Abstract: A water supply insurance method for providing an emergency water supply in a severe water shortage includes the steps of securing water rights to a water source and initiating discussion with a water-using client for issuing of a water supply insurance policy, including information pertaining to expected water needs, term of insurance and cost of water supplied. An insurance rate for the water-using client is calculated based the information and premiums are collected. When the normal water supply is significantly interrupted, emergency water is provided in the amount specified in the water supply insurance policy until the crisis is over, and then collection of premium payments from the water-using client is resumed to ensure future supply of emergency water so long as the water supply insurance policy remains in force.

Abstract: A portable water filtration device includes a liquid-tight filter container and a filtration device mounted in the liquid-tight container. The filtration device includes an inlet opening extending through one of the walls and a first filtration device in liquid transfer connection with the inlet opening operative to receive and filter liquid flowing therethrough. A second filtration device is operative to receive liquid from the first filtration device and further filter the liquid flowing therethrough. The first and second filtration devices are selected from the group including ultraviolet, activated carbon and reverse osmosis filters, and an outlet opening extending through one of the walls then receives the treated water and releases the water from the filtration device. Finally, the liquid-tight filter container is operative to prevent liquid from entering the interior volume thereof thereby preventing contamination of the filtration device from accidental incursion of contaminants.
