Planning HydroFlow at the Arena Construction Stage
The irrigation system should be considered early when planning new equestrian arena surfaces. Installing it as part of the arena construction process allows the base, drainage, irrigation network and riding footing to be designed as a coordinated system.
A typical HydroFlow installation includes the existing ground, a prepared base, drainage infrastructure, the irrigation network and a suitable separation layer beneath the Noviun riding surface. The exact specification depends on the site and project requirements.

Planning these elements together during arena construction helps establish the correct relationships between water delivery, upward movement, drainage and surface performance.
For existing arenas, the suitability of a retrofit depends on the current base, drainage, footing and available installation access. A technical assessment can establish whether HydroFlow can be integrated effectively.
Noviun Surfaces works with installation partners to support arena construction projects from planning and groundworks through to drainage, irrigation and surface installation.

HydroFlow for Indoor and Outdoor Arenas
HydroFlow can be used in both indoor and outdoor riding arenas, although their watering requirements can differ considerably.
Outdoor Arenas
Outdoor arenas are exposed to sunlight, wind, temperature changes and rainfall. These factors can cause substantial differences in moisture levels across the same surface.
HydroFlow’s controlled water distribution and zoning capabilities are particularly relevant in these environments. Areas exposed to stronger sunlight can be managed according to their moisture requirements, while shaded areas can receive less water when appropriate.
This can help arena managers maintain more consistent footing through changing weather conditions while reducing unnecessary water consumption.
Indoor Arenas
Indoor arenas are protected from direct rainfall and many external weather influences, so their moisture requirements are often lower and more predictable. Ventilation, temperature, usage and the composition of the riding surface still affect how quickly moisture is lost.
Depending on the facility and its conditions, an indoor arena may require only short irrigation cycles, potentially around 10 minutes every other day in some installations. This is an example rather than a universal schedule. Actual watering intervals should be determined by the arena’s moisture readings and performance requirements.
HydroFlow’s programmable controls allow watering schedules to be adapted to the individual facility, helping avoid unnecessary irrigation while supporting suitable footing conditions.
How Noviun Surfaces and ArenaMend Approach Arena Irrigation
Noviun Surfaces and ArenaMend share a focus on natural fibre footing and more considered arena water management. Noviun Surfaces offers natural fibre arena surfaces and HydroFlow subsurface irrigation, while ArenaMend is part of the wider network bringing these surface solutions to the market, including applications in the United States.
Together, the surface material and irrigation system address two connected aspects of arena management: how the footing behaves under the horse and how moisture moves through it.
Noviun Fibre provides the natural fibre component, while HydroFlow manages water delivery beneath the surface. When the system is correctly designed and maintained, this combination aims to support consistent footing, effective dust management and reduced water consumption.
For US arena owners, ArenaMend offers a route to explore these natural fibre surface solutions and the ArenaGreen application, which uses Noviun Fibre technology.
Learn more about the available solutions through the Noviun Surfaces website or the ArenaMend website.
Building Better All-Weather Arena Surfaces
The performance of an arena depends on how its different components work together. The footing material, base construction, drainage, irrigation and maintenance programme all influence the conditions horses experience during training and competition.
HydroFlow introduces a subsurface approach to irrigation, using controlled water delivery and natural capillary movement to help manage moisture throughout the riding surface. When paired with Noviun Fibre, it offers an approach to water management designed around the properties of natural fibre footing.
For arena owners considering new equestrian arena surfaces or looking to improve an existing riding arena footing, understanding irrigation at the planning stage can help inform decisions about arena construction, maintenance and water use.
The goal is a riding surface that performs consistently, uses water responsibly and supports the needs of horses and riders throughout the year.
