and socket joints and/blocks. This might ensure the
breakage at the breaking joint provided, otherwise the
pipe might be damaged.
Mr. Henderson has arranged to examine the
different joints made by Messrs. Stewarts & Lloyds, which
they can construct so as to break at the required
points, he is also to enquire as to the welded joints
which he specifies for the rest of the pipes.
In the case of a broken pipe, Mr. Henderson has
carefully considered the matter, sets out his procedure
with spare parts, and skilled labour available, and
the experience he has of the site, I see no reason whey
he should not be able to reinstate a broken pipe
within a few weeks. In these circumstances, I am
informed the supply of water can be maintained from the
existing sources.
The pipe line is specified to be lined inside with
cement. In view that this is a temporary pipe, with
limited years of life, and seeing that the jointing
by welding of a large length of pipe would have a
serious effect upon the lining, I suggest the lining be
omitted, and the cost put into extra thickness of metal
in the pipe itself.
I understand that no action from the water itself
may be expected on the piping.
I need not enumerate points of detail in
construction of this pipe line, as they have been discussed with Mr. Henderson, noted and agreed.
There are no doubt points of practical difficulty
that will arise in constructing the work, but Mr.
Henderson's local knowledge should enable him to adjust
such points as they arise.
I am,
Gentlemen,
Your obedient servant, (Sgd) WILLIAM FAIRLEY.
