DOUG WEINSTEIN WANTED TO BUILD SOMETHING LIKE THIS, ONLY DEEPER, AS A TOURIST ATTRACTION, BUT I DON’T THINK HE EVER FOUND ANY BACKERS: Homeowner Builds $2 Million Scuba Diving Pool In His Backyard. “In addition to having a water slide, wading area, grotto and other amenities, the pool in Springville, Utah is 140ft/43m long, 60ft/18m wide and at certain points 26ft/8m deep. The US$2 million pool — which holds about 360,000 gallons/1.4 million liters of water — was built so the avid scuba-diving owner could practice his skills without having to travel.”
