1. An environmental control system of a vehicle comprising:
a first inlet for receiving a first medium provided from a first source;
a second inlet for receiving a second medium provided from a second source, the second source being different from the first source;
an outlet for delivering a conditioned medium to a load;
a first compression device including a compressor configured to receive and compress the first medium and a turbine configured to receive and extract energy from the first medium, the compressor and the turbine being operably coupled by a shaft; and
a second compression device configured to receive and compress the second medium;
wherein the first medium at a location downstream from the turbine and the second medium are mixed together at a mixing point such that a mixture of the first medium and the second medium is the conditioned medium provided at the outlet; and
a water separator arranged upstream from the outlet and downstream from the mixing point relative to a flow of the conditioned medium.
