Stumbled across this little water works whilst at work, not the biggest site but very interesting.
This little pump house was constructed in 1905, it had a single cylinder diesel engine pumping water up into the old water tower on Tower Meadow. The tower was demolished in 1967.
What is really interesting is the name Glemsford was chiseled out of the window stone as a anti invasion measure in 1940, which is clearly seen in my photograph.

Thanks for looking.
