Where does BW get its water from?

A borehole, that's where. At least, that's the case at Tyrley, on the Shroppie, as the latest Waterscape advice says:

Friday 23 May 2008 until further notice

The water point at Tyrley is currently not available.

The water supply at Tyrley is supplied from a borehole in a nearby field. The water is pumped and treated before it is supplied to the waterpoint. Unfortunately the pump and filter have failed and BW are currently investigating the most efficient, cost effective and sustainable solution to this problem.

The nearest alternatives to the North are Market Drayton and to the South, Norbury Junction.

British Waterways apologise for any inconvenience this may cause.

And I thought all water coming out of taps just came from the mains, all connected together like the electricity mains.
