What about an award winning, on-site system generating non-toxic cleaners and sanitizers from salt, water and 120V of electricity. Ancillary systems bring cleaners/sanitizers to point of use (i.e. dishwasher, ice machine); whole building water circuits dosed with tiny amounts of the sanitizer keep biofilms from forming in building water lines (keeping water safe); and there is an application to recycle & purify (harvest) captured rainwater into potable water for resident use.
