Course content

The course focuses on methods for planning, dimensioning, designing, management and maintenance of water, wastewater and stormwater pipe networks and storm water systems. The main areas are: a) development of good pipe systems for drinking water, storm water and wastewater, including sustainable and smart pipeline systems with a very long life; and b) planning of how we can manage stormwater in a sustainable and climate-adapted way to prevent pollution and protect cities from flood risks. The course is divided into four main thematic areas:

The first theme introduces the impacts of climate change on water, stormwater and wastewater pipe networks in cities.

The second theme focuses on models for dimensioning pipe systems for water, wastewater and storm water.

• Hydrology: rainfall intensity, rainfall-runoff models, rainfall statistics, frequency analyses, climate change, terrain analyses, infiltration and other field processes, climate effects in Norway, runoff conditions.
• Open Channel flow: Flow mechanisms, energy & hydraulic gradelines, design of channels, and culvert hydraulics.
• Stormwater management: stormwater as part of the cityscape, chemical and microbial pollution from stormwater, choice of conventional versus nature-based stormwater management, local and open management of stormwater in urban areas, e.g., infiltration techniques, dimensioning, equipment and operation of ponds, open waterways, gutters and canals for storm water.
• Water supply: Dimensioning of large networks. Projection of water demand. The drinking water network with associated pumps, valves and other equipment. Choice of wiring material. Water quality.
• Wastewater network: Collection of wastewater in drainage networks with pumps, sumps, ditches, etc. Recipient. Choice of pipe material.

The third theme concerns the maintenance and rehabilitation of wiring networks. Principles of condition analysis, condition assessment, inspection techniques, leak detection, monitoring and maintenance and rehabilitation techniques. Risk identification and qualitative risk management.

The final theme introduces digital tools and smart systems for modelling, simulating and monitoring water, stormwater and wastewater pipelines and handling systems. Use of digital tools and programming for simulating pressure, water demand, pumps, leaks and water quality in the water distribution network. Use of digital tools for assessment of the stormwater and wastewater network with regard to capacity, pump, overflow and pollution. Use of digital tools for simulating nature-based stormwater systems. Overview of existing technologies (sensors and IoT) for monitoring water, stormwater and wastewater pipe networks.
