The water war has started.

Cities throughout the tri-county area are competing for the Most Water Wiser title. Residents of 102 cities are invited to take the water pledge (it takes less than a minute) and let the challenge begin.

The prize? Bragging rights, of course, but also, residents of the winning city will be invited to the South Florida Living Green Fair, Nov. 14-15 for a chance to win an eco-friendly scooter.

So far, Aventura is leading the challenge, with Boca Raton and Cooper City in second and third place.

Why it’s worth taking the pledge: In one year, a person can save: 30,665 gallons of water and keep 75 water bottles out of landfills.

What city do you think is the most water-wiser? Are you doing anything to save water? We’d love to read your comments.
