Watering restrictions begin for the Metro Vancouver region on May 1. The restrictions, which are set to be in place until Oct. 15, come into force after the area got its first blast of summer-like weather over the weekend. According to Metro Vancouver, water use increases 50 per cent during the summer months, likely due to lawn watering. Starting this week, people whose addresses are even numbers are permitted to water their lawns on Saturday mornings, while residents at odd-numbered addresses can water on Sunday mornings.
