Similar to the underground alternative, under deck water tanks are a cost effective way to install a full-size water tank on your property while saving valuable surface area. Under deck water tanks are ideal if there is little room for a larger tank and you want your rainwater storage to be out of view. By being positioned under deck, you don’t have to be concerned with the force of rain, wind or organisms that that can impact on the structure of the tank. Tucked away under the deck of your home, your tank won’t affect the look of your property – You may forget it’s even there!
