Secret Water Stash. Looking for a way to capture water that doesn’t involve conspicuous rain barrels? The Original Rainwater Pillow collects large amounts of precipitation but is easily tucked away in a crawlspace or beneath a porch. It’s made from a reinforced polymer alloy that the company claims is tear-resistant and tolerant of extreme temperatures. The product can be configured to store up to 200,000 gallons of water. A basic 1,000-gallon kit containing the pillow, filters, pump, hose, and fittings costs $2,500. Rainwater Collection Solutions, 770/853-9918, www.rainwaterpillow.com
