| Course contents : | An integrated watershed management policy is required for any catchment, whatever urbanized or not. Both water quantity and quality must be included in this analysis. The course of Water supply and sanitation engineering provides an insight into the calculation methods and techniques for modern catchment management. It is composed of weekly lectures alternating either a theoretical part or a practical part. The latter one consists in an exercise, for which the student is expected to produce a personal report at the end of the lecture or at the beginning of the following one. Four topics are covered by the course of 10 h + 10 h and three additional ones are treated in the course of 20 h + 20 h. Topic 1 Introduction to water movement The two fundamental principles governing free surface flows, namely the mass balance and the momentum balance, are described. Those conservation principles are derived and explained in details. Characteristic flows in channels are also described. The corresponding practical part gives the opportunity to the student to get familiarized with the concept of uniform flow. Practical calculations of uniform water height are carried out on the basis of the Chezy formula. The influence of the cross-section shape is highlighted and extensively discussed. The role of the friction coefficient is also analysed. The major part played by the bed friction in free surface hydraulics is examined and presented as a concluding remark. Topic 2 Sewage systems The sewage networks and their calculation (diagram of Vicari) constitute the second main topic covered by the course. Both aspects of water quantities and water quality are addressed. The technical questions investigated are related to the arrangement of the sewers, the tanks and retention basins, the pumping systems as well as to the water sanitation. During the practical part, the student is required to completely design the sewage system of a small urbanized area by means of a Vicari diagram of the network. The diameter of each pipe must be calculated. The exercise leads to an important discussion related to the concept of non-linear transport during the hydrodynamic processes. Topic 3 Water training and adduction The third topic covers the study of various techniques of water engineering being used for collecting, transporting (adduction) and elevating ground and surface waters. The distinction between meteoric, surface (flowing and standing) and ground water is emphasized. Crucial questions of protection and improvement of catchment areas are analysed. The water adduction systems (aqueducts and conduits) are presented. The challenge of water elevation is examined: variation of dimension, positive-displacement pumps, water hammer, turbo-pumps, as well as protection devices. Finally, the storage tanks are considered through their capacity, exploitation and service supplied. The economic design of a storage tank for water supply in a town is performed during the practical work. Many realistic parameters are taken into account, such as the pumps maximum capacity, the water demand or the price of electricity, Topic 4 Rural and urban water supply The fourth topic covers the estimation of water demand, the calculation of the distribution system and the design of a whole water supply network. A case study of design of a simplified water supply network is entirely analysed in the practical part of the course. Both the case of a branched network and that of a meshed one are considered. In the latter case the Cross method is used. At last, all the pipes diameters are determined. | ||

| Course objective : | To give an insight into the modern engineering techniques for water training, adduction, distribution and sanitation. To provide simple calculation and design methods for each of those topics. | ||
| |||
| Organization : | Lectures are given during the second semester on Tuesday afternoon (from 2 PM to 4 PM). Weekly lectures, alternatively theoretical or practical. Practical exercises with individual reports. | ||
| |||
| Written notes : | Typewritten lecture notes available (235 pages). | ||
| |||
| Assessment : | The personal report of each practical lesson is noted individually.Written examination for the course 10 h + 10 h scheduled during the sessions in June or in September. The global note results from a weighted average of the notes obtained at the exam and for the practical work. | ||
