Completion of the progress requirements of Level HE2 and Modules ENG1049 & ENG2018

To introduce students to issue of water quality, sanitation and health

To make students aware of the importance of raw water sources and surveillance techniques

To introduce students to water treatment processes for potable supplies, including related physical, chemical and microbiological aspects

To make students aware of reservoir storage and management techniques

To introduce students to the assessment of demand, supply network design and service reservoirs

To provide students with the basic analytical tools for assessing the hydrological cycle from rainfall to runoff, river flow, and sediment transport

By the end of the module, it is intended that students will be able to:

 ·       understand the principal issues of environmental health in relation to water supplies

 ·       understand the broad aspects of raw water sources and quality

 ·       understand the broad principles of water treatment

 ·       understand the broad principles of demand assessment and supply network design

 ·       assess the rainfall runoff characteristics for different terrain using standard meteorological data and methodologies

•  analyse steady and unsteady flows in river channels including sediment transport
