e-book on Dorset water towers

Photographer Rich Meston has contacted BWTAS to tell us about his free e-Book 'Tower' a photographic study of what else, a local water tower. He writes:

This is a collection of sunrise shots from my office window, all of which feature the Water Tower at Tower Park in Poole, Dorset (in one way or another). There’s technical details for each of the shots, and a few hints and tips throughout. Let me know what you think.
Rich would like to enlist BWTAS brains trust for any information on one tower at Calluna Road, Poole.

Rich says: it's an interesting and very dominant structure on the horizon, and I lived in the area when it was built in the late 1980's. I had a bit of a search around, but couldn't find any information out and wondered if you knew of any other places to look. I'm primarily interested in the obvious details - when it was built, how tall, what capacity, what it's used for etc.
