Irrigation of sports grounds is fundamental to keep the field in perfect condition for the sports activity.
The system varies according to the composition of the surface, whether natural grass, clay or the artificial surfaces which are increasingly popular in the past years and often requested by major international sports federations.
For natural grass fields, the system must deliver as homogeneous an irrigation as possible. In this way the lawn will be uniformly watered, without areas of standing water or the converse, areas insufficiently watered and thus subject to drying out. It is important that the system is minimally invasive, in that during the sports activity any sprinklers in the centre or around the edge of the field must disappear completely to avoid the risk of injury to players.
For clay courts, the main use of irrigation is to maintain the ground at a constant level of moisture, ensuring it always retains its compact texture during use.
In synthetic grass surfaces, the role of irrigation is to maintain the compactness of the layer of sand beneath the artificial turf, and to maintain a constant level of moisture to ensure that the playing surface is smooth and even.
