Abstract
A system for the delivery and storage of bulk quantities of high quality water. The system includes a tank truck having air filters to preclude the entry of noxious materials into the bulk water hauling tanks. A delivery valve and a receiving valve are provided for the substantially air-free transfer of water from the bulk water hauling tank to a storage tank from which water can be supplied to the user. Water storage systems are provided including check valves to protect the quality of the water and the amount of residual water remaining in the storage tank. A pressurized water storage system is provided using a harmless gas and a floating check valve to contain the gas as water is drained from the storage system.
