Reason: Company Year end Dinner
Why not talk shop, why not brainstorm, on the very last day of the year before we meet again for the daily grind on January 2nd, 2012. Christy will be doing the same thing, Thinking, and being paid handsomely for her efforts. Whereas we six, will be paid on our own dime.
I put it to the plumber in the crowd "What's the water pressure going into a house?" "Depends" he said "on where you live." "North Shore" "80 lbs."

Its one thing to ask a simple question like water pressure going into a house without realizing where OUR water comes from in the first place. "A TAP".... good guess, try again. "The north shore?" Partially right. There's a bit of geography involved here, like why is Stanley Park's Prospect Point still there, after an IceAge has flowed off from a continent to finally settle a small portion of itself into English Bay and Georgia Strait....
Why oh Why is Prospect Point still there, after the Ice Age? Why doesn't every harbour have a Prospect Point?
The year is 1889, the date is March 26: The data that follows was prepared by Researcher: Roy J.V. Pallant
Surveys for the tunnel were simplified by the fact that the
centre of each shaft was visible from the other. - Page 9
· Ground level at the south shaft in Stanley Park some
distance back from the foreshore was twenty-three feet
above sea-level and conditions for open excavation were
most favourable. For the first sixty-five feet, the shaft was
in clay hardpan, the balance of the 400 feet in sandstone.
The shaft was timbered to a depth of twenty-five feet, after
which a concrete lining was used. After excavation of the
shaft and after the tunnel was driven several hundred feet,
a pump to lift 200 gallons per minute was installed and a
weir built which in fact sufficed until the tunnel was
|Pearson Scott Foreman|
A plug of concrete, twelve feet thick, was placed at the bottom of the Caisson, to stop it from moving and sealing it to the bedrock. The miners then drilled a hole through the concrete, and another 400 feet down through the bedrock
With the site fixed by the point where underlying sandstone
was at the least depth below sea level sinking of the north
shaft presented problems. To begin with, several feet of
water at average tides covered the location. That
necessitated a caisson within which sinking would be done.
Driving the tunnel was quite as routine as an ordinary
mining tunnel, the only essential difference being that the
bore was located 400 feet below sea level. While miners
pegged away with drill and jackhammer, great ocean liners
and noisy tugs steamed back and forth through the
Narrows entrance of one of the world's busiest harbours.
Three shifts of eight hours were worked continuously and
every round of holes fired marked an advance of seven or
eight feet. Use of extra powder broke up the muck so that it
was easily handled by hand labour loading small cars and a
locomotive hauling them to the south shaft where the spoil
was raised. (Page 11)
From the earliest days of the development of Vancouver
and district water supply, the submerged mains, now
superseded, have been considered a rather precarious link.
Years ago the Vancouver City Council instructed the later
Col. T.H. Tracy, first city engineer, to report on the
feasibility of a tunnel. Proposals were even put forward for
a bridge to carry the supply mains. (Page 13 of 14)
Homeowner operated IPP suggestion? Why not hook up a micro water driven hydro generator to the incoming water line to every household? Why not have larger users of water eg. Hospitals and Rec Centres, use the incoming pressure of water to supplement their electricity needs?
