	Objectives
	THE COURSE AIMS TO PROVIDE WORKING AND DESIGN PRINCIPLES OF MOST COMMONLY USED WATER WORKS IN BUILDINGS, WITH PARTICULAR ATTENTION TO THE HYDRAULIC APPLIANCES. THEORETICAL TOPICS ARE SUPPORTED AND SUPPLEMENTED BY CARRYING NUMERICAL EXERCISES AND BY DEVELOPING AFFORDABLE TECHNICAL-ECONOMIC SOLUTIONS TO BE PRESENTED IN TWO PROJECTS (ONE FOR SEMESTER).

	Prerequisites
	IN ORDER TO SUCCESSFULLY FULFILL PREDETERMINED GOALS, KNOWLEDGE OF MECHANICS OF CONTINUUM SYSTEMS IS REQUIRED.

CLASSROOM PROJECTS
PRELIMINARY DESIGN OF A FIRE-FIGHTING WATER SYSTEM OR PRELIMINARY DESIGN OF HYDRAULIC EQUIPMENT SYSTEMS IN BUILDINGS.
PRELIMINARY DESIGN OF A DRAIN SYSTEM FOR CONVEYING URBAN RUNOFF FROM BUILDINGS.

	Teaching Methods
	THE COURSE CONSISTS OF THEORETICAL LESSONS, CLASSROOM AND LABORATORY EXERCITATIONS. DURING THE ACTIVITIES IN THE LOCAL LABORATORY, STUDENTS, SPLIT IN GROUPS, WILL DEAL WITH THE PROJECT OF HYDRAULIC SYSTEMS AND EQUIPMENT’S. AS GUEST IN THE LOCAL HYDRAULIC LABORATORY, THE STUDENT CAN OBSERVE AS WELL FREE SURFACE FLOW PROBLEMS.

	Verification of learning
	THE ASSESSMENT OF ALL GOALS ACHIEVEMENT WILL BE DONE THROUGH A WRITTEN TEST, WITH QUESTIONS BOTH OF HYDRAULICS AND HYDRAULIC ENGINEERING, AND AN ORAL EXAMINATION IN WHICH, IN ADDITION TO THE ANALYSIS OF THE THEORETICAL CONCEPTS, THE PROJECTS ASSIGNED DURING THE YEAR ARE DISCUSSED. TO PASS THE EXAM, THE STUDENT MUST DEMONSTRATE TO HAVE UNDERSTOOD ALL THE MAJOR CONCEPTS TOPICS AS WELL AS TO PROPERLY APPLY THEM. FINAL MARK, OUT OF 30 (30 CUM LAUDE IN THE CASE OF FULL MARK WITH DISTINCTION), DEPENDS ON THE LEVEL OF COMPETENCE BEING ACHIEVED, ON THE QUALITY OF THE WRITTEN AND ORAL EXAMINATION AS WELL AS ON THE MATURITY GAINED ON THE COURSE CONTENT (PERSONAL JUDGEMENT).
