public water infrastructure, and are under the care of the building owners or property management companies. This theme is aimed at building up visitors' awareness of the need to keep internal plumbing systems in good and clean condition. Visitors will be encouraged to join the Quality Water Recognition Scheme for Buildings for promoting the proper maintenance of plumbing systems in buildings. Moreover, the importance of water metering and billing will be emphasised as a key measure to monitor excessive and unnecessary use of water. Meter testing services will be instructed to enhance public confidence in the metering accuracy. 12.4 Water Pressure & Level 水壓與水高 An interactive exhibit to demonstrate the strength of water pressure related to the height of water from level difference but not volume difference. Two containers of equal volume but different shape with outlets at three different levels (can have each with two sets of outlet with one opened horizontally and the other vertically upward). 12.5 Water Leakage Detection – In Water Mains of Supply Network Using Pressure and Volume Using meter to interactively detect changes in water pressure when flows of water are changed. Will show also the standard range of acceptable water pressure in a typical supply and home system. Interactive exhibit showing how to use PMA (Pressure Management Area) to reduce leakage of water in transmission pipes and DMA (District Meter Area) to detect leakage pipes A tube of recirculating water with a number of outlets that visitors can open and close, with a meter measuring the change of water pressure during the process; and can be used for detecting water leakage. Including new technology to improve pressure management and detection of leakage. 12.6 Water Leakage Detection – Inside Buildings 樓宇滲水偵測 Interactive exhibit showing how to identify sources of leakage of water inside buildings Using infrared photography, dyes and other techniques 12.7 Waterworks at Home 家居水工程 Showing the types of waterworks at home that must be done by a licensed plumber and minor work that can be done by oneself With sample of materials and video of work
