29 Water Consumption Statistics Report October 21 General 29 GVWD STATISTICS BOOK NOTES The Greater Vancouver Water District (the GVWD or the District ) is one of the four separate entities that operates under the name Metro Vancouver and is responsible for supplying water to its member municipalities. 1. This issue of the statistics book supersedes all previous issues. 2. The municipal peak day flows are determined from the day of the GVWD s peak water withdrawals from the sources. Individual municipal peak day consumption may not coincide. 3. Prior to 1987 peak week demand is calculated for the week containing the peak day. Starting 1987 and for subsequent years, peak week is the true annual peak week. 4. Abbreviations used in this book: ML/d millions of litres per day Lpcd litres per capita per day 5. The Village of Anmore joined the GVWD in 1999. However, statistical data regarding water consumption are currently not available. The Village of Anmore s consumption is included with the City of Port Moody s consumption. 6. The Village of Belcarra joined the GVWD in December 28. However, statistical data regarding water consumption are currently not available. The Village of Belcarra s consumption is included with the District of North Vancouver s consumption. 7. As of 22, system flow represents flow drawn from the sources. Previously, system flow represented flow delivered by the transmission network. Municipalities with Additional Water Supply Sources 1. In addition to water supplied by the GVWD the following municipalities use their own sources: Corporation of Delta (wells) Township of Langley (wells) District of Maple Ridge (wells) City of Surrey (wells) District of West Vancouver (Eagle Lake) 3

29 Water Consumption Statistics Report October 21 The percentage of the municipal water use from the above sources may vary. 2. The City of White Rock fully depends on its own water supply wells and is not a GVWD member. Population 1. Population figures were drawn from the following sources: 1961 1986: 1987 1991: 1992 1995: 1996 29: Tables titled Municipal Statistics published by the Department of Municipal Affairs of the Province of BC. Statistics Canada. BC Ministry of Government Services, Planning and Statistics Division. Population Section, BC Stats, Government of British Columbia Some population figure discrepancies may be apparent upon comparison to some of the previous GVWD statistics books. These figures may have relied on different sources of information. 2. Assumed percentage of Township of Langley s population supplied with GVWD water: Year Percentage Year Percentage prior to 1989 % 1999 34% 1989 2% 2* 33% 199 4% 21* 36% 1991 23% 22* 29% 1992 28% 23* 3% 1993 23% 24* 3% 1994 25% 25* 3% 1995 32% 26* 33% 1996 23% 27* 34% 1997 2% 28* 33% 1998 26% 29* 36% * Based on figures supplied by the Township of Langley. 4

29 Water Consumption Statistics Report October 21 Per Capita Consumption 1. Per capita figures include non-residential water consumption. 2. System as a Whole: Only the percentage of the Township of Langley population assumed to be serviced by GVWD water (see Population notes) was included in the system population used to compute system per capita consumption. 3. University Endowment Lands (UEL): UEL per capita flows include all UEL and UBC flows. However population denomination may not include all UBC transient population. 4. West Vancouver, Maple Ridge, Township of Langley, Delta, and Surrey: Although the above members have their own secondary supply sources (see "Municipalities with Additional Water Supply Sources"), for the calculation of per capita consumption at the municipal level, the total municipal population has been used. 5. Anmore and Port Moody: While Anmore s consumption of GVWD water is included in Port Moody s consumption, that portion of Anmore s population so supplied is not added to Port Moody s population. Factors That Affected Water Consumption in Most Recent Years 1992: Region wide summer lawn sprinkling ban for 1 weeks. 1993 22 * : June 1 to September 3 region wide restrictions limiting lawn sprinkling to restricted hours in the morning and evening two days per week. 23: 24 9: Region wide restrictions limiting lawn sprinkling to two days per week from June 1 were increased to one day per week on August 5 th. On August 22 nd a region wide sprinkling ban was imposed due to the unprecedented low storage level and unusually warm and dry weather. June 1 to September 3 region wide restrictions limiting lawn sprinkling to restricted hours in the morning and evening two days per week. *In addition to regional restrictions, a total sprinkling ban was introduced during the summer of 1997 for approximately 1 weeks in the Corporation of Delta, City of Surrey, City of Langley and Township of Langley. This ban was implemented due to the Port Mann Main Fraser river crossing failure. 5
