Some of the films were very critical, rightly so, of several aspects of the water supply.
The film 'The Profits Pump' examined the tricks of the trade used by some water companies to boost returns to shareholders at customers' expense.
Others examined the rich architectural and engineering heritage of water supply, waste treatment and water towers. Historian Richard Gill of the Victorian Society took viewers around Luton's magnificent but derelict Bailey Hill Water Tower which has since been converted into a luxurious home.
The films are archived in Real Player format, they're very lo-fi but watchable. BWTAS suggests watching them as they're very good but also, if they get enough traffic, the BBC will be encouraged to maintain access to them.
