Oct 25, 2013 Course This course includes tutorial services and a final examination. 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 course consists of 5 modules covering the following topics:

Mar 07, 2014 Course This course includes tutorial services and a final examination.
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 course successfully, and stress-free within four weeks, we recommend following the following agenda which distributes the different modules evenly over the entire period:
1st week: Module: Introduction, Fundamentals and geotechnical investigations, Pipe jacking (Part 1)
2nd week: Module: Pipe jacking (Part 2), Microtunnelling
3rd week: Module: Jacking pipes, Jacking steering
4th week: Module: 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.

May 21, 2014 Course This course includes tutorial services and a final examination.
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 course consists of 7 modules:
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

Sep 11, 2015 Course This course includes tutorial services and a final examination. 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:
