We installed this water recovery system a few years ago and we have saved 18%+ on our water bill every year since! It works by pulling your clean, non-potable water into the 100 gallon heavy plastic water container from you dry clean machine and then sends it to your washer as required. Pay back can be very short, as it was for us. We first saw one of these at a TIDE plant, and figured they researched it, so must be good - and it has been! We're retiring, so you can get the benefit!
