The plate in brief

Not all water needs to be drinking water. Drinking water comes from the safe mains supply and stays on its own pipes. Greywater from showers goes through screening, a membrane, and disinfection into a non-potable tank, then flushes toilets and waters the garden. Rain from the solar canopy and condensate from the air-conditioning coils pass a first-flush filter and disinfection, and then go to landscaping. Blackwater from toilets goes to a district treatment plant, as a separate sanitation stream.

Each city has its own extra water to catch: winter rain in Jerusalem, summer condensate in Haifa, storage for the dry season in Hebron. The rules don’t bend: separate pipes, multiple barriers, continuous monitoring.
