You may (or may not) be thoroughly excited to know that the Institute of
Plumbing ( http://www.plumbers.org.uk/ ) published in 1998 a book by
Charles Knevitt called "Well Washed and Watered", a history of plumbing
from 9000BC to the present.
BTW, I'm pretty sure that Charles Knevitt is the architecture correspondent
for The Times. :-/
