Letters to the Editor: Are our water networks competent?

A tidal turbine in the Orkneys: One letter writer believes harnessing tidal power here would be a great project for young engineers.

Since August 6, I turn on the tap each morning in trepidation, as I wait to see what colour the water coming from the tap will be that day. Today is the 43rd day and it looks like being one of the worst ones yet.

Teeth are washed using bottled water. Dishes are washed when the brown tap water fades to yellow for a while. With luck it may clear later in the day and a shower may be possible or some clothes may make it to the washing machine before the water goes brown again.
