HydroCourt is a self-regulating system that is fully adjustable to player preference and designed to water your Har-Tru tennis court from below the surface.

HydroCourts are constructed with six individually controlled cells. Each cell is monitored by a separate water-filled control box. Water enters the control box and flows through pipes to cells lined with a chemical-resistant 20 mm thick hyperlastic liner.

As the water level in the control box rises, the water level under the court also rises. You control the amount of moisture in the court surface by adjusting the water level in the control box up or down. It's that simple.

Key Features

No down time. HydroCourt maintains optimal moisture at all times from below so you never have to shut your court down for watering.

Consistency. Unlike most above-ground irrigation systems, water coverage is uniform and even, keeping traction safe and consistent.

Water savings. HydroCourt provides only the amount of water needed to keep the court moist. This can save up to 60% of water usage when compared to conventional irrigation.

Reduced maintenance. Constant moisture keeps the surface firm and substantially reduces the amount of brushing and rolling needed to properly maintain the court.

Reduced cost of ownership. Consistent water prevents erosion and this lessens the amount of Har-Tru that needs to be replaced annually and over time. 

Choosing the HydroCourt system means there is no sprinkler system to maintain.

HydroCourt Performance Tips 

  •     When optimum water level is achieved, mark that level in your water control box for future reference.
  •     Use aggressive tools, such as the Har-Tru Gator Rake, daily for grooming the court.
  •     With a simple pull of a plug, HydroCourt can be drained. This is helpful in tournament situations where there is a lot of rain, and it makes winterization easy.
