"multi-award winning water storage with unsurpassed functionality" 

Rainwater HOG is a multi-award-winning water storage tank that works like a water-filled building block.  HOGs can connect together and store water in any orientation.  Rainwater, grey water and emergency water are all best stored in the stackable Rainwater HOG tank. 
I'm delighted to boast of my rain water collection system, made possible with style by Water Hogs! This modular system combines form and function with eco-grooviness. It's a perfect solution for the environmentally conscious home-owner looking to do her fair share - and more - to conserve water.   Woodside CA homeowner, 2500 gallons stored with 50-gallon HOG tanks on house, shed & stables
