Module details for Water Engineering and Drainage Systems


This Module covers the application of civil engineering hydraulics, drainage systems and environmental engineering.


The aim of this Module is to extend and develop understanding of hydraulics and environmental engineering.

Learning Outcomes

By the end of this module the student should be able to:

1.  Analyse and design open channel and hydraulic systems.

2.  Analyse and design simple foul and storm runoff drainage networks.

3.  Apply some of the principles used in the abstraction and treatment of water.

4.  Design unit processes for the abatement of water pollution.


Indicative Content

1 Uniform flow in open channels

Frictional resistance formulae for steady uniform flow in open channels. Channel design considerations, including optimum shape of cross-section for uniform flow in open channels.

2 Non-uniform flow in open channels

Specific energy and alternative depths of flow. Occurrence of critical flow conditions. Flow over a broad-crested weir. Classification of water surface profiles. The hydraulic jump and the use of critical depth in flow measurements. Design of spillways.

3 Drainage systems

Combined and separate sewer systems. Urban storm water pollution control. CSOs. Sustainable Urban Drainage Systems. Estimation of foul and storm flows. Design of simple systems for foul and surface water.

4 Water pollutants and pollution control regulations

Fate of water pollutants in rivers and lakes. Quality Standards, UK and EU Directives. Fundamentals of self- purification. Setting standards to meet quality standards. Models used as quality predictive tools. Streeter-Phelps equation.

5 Water treatment

Treatment requirements for various sources of water for potable use. Detailed consideration of coagulation, flocculation, sedimentation, filtration and disinfection processes. Design of rapid sand filters. Sustainability considerations.

6 Wastewater and urban storm runoff treatment

Detailed consideration of sustainable urban drainage systems (SUDs) for the treatment of urban storm runoff. Introduction to domestic wastewater treatment; detailed consideration of sedimentation and biological processes. Sludge handling, treatment and disposal. Sustainability considerations.

Guidance notes

SCQF Level - The Scottish Credit and Qualifications Framework provides an indication of the complexity of award qualifications and associated learning and operates on an ascending numeric scale from Levels 1-12 with SCQF Level 10 equating to a Scottish undergraduate Honours degree.

Credit Value – The total value of SCQF credits for the module. 20 credits are the equivalent of 10 ECTS credits. A full-time student should normally register for 60 SCQF credits per semester.
