SECTION C.
SANITARY AND ENVIRONMENTAL CIRCUMSTANCES
OF THE AREA.
WATER.
I am indebted to the Clerk, and the Director of Water
examination, of the Metropolitan Water Board, for the following
information on the supply of water to the Borough during the
year 1952:—
"No new source of public water supply has been instituted
in the Council's area during 1952, and there have been no
extensions of trunk mains, but lengths of service mains have
been laid within the Borough, largely in the Council's Hayes
Place Estate. The supply to the Bromley district during 1952
has been adequate at all times. The higher level of the area is
supplied from Shortlands Well and by Thames-derived filtered
water from Walton Works; the lower level is supplied from
West Wickham and Orpington Wells with additional Thamesderived
water during the summer months.
All the Thames-derived water is chlorinated before it leaves
the works. The well water is also chlorinated, but any residual
chlorine is completely removed before the water leaves the
works.
Bacteriological analyses of all supplies are made at least five
times a week, and in the case of the river-derived supply, the
water is tested bacteriologically at all stages of purification. All
new and repaired mains are disinfected with chlorine before
being restored to use and samples of water from them are tested
to establish that the quality of the water is up to the standard
normally supplied.
None of the supplies is plumfoo-solvent.
The closest watch is kept for any evidence of deterioration
in quality whether physical, chemical, bacteriological or
biological and immediate action is taken if the results of analyses
are not up to standard.
Appended are the average results of the chemical and
bacteriological analyses of the various supplies for 1952."
