From a detailed investigation of the past records
it appears that had there been no restrictions during 1930
the consumption of that year would have been 10*80 M.G.D.
or 3,940 million gallons per annum.
For the next 15 years we consider that a conserv
tive estimate of annual increase would be 100 M.G. so that
by the end of 1945 the consumption will be 5,440 M.G. or
14.90 M.G.D.
It must be borne in mind that steadily, though
possibly slowly, the standard of living is rising, and
although today the percentage of the population for which
water-borne sewage disposal is available is small, this
percentage must increase, and the general adoption of this
system would add 20 to 30 per cent. to the water consumption.
In Paragraph 7 we have given the total available
resources of the Island as 12'85 M.G.D., so that in some
seven years time it will be necessary to supplement the
local resources by Mainland water.

We observed that in the Peak District there were
a number of houses within the catchment area which, under
. normal conditions and unless completely sewered, would not
be considered satisfactory from a Vaterworks Engineer's
point of view. As all the water is filtered and chlorinated
there would appear to be no reason why further building under
suitable restrictive conditions should not be allowed,
