An air cycle environmental control system for high pressure water separation omits a condenser heat exchanger and includes a reheater capable of placing compressed air in a heat exchange process to condense water vapor. A first turbine is in direct flow communication with the reheater, while the first turbine is capable of condensing water vapor from the compressed air. A water extractor is in flow communication with the first turbine and the reheater, while a second turbine is downstream of the reheater. The second turbine is capable of cooling a reheated, dehumidified air from the reheater to produce a conditioned air for supply to an enclosure. A method of water separation from a high pressure water vapor bearing air omits a step of condensing water vapor in a condenser heat exchanger and includes the steps of cooling a compressed air in a reheater heat exchanger such that the compressed air becomes a cold air. Water vapor is then condensed from the cold air to become a dehumidified air. Thereafter, a step of absorbing a heat of sensible cooling and condensation in the reheater occurs. Finally, a reheated air from the reheater undergoes expansion by a second turbine for eventual supply to the enclosure.
