A new concept of large-scale urban irrigation

conference paper

en

This paper focuses on large-scale irrigation embedded in the urban landscape. During a century the city agglomerations are growing. There are enormous high temperatures on summer days. City plants have a lack of water and life in a city seems inhospitable. The main goal is to find a new concept of the large-scale irrigation system using a minimum of added energy. The system deals with rainwater harvesting and distribution in populated areas. Water is harvested from the roofs in a specific area near a possible place of accumulation. The pipeline system is located underground and protected against vandalism. The whole project should consist of an analysis of the zoning plan of the selected locality too. It focuses on the Czech Republic, especially of Brno. The design deals with the entire system, from the accumulation of harvested water to the distribution of watering to the root zone of plants. There are many technical solutions of accumulation systems (as a flexible collapsible bladder) or systems water distribution to plant roots. The proposed distribution network is calculated using the current known equations in the second part of the paper. The calculation is finished by choosing suitable dimensions of the pipeline network that can be used. In addition, the article suggests possible areas for the new planting of greenery in Brno. Finally, suitable trees for the urban landscape are mentioned.
