Recreation fields demands the soil-waterair system regulation by drainage. A systematic pipe drainage is usually applied in this case. Parks and stand density recreation fields require such a construction of the drainage system that would prevent the roots of the trees and bushes from the drain pipes and water headers damage. In the case of stadiums it is recommended to apply a dense but relatively shallow drainage network. The network systems can different: parallel to the length of the sports ground, diagonal, or the so-called „envelope". The sod subsoil demands preparation. The bottom layer of the subsoil should be characterised by a high permeability of water. Spacing of the drains in parks, recreation and sports fields should be assessed separately for each object as soon as a given scheme of calculations is chosen. The schemes and methods can be found in professional handbooks. Drainage of the running trucks and rostrums can be performed by means of flumes placed on the outside. The flumes are connected with drain wells. The following example of calculations for the sports stadium MOS „AGRIKOLA” can serve as an illustration to the problem s stated above.

In order to ensure a good condition of recreation and the grass surface of sports fields, cultivation and irrigation are necessary. Irrigation under our conditions is necessary intervention. This results from our climate (frequent and long-lasting droughts and the properties of draining layer, which ensures a quick rain water discharge and has no water capacity, i.e. the possibility of absorbing and storing water). Under such conditions the only and reliable way to avoid water deficiency is irrigation. In the case of sports and recreation fields, sprinkler irrigation systems are recommended. Belt sprinkler machines are the most common. These are typical, modern devices used for a quick intervention sprinkler in a moderate climate. The advantages of a sprinkler machine are: concise construction, which allows for transport on a bicycle landing gear without a preliminary loading, readiness for use, full mechanisation, or even semiautomatic irrigation, suitability for sprinkler all crops and for all kinds of landscape. The right amount of irrigation application rate dose is assessed on the basis of operating pressure in the hydrant and the speed of pipeline with sprinkler. Another solution can be an automatic sprinkler system with a pop up sprinkler and computer controllers. The paper presents some schemes of recreation and sports fields irrigation.
