81640 - Urban Water Supply and Drainage Networks

Learning outcomes

At the end of the course the student owns the basic knowledge and principles for the design and management of hydraulic structures relative to water supply and drainage collection systems in an urban context and within a building.

Course contents

Hydrology and Drainage collection systems:

- Hydrologic cycle: precipitation regimes and data collection, gross and net precipitation, watershed water balance.

- Rainfall-runoff modelling; event-based models: rational method and linear storage model.

- Statistical analysis of extreme events, rainfall depth-duration-frequency curves.

- Overview of drainage systems, network types, rating curves in closed conduits.

- Design and verification of drainage systems.

- Sewage pipe materials and construction, lateral weirs and other special structures.

Water supply systems in an urban context:

- Water demand: population estimates, municipal water quantities and requirements.

- Water abstraction: spring water captation, groundwater capitation, captation from rivers and reservoirs.

- Water supply networks: design and analysis of water adduction and distribution systems: dead-end and loop networks.

- Pumping stations

- Storage reservoirs

- Water pipes (standards, materials) and other water supply system components.

- Water supply and distribution systems within a building.

Assessment methods

Candidates are required to sit a final test, which ensures the acquisition of the expected knowledge and skills.

The test is based on a written exam in which the use of notes or books is not allow, followed by an oral colloquium only if required by the Teacher based on the analysis of the written test. The exam includes both exercises, of the type of those presented during the course, and open questions concerning the theoretical aspects of the discipline.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents. To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject and a comprehensible use of technical language. A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject and/or logic failures in the analysis of the subject.
