PART III
SANITARY CIRCUMSTANCES OF THE AREA
Water Supply
I am indebted to the Director of Water Examination of the
Metropolitan Water Board for the following report upon water
supplied to the borough during 1955.
"The supply to the Tottenham area has been satisfactory both
in quantity and quality during the year 1955. Details of the
analytical results of the water passing into supply are given in
the tables.
The area is supplied from two sources:-
(a) Water from the New River and treated at the Board's
filtration works at Hornsey and Stoke Newington. A
contact tank was brought into operation in July, 1954,
and the construction of a similar tank at Stoke
Newington is in an advanced stage.
(b) River Thames water stored in Walton reservoir and
treated at the Board's filtration works at Walton. A
contact tank was brought into operation in April 1953.
Samples are collected on five days in every week, or more
often if required, at each stage of the purification process and
tests include physical, chemical and microbiological examination.
The water supplied to this area is not plumbo-so1vent.
All new and repaired mains are chlorinated before being
restored to use and samples of water from them are tested bacteriologically
to ensure that its quality is up to that normally
supplied".
