Flatish Plastic Water Meter

Calgary leaks out an inventive water conservation campaign - Fill a Frisbee, Save a River.

From the Canadian Metro News:

Dogs love to chase it, hippies love to toss it and, now, everyone should use it as a water meter.

That’s about all a lawn needs every week to stay healthy,” said City of Calgary Water Services public program coordinator, Kate Murray, adding if a person takes their Frisbee, turns it upside down under their sprinkler, the amount of time it takes to fill up should be all a lawn needs to maintain its green sheen.
