D-06 - Maintenance of drain and sewer systems - Cleaning II

300.00 EUR plus VAT / 16 hours within 4 weeks

Cleaning is one of the most important maintenance measures when it comes to ensuring a continuous performance of drainage systems. This module expands on the topics covered in module "D-05 cleaning I", by providing further knowledge on the applications and limits of flushing methods, mechanical cleaning methods and special methods, such as physical and chemical sewer cleaning. Discussed are both the accessible and non-accessible lines, as well as pressure lines. It concludes with providing constructive solutions for the minimization of solids entry into the sewer system, with the aim of preventing the formation of deposits and hence the reduction of cleaning efforts and frequencies. The module consists of 5 lessons covering the following topics: • Flushing methods • Mechanical and Miscellaneous methods • Cleaning of large profiles • Cleaning of pressure lines • Constructive design measures for the reduction of deposit

D-21 Utility Tunnelling

600 € plus VAT / 30 h in 4 weeks

The installation of supply and disposal lines is still mostly performed using the open cut method consisting of digging a trench, laying the pipe under the protection of shoring, and subsequently backfilling the trench. Given the many disadvantages associated with this method along with the growing environmental awareness of the population, it is imperative that trenchless technologies be taken more strongly into account in the planning and construction of pipelines and utility networks. The learning module "Utility tunnelling" is divided into seven lessons, each focusing on a specific topic. The contents of the individual lessons are complemented with a link to more detailed literature. This literature is not relevant to the exam, but serves as a reference for a more in depth look. The module "Utility Tunnelling" ends with a final examination, which references all of the modules content. In order to complete the module successfully, and stress free within four weeks, we recommend following the following agenda which distributes the different themes evenly over the entire period: 1st week: Lessons: Introduction, Fundamentals and geotechnical investigations, Pipe jacking (Part 1) 2nd week: Lessons: Pipe jacking (Part 2), Microtunnelling 3rd week: Lessons: Jacking pipes, Jacking steering 4th week: Lesson: Starting and target shafts, Final exam This schedule is only a recommendation, as it is of course up to you when and how you work through the curriculum.

D-15 - Replacement of sewers and drains

600.00 EUR plus VAT / 30 hours within 4 weeks

Replacement refers to the installation of new sewers and drains in place of existing pipelines, where the new pipeline takes over the functions of the old sewer or drain. The replacement process is subdivided into three methods: "open cut method", "semi open cut method" and "trenchless method". The focus of this module is the trenchless replacement method of pipelines by the means of pipe bursting, gallery techniques, and pipe extraction. In addition to the replacement method and process description this module discusses the areas of application and limits, the advantages and disadvantages as well as possible rehabilitation errors and options for quality assurance. The module combines this knowledge into 7 lessons: 1. Pipe bursting basics 2. Pipe bursting 3. The welding of plastic pipes 4. Pullback of pipelines 5. Gallery techniques 6. Pipe extraction 7. Geotechnical and hydrogeological principles

D-01 - Wastewater collection systems and their significance in water management

400.00 EUR plus VAT / 30 hours within 4 weeks

The overall challenge of each generation that takes over responsibility for a drain and sewer system is to construct new wastewater collection systems or to expand already existing ones, and to inspect, repair, renovate and replace, or rather adapt, them to the strengthened groundwater and water protection standards. The primary objective of all measures has to be the creation of a fully operational and long lasting drain and sewer system. This is created to transport the wastewater safely and efficiently between the producers of wastewater and the wastewater treatment plant. Furthermore, rehabilitation and maintenance work should be easy to carry out. Thus, sound expertise is required in planning, construction, operation and maintenance. This module teaches the most elementary basics needed for a comprehensive design of an integral drain and sewage framework. It includes: • Water cycle (transport and storage of water) at a global and regional level • Interactions in the urban water cycle as well as effects on groundwater and waters • Facts and figures regarding the global water demand and water exploitation • Historical development of wastewater collection systems • Significance of wastewater collection systems in the overall context of water management • Cycle of resources (water collection, water distribution, wastewater discharge, wastewater treatment) • Terms • Requirements for wastewater collection systems regarding their functionality and performance capacity • Types of wastewater collection systems • Structure and limiting conditions of sewer systems • Pipes – cross sectional shapes, dimensions, fittings • Pipe materials • Pipe connections • Shafts and structures • Road gullies, gutters (Catch basins) • Construction methods • Type and design of the bedding • Overview of typical intra-urban line types and underground infrastructures • Introduction to the integral sewer management • Performance capacity aspects of a drain and sewer system, assessment of the performance capacity by comparing given data to performance capacity requirements, development of a design and its implementation • Design principles • Surface water treatment, use and percolation • Choice of a drain and sewer system

D-02 (US) Installation of water pipes, drains and sewers using the open cut method

800.00 USD exclusive of VAT / 40 hours within 4 weeks

The installation of water pipes, in particular, drains and sewers is worldwide in large part performed using the open cut method. This at first glance "simple" construction method is actually highly complex when used in urban areas and at large depths. The numerous boundary conditions, shoring-, and installation systems require extensive technical knowledge in order to ensure a high quality workmanship. The module consists of 5 lessons on the following topics: 1. Geotechnical and hydrogeological Principles 2. Utility Trench Construction 3. Embedment of Piping 4. Installation of Pipes 5.
