(i) Water Supply,
The district is supplied with water by the Metropolitan
Water Board, and during the year a good aNd
constant supply has been provided.
I am informed by the Clerk of the Metropolitan
Water Board that "No new sources of water supply
have been introduced in connection with the Borough
of Bexley during the year 1937. Approximately 9,390
yards of water mains were laid in the Borough during
the year."
"The wells from which the supply has been derived
have all provided excellent results during the year, and
all samples have yielded only three typical bact. coli in
the year, which is proof of the highest purity and reliability.
There has been 110 evidence of contamination
in any of the wells which furnished the supply and no
treatment has been installed."
Examination of samples of water from piped supplies
to houses in the district have been made with the following
results:—
Bacteriological.

The only remaining houses in the Borough where the
water is not led by a pipe to a tap inside were the subject
of demolition orders during the year.
