Some of the city's 11 water and spray parks were under operating under restrictions because of drought conditions, unless they were equipped with the activation switches.
"In the old days we would turn them on all day. We couldn't control the flow of water at all of those parks," said Sean Healy, Supervisor of Aquatic Services for the Vancouver Park Board.
"Now with the hand activator, the user can push the button and water will only come out 10 am to 8 pm."
The process of converting the remaining parks began in July.
