High service works is situated high upon the hill and recieves water from the Beam Engine(s) (would it pump that far up without a middle stage?)
The process looks to be similar to the Low Servive Works. Raw water recieived in the semi-circular Storage Reservoir (uncovered) gravitates to the 4 sand filters anfd then into the service reservoir and feeds high level parts of Derby.
