Any residential lawn watering outside of Saturday and Sunday mornings will be outlawed across the Metro Vancouver regional district on May 1, as officials brace to manage a historic low snowpack and prospects of a dry summer.
“With a low snowpack this year and every expectation of a hot and dry summer, it’s important that all residents make water conservation a priority,” said Delta mayor and the regional district’s chair George Harvie in a statement.
Starting May 1, residents will have only one morning per week to water their lawns; those residing at even-numbered addresses may automate watering between 5 a.m. and 7 a.m. and manually water between 6 a.m. and 9 a.m., on Saturdays; those at odd-numbered addresses may do the same but only on Sundays.
Trees, shrubs, and flowers can be watered with a sprinkler any day between 5 a.m. and 9 a.m., or any time by hand or using drip irrigation. And edible plants are exempt from the restrictions.
Commercial and industrial properties are limited to lawn watering on Mondays and Tuesdays.
Metro Vancouver officials say they had started to fill the region’s three reservoirs earlier than usual and so they are “on target to be full by mid-May,” with snowpack currently at 56 per cent of the historical average.
The snowpack station at Palisade Lake, north of Grouse Mountain, shows snow water equivalent at just under 465 mm, just outside the minimum range of about 480 mm and far from the historic range of about 900 mm.
However, weather forecasts for this spring and summer “anticipate prolonged periods” with little rain and above-average temperatures, prompting concern.
“Last year, we had to ban lawn watering mid-summer because use of our treated drinking water for outdoor use was too high,” said Malcolm Brodie, chair of Metro Vancouver's water committee.
“This year, we’re hoping to avoid escalating restrictions for as long as possible, but it really depends on you. Let your lawn go brown this summer, and save water for where it’s needed most: cooking, cleaning, and drinking."
Metro Vancouver now delivers drinking water to nearly 2.8 million residents using water from the Capilano, Seymour and Coquitlam reservoirs.
