Abstract: A water delivery system (70) including a multiplicity of water dispensing systems (10), each including a water storage reservoir (12), a feed line (14), and a faucet (16), and a mobile, re-supply truck (30). Truck (30) includes a water tank (32), a water pump (34), and an ozone generator (36). Water dispensing systems (10) are installed at remote, on-site locations, such as for example residential homes and offices, and re-supply truck (30) services the dispensing systems (10) by delivering water from a water source (72) to each system. Each dispensing system (10), including its storage reservoir (12) is a closed, high pressure system, preferably at approximately 15 psi, so that power necessary to delivery water, on demand, from a storage tank (12) to a faucet (16) is provided by the system pressure.
