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 1958.
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 Surbition works has not yet
been commenced.
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 services 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
plumbo-solvent. "
During the year samples of water supplied by the Metropolitan
Water Board to the Borough of Lambeth were taken for chemical and
bacteriological examination.
The average results were as follows
