In Rosemount, city officials have strict advice about saving water: "DON'T overwater your lawn" and "DO let your lawn go dormant under drought conditions."
But the city itself last year installed a splash pad in one of its parks that spit out 5 million gallons in its first summer — and expects that figure to rise this year.
Safer, cheaper, more active and engaging than wading pools, splash pads are being touted as the nation's hottest new parks amenity. And they are proliferating here.
Woodbury and Burnsville added new ones this summer, as did Minneapolis. Maple Grove's is coming soon, and Columbia Heights is building one slated for 2016.
Minnetrista last week approved a plan that includes one. Hugo takes up the question in September, and Savage is eyeing one too.
But splash pads run through torrents of water at a time when hydrologists warn that we're depleting the clean, pure aquifers far beneath the soil.
Thomas Schaffer, president of locally based USAquatics, which has done $800 million worth of aquatics projects in more than 30 states, is worried.
"We probably do 80 percent of municipal pools in Minnesota," he said, "but we get less than 10 percent of the splash pad contracts, because 9 of 10 are running off the potable water system and it all goes into sewers.
