The embedment consists of bedding, side filling and initial and main cover. The quality of the embedment is significantly influenced by the installation conditions of the pipes. Other topics of this module include flowable fill for trench backfill, optimized installation methods and compaction tests.

After completing this module, you will have a sound knowledge of:

• Rules and regulations;
• Requirements for the embedment zone and compaction of the trench backfill;
• Process sequences of the open cut method;
• Influencing factors to ensure high execution quality on the construction site;
• Recognizing and assessing errors in construction.

The aspects of occupational health and safety that must be taken into account in the context of civil engineering work, especially in the construction of pipelines and sewers using the open cut method, are very diverse. They harbor a considerable potential for danger for those working on the construction site, but also for uninvolved persons.

After completing this module, you will have knowledge regarding:

• Risks and hazardous areas;
• Securing construction sites in traffic areas;
• Tools and equipment for safe working.

The construction of sewers is still often carried out in the form of open cut construction. Depending on the design, this results in different pipe-soil systems with different external loads on the sewer.

After completing this module, you will have a sound knowledge of:

• Rules and regulations;
• Requirements for planning, tendering and construction of the pipeline zone, the shoring and the components and building materials;
• Procedures for dewatering and
• Process sequences of the open construction method.

The construction of sewers is often carried out using the open construction method. Depending on the design, this results in pipe-soil systems with different external loads on the sewer. To understand these relationships, the soil mechanical and hydrogeological principles for characterizing the subsoil are explained.

After completing this module, you will have a sound knowledge of how:

• To differentiate between soil types;
• To identify the influences of grain shape and grain size distribution on the practical construction properties of the subsoil and
• To name the different appearances of water in the subsoil;
• To determine the water permeability of the soil for a constructional assessment of the soil.

This module focuses on the theoretical background and the practical conditions to be observed on the subject of welding of polyethylene pipes for gas, water and wastewater pipelines. A further focus is on the requirements to be considered in quality assurance and in particular the consequences of non-compliance.

After completing this module, you will have a sound knowledge of:

• Process steps of plastic welding;
• Consequences of non-professional plastic welding work;
• Necessary quality assurance measures.

This module is devoted to the pipe bursting as a special method of the replacement of pipelines. In addition, the module looks at the material and equipment requirements and the effects that pipe bursting has on the pipeline itself as well as its surrounding environment.

Upon the successful completion of this module, you will be able to:

• Describe the various pipe bursting processes,
• Identify the effects of pipe bursting on the surrounding environment, and
• Calculate the required minimum distances to the adjacent utilities and structures.

This module provides an overview of the historical development of water supply and sanitation and their meaning cultural development of mankind.

After completing this module, you will have knowledge regarding:

• Principal eras and
• Their contribution to the sanitary development.

Operational processes in the cleaning of drains and sewers have a high ecological and economic optimization potential. Activating this potential is the overall objective of this module.

After completing this module, you will have a sound knowledge of:

• Drawing up cleaning plans with special consideration of the structural condition of pipes and sewers and operating costs;
• Possibilities for saving operating costs;
• Differentiation of strategic approaches to cleaning.

This module focuses on the different possibilities for mechanical cleaning of sewers. In this context, a wide range of mechanically operating cleaning equipment is presented, and a practical impression is given.

After completing this module, you will have knowledge regarding:

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.

Large profiles and wastewater structures were manufactured on site in the past. Various methods and construction materials were used for this purpose. Professional maintenance of these structures requires a detailed understanding of the construction materials used and the manufacturing processes applied. This module provides the necessary basic knowledge for this understanding. Learning objectives:

After completing this module, you will have a sound knowledge of:

• Construction methods for large masonry profiles; • Typical damage to large profiles; • Special aspects of condition assessment for structures and large profiles; • Design and implementation of an extended investigation programme for condition assessment, classification and evaluation; • Design of an extended structural stability assessment.

Schächte übernehmen eine Vielzahl an Funktionen: Sie dienen zur Verbindung von Rohrleitungen, um die Richtung und/oder die Höhe zu ändern, um Zugang für Personal und/oder Ausrüstung zu ermöglichen und zur Be- und Entlüftung des Entwässerungssystems. Wie Kanäle und Leitungen müssen auch schadhafte Schächte saniert werden. Diese Lektion behandelt die Regulierung und den Austausch von Schachtabdeckungen.
