Irrigation of sports ground is essential to preserve the condition of the playground and facilitate sports activities. Unlike for private and public green areas, the dimensions of systems for sports grounds are designed even more accurately according to the relevant sport (Golf, Football, Rugby, etc.) and the composition of the turf, using retractable sprinklers that do not interfere with the game but allow an even and correct irrigation of the turf. The materials used are therefore different from those destined to private and public facilities, yet the type of application is very similar.
