Metro Vancouver says hot and dry weather and low rainfall since late April this year underscores the need to conserve water across the region.
The regional government says reservoir levels remain normal for the season, but water consumption is trending higher than the same time last year.
It says water consumption peaked on July 5th with 1.56 billion litres used, even though it wasn't a day designated for watering lawns.
It's asking residents to curtail their outdoor water use and only water lawns once a week, or stop all together until rainy weather returns.
