The life of a waterworks employee in the 1800-1900s wasn't a glamorous one. During the Wintertime when there was plenty water in the river, water was pumped to the high level reservoirs by two turbines located in a turbine house by the river's edge. The turbine house was a cold and damp place to work in the middle of Winter.
In the Summertime, when there wasn't enough water in the river to drive the two turbines, water was pumped to the reservoirs using a steam powered beam engine. The workers spent their Summers shovelling coal into the giant boilers in order to generate the steam to drive the beam engine. The hotter the Summer became , the more coal they had to shovel!!
