Engineers and designers, take note: VPS’ water conservation and other benefits might be too much to ignore.
In the world of plumbing design, vacuum is the next frontier. Those with little knowledge of, or experience with, vacuum plumbing systems (VPS) may be like those who viewed the Gold Rush too risky. Most plumbing designers and engineers are comfortable with traditional DWV systems and see no reason to consider an alternative and certainly would not consider vacuum a pot of gold! However, as water shortages increase across the U.S., alternative approaches to traditional thinking must be considered.
