This subject introduces the student to the engineering design of water and sanitary services in buildings. It encompasses the design, installation and regulatory requirements of common water and sanitary systems as well as an introduction to water quality assessment and modern renewable technologies.
MAINS WATER SERVICE: Direct & Indirect mains water pumping systems, Pipe & pump sizing principles, break tank sizing, Pump control, Local water authority policies and requirements, Water quality, designers responsibilities, backflow prevention, practical aspects of hydraulic system design in accordance with current British Standards and European Norm standards.
COLD WATER SERVICE: Storage capacity requirements, probability or usage ratio, simultaneous demand units, cold water supply systems using available static head, static head pipe sizing, identification of index circuit, assessing pressure available at the branches and sizing branches, sizing the cold water storage tank(s), chlorination and disinfection of water services systems, practical aspects of water services system design in accordance with current British Standards and European Norm standards.
HOT WATER SERVICE: Storage capacity requirements, Regeneration period, probability or usage ratio, load units, hot water supply systems using available static head, pumped systems, pumped & static head water services pipe sizing, identification of index circuit, assessing pressure available at the branches and sizing branches, sizing the hot water storage vessel, centralised & localised storage, use and sizing of indirect gas fired hot water generators, use and sizing of heat pumps for generation of domestic hot water, sizing the secondary return, hot water storage temperatures, legionaries disease, pipework materials & fittings in accordance with current British Standards and European Norm standards.
ABOVE GROUND DRAINAGE: Single, ventilated stack systems & applications, traps, importance of water seal in traps, loss of water seal, sanitary pipework sizing, practical aspects of sanitary services system design in accordance with current British Standards and European Norm standards.
