Each Vivos complex incorporates a deep underground water source capable of supplying a minimum of 20 gallons of water per minute.  This water is stored in large underground storage tanks until needed for use. 

On demand, water is pumped into the shelter, filtered through extensive ionization and filtration systems to remove all toxins, bacteria, chemicals, and contamination, and then stored in pressurized tanks for distribution throughout the facility.

There is ample water supply and storage for the predicted consumption by the Vivos inhabitants for each shelter.
