the Companies, is about 1,350,000,000 gallons per day. It will
thus be seen that, when 300,000,000 gallons are taken, there will
be left to flow down into the tidal portion of the river an average
daily quantity of not less than 1,000,000,000; and we think that
regulations could be framed under which the quantity we suggest
could be taken, not only without reducing the flow of the river
on the rare occasions of exceptional drought to the present
minimum, but in such a way as to secure that the volume of
water left in the river at these times should be substantially
greater than it is under existing conditions.
To our minds, one great advantage of such a scheme of
storage reservoirs is that it can be carried out progressively to
meet the increasing demands for water; and should the population
not grow so rapidly as we have thought it right to
contemplate, the extensions may be from time to time deferred
as successive decennial enumerations reveal that the ratio of
increase is remaining stationary or even falling. From the
sources and by the methods we have mentioned, a daily supply
of 424,000,000 gallons can, in our opinion, be obtained. This is
a sufficient quantity to supply 35 gallons per head to a population
of 12,000,000 persons, which is about three-quarters of a
a million in excess of what the total population of Greater
London, together with the outlying parts of Water London,
will have become in 1931 even if the ratio of increase in the last
decennial period from 1881 to 1931 is fully maintained. We are
further of opinion that a large supply of water might be obtained
from the chalk area east of the Kent Companies' district in the
basis of the Medway, and in the district further east, without
any risk whatever of damage to that area.
