and Dan Carr, the future of arena surfaces lies in systems that deliver consistent footing, lower water consumption, and healthier environments for horses. Rather than relying on excess water or heavy synthetic materials, modern arena design must prioritize natural water movement, efficient irrigation, and long-term sustainability.
