I believe this is the original pumping station that used to power the pumping of water from this reservoir to the reservoir on Clifton Down, next to the water tower. Next time I'm here I'll have to check out the rumour that there's a clear line of sight from here to the Downs, partly provided by a Bristol Water bungalow on Upper Belgrave Road. Mind you, even if it is a true story, the view's probably been blocked by some modern building or other by now...
