SANITARY CIRCUMSTANCES OF THE AREA
Water Supply
I am indebted to Dr. E. Windle Taylor, Director of Water
Examination, Metropolitan Water Board for the following report on
the water supplied to the Borough.
" The supply to the Lambeth area has been satisfactory both
in quantity and quality during the year 1957.
The water is all River Thames derived. It is stored in the
Board's reservoirs at Staines, Laleham and Walton and treated in
the Board's works at Hampton, Surbiton and Walton. The method of
purification is by storage, filtration and terminal chlorination
and contact tanks are in operation at Hampton and Walton to ensure
efficient disinfection of the water. The contact tank at the
Surbiton works has not yet been completed.
Samples are collected on five days in every week and more
frequently if required, from each stage of the purification process
and in the distribution system. Tests include physical, chemical
and micro-biological examination of the water.
All new and repaired mains are chlorinated before being
restored to service and samples of water from them are tested
bacteriologically to ensure that its quality is up to that normally
supplied.
The water supplied to the Borough of Lambeth is not plumbosolvent.

During the year 1882 samples of the water supplied to the
Borough of Lambeth were taken for chemical examination and 3438
for bacteriological examination.
The average results were as follows:-
