This subject introduces the student to water & sanitary services in buildings and water quality. It encompasses the design, installation and regulatory requirements of common water & sanitary services, along with laboratory experiments on water quality. This module aims to enable the students to understand the fundamental principles underlying water & sanitary services in buildings. This module will help the students to develop engineering skills in designing water and sanitary services for buildings.
Topics covered include:
MAINS WATER SERVICE: Water treatment systems, Direct & Indirect mains water pumping systems, Pipe & pump sizing principles, break tank sizing, Pump control, Local water authority policies and requirements, water quality and sustainable development goals, designers responsibilities, backflow prevention, mains water supplies to fixed first aid fire fighting-wet & dry risers, fire hydrants, fire hose reels. Storage capacity requirements and sizing considerations, practical aspects of system design in accordance with current British Standards and European Norm standards.
COLD WATER SERVICES: 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 SERVICES: 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.
This module will be delivered as a series of lectures, discussions, class based problem-solving exercises and laboratory based water quality experiments.
