The riding arena was built in Nuth by our Dutch dealer, „Paddock Maker“ company.
There is a new hall with a perfect riding surface, that’s been constructed in Sweden. Safety was first of all emphasized when planning this project, while the riding hall belongs to a riding school, where children learn to ride.

The HIT Active-Aqua horse arena irrigation system is based on comparable systems used in the areas of agriculture, gardening and landscaping, such as fruit and vegetable fields and grasslands. These industries have successfully relied on similar processes for watering. In order to achieve the same perfect and resource-conserving watering of the footing in horse arenas, we have optimized the most critical system components, the so-called drip lines. Our developers have then designed the patented HIT UNIVERSAL PLUS Draingrid as a vital component to complement our driplines. This grid system has protection against damage by the horse hooves and the buried irrigation lines of the footing in the arena. The physical properties of the sand, its capillarity that ensures ground-to-surface movement of the moisture through the sand’s particles, are the key to consistent moistening of the entire footing in the arena. As compared to dry or inconsistently irrigated footings, the grip and the anti-slip properties of the arena base improves substantially. Additionally, dust exposure for both horse and rider is reduced considerably since the moisture level can be fine-tuned.

How much water does the system use?Details
The system generally runs for 10-30 min. per day. With an average consumption of approx. 15 l (4 gal) per m2 per hour . The system can be adjusted according to evaporation, and desired moisture levels. 

How long and how frequently should the system run?Details
This depends on a variety of factors: Is it an outdoor or indoor arena? Is there direct sunlight exposure? What weather conditions prevail? What moisture level should the footing have?

How many drippers per square metre are needed?Details
Approximately 15 drippers per square metre are needed on average.

What level of sand moistness is recommended?Details
This depends on the situation on site and the particular needs of individual riders and horses.  Experience has shown, that no scientifically sound values can be derived for footing moisture levels. 

Does the system need several irrigation circuits?Details
Yes, when designing a HIT Active-Aqua Horse Arena Irrigation System, we like to divide the arena into several irrigation stations. Determination factors are the water supply either from waterlines

What is the difference between ordinary drip lines and the HIT Active-Aqua drip lines?Details
The drip lines are not simple lines with holes, as for traditional agricultural irrigation applications. The Hit Aqua Drip lines have an integrated diaphragm valve system,

How many times a day can the system be turned on?Details
The control computer allows up to four start times per day, each individually timed for every station. This results in tremendous flexibility of the irrigation schedule, allowing all-day consistent moisture for the footing. 

What are the thresholds that water has to be below of for the system to work properly?Details
Prior to installing a HIT Active-Aqua Horse Arena Irrigation System, an assessment of the available water is essential. Only if the relevant values are below the quoted maximum thresholds, a standard installation of the system is possible.

How can the system be cleaned?Details
If the water quality is good, it is largely sufficient to flush the system once per year by simply opening the ball valves at the end of the collector lines and flushing the system with water. Water with high calcium or iron content or desalinated water have to be flushed yearly with a low concentrated acid 

How much low-concentrated acid is used?Details
We will advise you of the correct amounts and concentration, which will enable effortless flushing of the irrigation lines: Service 

What does the construction of the drip pipes look like?Details
The drip pipes are not, as opposed to traditional agricultural irrigation applications, simple lines with holes. Rather, at every hole in the drip pipe, an integrated diaphragm valve is fitted. This valve opens and closes depending on water pressure, thereby achieving consistent water output into the footing across its entire area. The diaphragm valves are self-cleaning, in order to avoid any blockage of the opening by sand particles.

What water pressure does the operation of the HIT Active-Aqua horse arena irrigation system require?Details
The optimum operation of the system requires a minimum water flow pressure of 3 bar (44 psi) and a maximum flow pressure of 8 bar (116 psi). 

How can sand capillarity be measured, and what are the characteristics of a good sand?Details
To select a good sand for the footing of a horse arena and to water it efficiently, its capillarity is to be determined. This characteristic describes how fast moisture travels to the surface in the sand and will determine the correct type of sand to be used. Contact us for an analysis for us to determine the suitability of your current footing or we will recommend appropriate sand in your area. When we select new sand and/or any additives for the footing, we will make sure that the appropriate balance of the capillarity needed for irrigation and the properties of the sand match the riders’ and horses’ needs.

Is it possible to install the drip lines without the floor grid?Details
No, the HIT Active-Aqua horse arena irrigation system only works with our patented HIT UNIVERSAL PLUS Draingrid. Its design ensures full protection of the drip pipes against any overstrain or damage by the horses’ hooves. Only the dedicated grid design ensures an effective water distribution throughout the riding arena floor. 

Is it possible to drive over the grid floor while filling it?Details
Wheel loaders, yard tractors, bobcats can drive on the grid provided it is completely installed and grids are fully filled. Once the grids are laid, the filler sand has to be brought in from the outside and gradually progressing towards the other end of the arena filling the grids. At this stage one can drive over the grid floor.

What are the main advantages of the HIT Active-Aqua horse arena irrigation system?Details
A consistent and even moisture penetration throughout the entire arena floor is substantially more efficient with this system. No more irrigation overlaps, pooling water or dry areas. The arena can be used during the watering cycles- no down time. No water loss due to evaporation. Water is used efficiently and economically only on the footing as wall, fence, and side boards remain dry.

Can individual drip lines be repaired?Details
Yes. Should a drip line be defective, the above lying grid is removed- without tools , giving access to the driplines to be replaced. The grids are then easily reinstalled.

What is the applicable warranty term?Details
The HIT Active-Aqua horse arena irrigation system drip lines have a 10-year warranty, provided the water properties are under the relevant thresholds. All other hardware we ship has a 2-year warranty.
