The theme of the United Nation’s 2017 World Water Day on March 22 is wastewater and also Why Waste Water?. P&G’s Pantene, a product for whom water is integral, has come up with a water conservation solution: a limited edition ShowerGlass bottle at supermarket locations in Los Angeles. With a call to action of “Flip the bottle to time your shower,” the Pantene Pro V bottles carry a five-minute hour glass timer strapped onto the bottle with a silicon band. The campaign from Pereira & O’Dell has received requests to bring the campaign to other parts of Southern California. The campaign also offers positive advice on water-saving tips. Various California government agencies estimate that limiting showers to five minutes could save 12.5 to 25 gallons per person per shower.
