SECTION C.
SANITARY AND ENVIRONMENTAL CIRCUMSTANCES.
Water Supply.
I am indebted to the Director of Water Examination of the
Metropolitan Water Board, for the following statement and for
the details of analysis of water supplies which are set out in
Appendix 6.
"The supply to the district of Orpington is derived from
seven well stations, namely, Orpington, North Orpington, Jewels
Wood, Sundridge, Eynsford, Shortlands and Bexley.
Bacteriological analyses of these wells are made at least five
times a week and satisfactory results have been obtained throughout
the year. Chemical analyses of the wells supplies are also
made at regular intervals.
All supplies are treated with chlorine on the works, but any
excess remaining after a period of contact is removed completely
or reduced to an amount that will not be perceptible to the
consumers.
All new and repaired mains are disinfected with chlorine
before being restored to supply and samples of water from them
are analysed to establish that the water is up to the standard of
quality normally supplied.
None of the supplies is plumbo-solvent and we have no
information with regard to the proportion of the total number
of dwelling houses and population in Orpington which are
supplied from the above mentioned sources. All the houses are,
however, supplied directly and not by means of standpipes.
There are certain residential areas within the district that
are without main piped water supply, no less than 180 houses
being dependent upon underground tank or well supply.
During the year 33 houses previously devoid of main supply
were connected to water mains."
The following information has been supplied by the Clerk of
the Metropolitan Water Board :—
"The supply to the Orpington district during the year 1950
was satisfactory as regards quantity.
There have been no extensions of trunk mains in the
Council's area during 1950 and no new source of public water
supply has been instituted.
Lengths of service mains have been laid in various areas of
the Orpington district."
