Irrigation technology presents a special challenge for the structural design and subsequent construction, both for the landscape architect and for the gardening and landscaping company carrying out the work.

The spectrum for irrigation systems in open spaces is very broad. It ranges from private gardens to public urban areas and parks. Furthermore, irrigation systems ensure the use of living greenery indoors, in vertical structures as well as on structures without ground closure. Likewise, certain green spaces used for sports such as soccer, golf, tennis, and horseback riding require irrigation of green spaces that is appropriate for the use and vegetation. This module teaches the basic construction methods of irrigation systems and the fundamentals of irrigation equipment selection, sizing, installation and maintenance. Students will be able to grasp more complex engineering relationships in irrigation appropriate to species and site and evaluate engineering principles related to available water quantity and coordinated application methods. They will be able to select appropriate technical infrastructure and present this detailed technical planning in engineering terms.

Basic knowledge of woody plants and perennials as well as construction techniques

Students who have successfully studied this module have basic knowledge in the field of irrigation technology. They know the types of water application and the civil engineering basics with regard to pipeline construction and technical structures.

Students who have successfully studied this module will be able to combine the various components for irrigation systems on an object-specific basis. They recognize the basic requirements of the respective object and can describe the necessary construction principles.
They are able to represent simple building constructions of irrigation technology in drawings and to formulate them in a performance specification.

Students who have successfully studied this module will be able to assess the water requirements of perennial and woody plantings and design irrigation systems to meet these requirements. They can justify the basic requirements, recognize problems and examine possible solutions.

Students who have successfully studied this module apply the acquired skills within the framework of execution planning, construction design, construction site management, construction site control or construction site supervision. They independently carry out construction tasks in irrigation technology from civil engineering design to implementation planning. You will be able to discuss planning approaches with third parties and work out advantages and disadvantages.

Students who have successfully studied this module will be able to technically design simple irrigation systems, interpret designs, check their feasibility and roughly dimension individual technical components. They are able to face innovations and to integrate these innovations into existing and future planning. They are able to face the requirements arising from climate change and to develop resource-saving approaches to solutions.

Students who have successfully studied this module will review and evaluate their own and external irrigation engineering design problems.
They recognize design approaches and can diagnose construction problems. They modify their own construction engineering tasks by comparing design tasks and can contrast and evaluate the solution approaches.

Students who have successfully studied this module will be able to sustainably irrigate open spaces, create ecologically sound and resource-efficient plans, and present them professionally to an expert audience as well as to the building owner.
