5 212 GVWD STATISTICS BOOK NOTES 212 Water Consumption Statistics Report December 213 General 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. is the day of annual maximum withdrawal from the sources. The municipal peak day flows in this report are determined from flows on. Actual municipal peak day consumption may differ slightly. 3. Prior to, peak week demand was calculated for the week containing the peak day. Starting and for subsequent years, peak week is the true annual peak week and may not include the. 4. As of 22, system flow represents flow drawn from the sources. Previously, system flow represented flow delivered by the transmission network. 5. Abbreviations used in this book: ML/d millions of litres per day Lpcd litres per capita per day 6. The Village of Anmore joined the GVWD in. However, Anmore s water consumption is supplied by the City of Port Moody. Complete statistical data regarding Anmore s consumption are currently unavailable. Consequently, the Village of Anmore s consumption is included with the City of Port Moody s consumption. 7. The Village of Belcarra joined the GVWD in December 28. Belcarra s water consumption is supplied by the District of North Vancouver and statistical data regarding water consumption have not been obtained. Consequently, the Village of Belcarra s consumption is included with the District of North Vancouver s consumption. 8. The Tsawwassen First Nation (TFN) joined the GVWD in April 29. A metered connection to TFN was commissioned in November 211. However, the connection registers only very minimal consumption. The bulk of TFN s consumption is provided by the Corporation of Delta and is included with Delta s consumption. Municipalities with Additional Water Supply Sources 1. In addition to water supplied by the GVWD the following municipalities use their own sources: 3

6 212 Water Consumption Statistics Report December 213 Corporation of Delta (wells) Township of Langley (wells) District of Maple Ridge (wells) City of Surrey (wells) District of West Vancouver (Eagle Lake) 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: : : : : Tables titled "Municipal Statistics" published by the Department of Municipal Affairs of the Province of BC. Statistics Canada. Population Section, BC Stats, Government of British Columbia Regional Planning, Planning, Policy and Environment Department, Metro Vancouver Different sources of population statistics have different historical values for population estimates. Consequently, this report may have different historical population figures than previous editions of this report. 2. Assumed annual percentage of Township of Langley s population supplied with GVWD water which is used to compute per capita consumption: Year Percentage Year Percentage Year Percentage prior to % 2% 26* 33% 2% % 27* 34% 199 4% 34% 28* 33% 23% 2* 33% 29* 36% % 21* 36% 21* 36% 23% 22* 29% 211* 36% % 23* 3% 212* 36% 32% 24* 3% % 25* 3% * Based on figures supplied by the Township of Langley. 4

7 212 Water Consumption Statistics Report December 213 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 on Page 4) 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. Delta, Maple Ridge, Surrey, and West Vancouver: Although the above members have their own secondary supply sources (see "Municipalities with Additional Water Supply Sources" notes on Pages 3 and 4), for the calculation of per capita consumption at the municipal level, the total municipal population was used. 5. Port Moody, District of North Vancouver, and Delta: While Anmore s, Belcarra s, and Tsawwassen First Nation s consumption of GVWD water is included in Port Moody s, District of North Vancouver s, and Delta s consumption values respectively, those portions of population so supplied are not added to the respective municipal population figures (see General notes on Page 3). Factors That Affected Water Consumption in Most Recent Years 1992: Region-wide summer lawn sprinkling ban for 1 weeks. -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: 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. 211: June 1 to September 3 region-wide restrictions. The majority of municipalities implemented new lawn sprinkling hours in 211, limiting lawn sprinkling to restricted hours in the morning three days per week. A minority of municipalities implemented the same sprinkling hours as were in place for the 24 to 21 period. 5

8 212 Water Consumption Statistics Report December : June 1 to September 3 region-wide restrictions limiting lawn sprinkling to restricted hours in the morning three days per week. *In addition to regional restrictions, a total sprinkling ban was introduced during summer 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 failure of the Port Mann Main Fraser River Crossing during the Spring freshet. 6
