They have achieved what seemed impossible! We first encountered Advanced Water Systems at a community event. I was skeptical due to the severity of our water problem. A number of companies came and tried to make our water drinkable and never succeeded. Advanced Water Systems said that they could help. After the meeting, we decided to give them a try. His team came in, tested the water, made recommendations and installed the water production system. We are now drinking our water!!! I thought it was too good to be true and it still seems implausible to be drinking out of our water tap. They have achieved what seemed impossible! I cannot say enough about these guys and their abilities. Thank you again Roger, Rich, and the entire team at Advanced Water Systems.
