1 Water Efficiency Labelling Scheme by Sam Y S WONG Engineer Water Supplies Department The Government of the Hong Kong Special Administrative Region of the People s s Republic of China 1 1

2 Basic Information Area: approximate 1,100 km 2 Population: approximate 7million Climate: Subtropical Rainy seasons: April September Average annual rainfall: 2,380 mm Fresh water consumption in 2009 : 952 million cubic metres (mcm) 2

3 Drought in 1963 Most Severe in Last Century 3

4 Hong Kong s Water Supply History Year No. of Days with Full Supply War Time (No Records)

5 Water Supply Situation in Hong Kong Water Consumption (x 1000 million m 3 ) Year Dongjiang Water Local Catchment Yield

6 Current Water Supply Arrangement Dongjiang (DJ) water : 70% 80% of demand Local yield : 20% 30% of demand Planned ultimate DJ annual supply of 1,100 mcm will be sufficient to cope with the projected demand in 2030 and beyond 6

7 7 Total Water Management (TWM)

8 Total Water Management (TWM) To better prepare Hong Kong for the uncertainties of climate change To enhance Hong Kong s role as a good partner with other cities in PRD in promoting sustainable use of water resources 8

9 TWM Strategy The TWM Strategy is to manage water demand and supply in an integrated, multi-sectoral and sustainable manner The TWM Strategy: Put emphasis on containing growth of water demand through conservation Strengthen water supply management 9

10 Water Efficiency Labelling Scheme (WELS) 10

11 Water Efficiency Labelling Scheme (WELS) WELS is one of the water conservation initiatives of TWM strategy WELS aims to cover common types of plumbing fixtures and water-using appliances Help consumers to select water-saving appliances Indicate the level of water consumption and water efficiency rating Voluntary participation All manufacturers, importers and other related parties are welcome to join the WELS 11

12 Water Efficiency Labelling Scheme (WELS) WELS on showers commenced in Sep 2009 WELS on Taps commenced in Sep

13 13 WELS on Showers

14 Scheme Scope Cover new showers imported to or manufactured in Hong Kong but excluding second-hand products, products already in existing use, under trans-shipment or manufactured for export, etc. Applicable to the showers listed below: showerheads installed to fixed arms/concealed pipes in the wall or ceiling; showerheads installed to pivotal arms; and Hand-held showers 14

15 Testing Method and Standard Reference to Australian/New Zealand Standard No. AS/NZS 3662:2005 Performance of Showers for Bathing with Amendment No. 1 Testing items Mean spray spread angle Temperature drop Flow controller endurance Nominal flow rate 15

16 Performance Requirements To meet the following requirements Parameter Mean spray spread angle Temperature drop Flow controller endurance Requirements Between 0 0 and 8 0 Not exceed 3 0 C Within ± 1 l/min of the nominal flow rate after about 10,000 on-off cycles 16

17 Labelling System WSD to rate water efficiencies of the showers are rated to different grades based on their nominal flow rates 17

18 Water Efficiency Label Full and simplified versions 18

19 WELS on Showers As at 25 November 2010, 119 showers have been registered under the scheme. Grade 1 93 nos. Grade 2 11 nos. Grade 3 15 nos. 19

20 20 WELS on Water Taps

21 Scheme Scope Cover new water taps imported to or manufactured in Hong Kong but excluding second-hand products, products already in existing use, under trans-shipment or manufactured for export, etc. Applicable to the water taps of hot and cold water mixing or non-mixing type installed at bathroom/toilet washing basins and kitchen sinks and water taps equipped with automatic sensing open/close device or automatic closing mechanism. Water taps installed at bath tub, any system, machinery and devices such as irrigation system, washing machines, water dispensers, etc. which serve for bathing/operational use, are excluded from this Scheme. 21

22 Testing Methodology and Standard Statutory Requirement Tested in accordance with and comply with the standard specified for the water taps by the Water Authority Upon the completion and compliance with the tests, the approval for the water taps shall also be obtained from the Water Authority. Scheme Requirement Reference to Australian/New Zealand Standard AS/NZS 3718: Testing items: Nominal flow rate Flow controller endurance (if installed in the water taps)

23 Testing Methodology and Standard To pass the performance requirements tabulated below Performance Property Nominal flow rate : Performance Requirements The max. difference between highest and lowest average flow rate should not exceed 2 litres/min. 23

24 Testing Methodology and Standard Performance Property Endurance of the flow controller (If incorporated) Performance Requirements Within ±1 litre/min of the nominal flow rate (About / on-off cycles) 24

25 Water Efficiency Grading The water efficiencies of the water taps are rated to different grades according to their nominal flow rates and type as shown below. Non-mixing Type Water Taps 25

26 Water Efficiency Grading Mixing Type Water Taps 26

27 Water Efficiency Label (Water Taps) Full and simplified versions 27

28 Water Efficiency Label A self-adhesive label To be affixed either to the plumbing fixtures and water-using appliances or the packing at a prominent location Simplified version label at the plumbing fixtures and water-using appliances (optional) Label shall follow the format specified by WSD The soft copy and colour code of the Label to be obtained from WSD 28

29 29 Certificate of Registration

30 30 Requirements on Testing Laboratory

31 Requirements on Testing Laboratory Either one of the following three requirements has to be met. The laboratory accredited by Hong Kong Accreditation Service (HKAS) under Hong Kong Laboratory Accreditation Scheme (HOKLAS) or a Mutual Recognition Agreement (MRA) scheme for carrying out the tests 31

32 Requirements on Testing Laboratory The manufacturer s or importer s in-house lab following ISO/IEC 17025; and The manufacturer or importer operates according to a recognized international quality standard (such as ISO 9001); and The in-house tests have been evaluated and certified by internationally recognized third party certification organizations. 32

33 Requirements on Testing Laboratory A HOKLAS or MRA scheme accredited laboratory for testing of water consuming appliances other than showers/water taps can demonstrate their capability of carrying out tests on showers/water taps. 33

34 34 Legal Provisions

35 Legal Provisions Trade Description Ordinance False information on label Copyright Ordinance Using label without authorization 35

36 36 Compliance Monitoring and Inspection

37 Compliance Monitoring and Inspection The scope of inspection including sample checking and testing for the following items: whether the label is affixed as required; whether the label is in correct format; whether the water efficiency grade rated based on the data submitted by the participant is in line with the grade rated from the results of random testing conducted by WSD; whether the data shown on the Label tally with the information listed on the registration certificate; and whether unregistered showers/water taps display unauthorized Labels 37

38 Compliance Monitoring and Inspection Participants to take remedial action and report the followup action taken if non-compliance is found on their registered products Participants to retest 3 samples if non-compliance with the grade shown on the label If non-compliance is confirmed and no or unsatisfactory remedial action is taken by the participant, WSD may order it to be de-registered from the scheme. Compliance monitoring and inspection will be conducted on random basis 38
