With regard to the West Middlesex Company,
Prof. Frankland remarks—" Except in the months
of January, February, and March, when intense
cold prevailed, this Company delivered water of a
high degree of organic purity, rivalling that of the
deep-well water of the Kent Company. In November,
the number of microbes was only 12 per c.c., when
the raw water at the intake contained 29,260."
The storage capacity of this Company is 6.3
days' supply.
Of the Grand Junction he says—"The small
amount of storage possessed by this Company
renders it difficult for them at all times to maintain
efficient bacterial filtration, and six out of the
thirteen samples collected at Hampton Works
during the year contained an excess of microbes or
their spores—over 100 per c.c.; whilst four out of
the twenty-five samples collected at the New Works
also contained an abnormal number of microbes.
Most of the abnormal results occurred when the
raw river water was bacterially in a bad condition,
and during severe frost." The storage capacity of
this Company is 3.5 days' supply.
The comparison instituted in Table 33 shows
that the supply given by the West Middlesex
Company was superior to that given by the Grand
Junction Company, except in the first three months
of the year, when the frost deranged filtration.
