„Water management is the catching, utilisation and seepage of rainwater that falls on a site".

In conjunction with modern supply systems it is possible to reduce waste water and drinking water charges, retain the water in the natural circuit and promote sustainable, decentralised water management.

The recovery of drinking water and the economical output of water over horticultural and agricultural areas is a further focus that is gaining in significance, in arid regions of the world in particular.

Contents of the "water management" education program


The demand for drinking water in Europe and the developing countries is growing constantly. At the same time, a large proportion of precipitation water that falls is drained away without being used, thus overloading the ditches and rivers. Floods and high waters are the consequence of this. In addition to these ecological factors, the costs of recovering and disposing of water are playing an increasingly significant roll and creating financial problems for many communities and public establishments.

Water management is an answer to the wasteful use of the valuable commodity that is water. The preconditions for the application and testing of water management are ideal at the Peter Lenné School of the OSZ Agrarwirtschaft (college for agricultural management). Sealed floor surfaces (plaster finish), a large number of roof surfaces and a high consumption of drinking water used to irrigate the areas utilised for agriculture and horticulture require a combination of widely varied processes for recovering and using water. It is a fundamental focus at the school and an inherent component of the education offered by the Regional Office for the Promotion of Industrial Occupations in Developing Countries.

The following course contents are taught within the framework of professional training, with consideration to the latest action and project-orientated education:

  • Configuration and functions of rooftop cultivations in order to reduce the accumulated volume of water
  • Configuration, functionality and maintenance of reservoir structures for capturing occurring precipitating water with example calculations
  • Planning, construction and maintenance of a multifunctional water system (water detention basin) with biological cleaning stage with repositioning plants for water purification
  • Construction and functionality of ground water wells for water recovery with pumps and supply technology
  • Methods for decentralised seepage (surface, shaft, trough, trench and combined installations) for ground water accumulation with applied calculations
  • Surface removal measures for improving water retention on plots with consideration to ecological factors
  • Planning, construction and operation of irrigation systems for irrigation and sprinkler water supply to land used for agricultural and horticultural purposes

Water management, together with solar thermal and photovoltaic systems, constitutes a future-orientated concept and is the way forward. It is a fundamental component of the ecological and sustainable management of rural and urban areas. The site of the OSZ Agrarwirtschaft offers related exemplary projects in theory and practice of a model nature for public institutions and private interested parties.
