THT261 Introduction to water and wastewater systems

The purpose of this course is:

1. To build an understanding for water and wastewater systems, i.e. provide an introduction to and overview of all the main elements that make up urban water and wastewater systems, their functions and how they work together.
2. To provide the most necessary foundation for planning, dimensioning, operation and maintenance of transport systems (pipe systems and associated facilities) for water, wastewater and stormwater.

Topics covered in the course include:

• Introduction with a historical overview of the development of the water and wastewater sector in Norway
• Basics: Hydrology and hydraulics for water and sewage (partly repetition)
• Hydraulics: Selected new topics in hydraulics (water hammer, unsteady pipe flow)
• Drinking water: Water sources and water intake, water demand and water consumption, transfer and distribution of drinking water, leakage problems, introduction to modeling of water supply networks (EPANET)
• Wastewater: Quantity and composition of wastewater, collection, transport and discharge of wastewater, problems related to infiltration/inflow, leakage and overflows
• Stormwater: General introduction to stormwater management, calculation of stormwater runoff that enters pipelines
• Groundwater for water supply and as a recipient for wastewater
• Pipeline technology: Material properties, loads on pipes and manholes, trench design and construction techniques, anchoring, trenchless rehabilitation methods
• Management, operation and maintenance of transport systems for water and wastewater, condition assessment and rehabilitation planning
• Relevant regulations and guidelines, organization and financing of water and wastewater, municipal planning processes for water and wastewater, project execution for water and wastewater

Knowledge:

• The student has knowledge about the structure and function of the main elements of a modern water and wastewater system, from the intake of raw water to the discharge of wastewater to the recipient
• The student has detailed knowledge of transport systems for water, wastewater and stormwater which is necessary for the planning, dimensioning, management, operation and maintenance of these systems, including knowledge of pipeline engineering and construction engineering
• The student has knowledge of the Norwegian water and wastewater sector, including history, regulations and guidelines, organisation, financing and important challenges in the sector

Skills:

• The student can carry out calculations for basic analysis and hydraulic dimensioning of transport systems for water, wastewater and stormwater
• The student can build and run a simple model in EPANET for the analysis of drinking water networks
• The student can carry out simple planning of new water and wastewater systems
• The student can carry out simple planning of operation, maintenance and rehabilitation of existing water and wastewater systems
• The student can make assessments related to the choice of materials and the design of pipe systems for water and wastewater

General competence:

• The student has experience with and an understanding that the basic science courses in the civil engineering studies have practical relevance
