SANITARY CIRCUMSTANCES OF THE AREA
Water Supply
I am indebted to the Medical Director of Water Examination of
the Metropolitan Water Board for the following report upon water
supplied to the borough during 1957
"The supply to the Tottenham area has been satisfactory both
in quantity and quality during the year 1957 Details of the
analytical results of the water passing into supply are given in
the following table
The Borough of Tottenham is supplied from two main sources:-
(a) Water from the New River consisting of a mixture of River
Lee water and well water, treated at the Board's filtration
works at Hornsey and Stoke Newington A contact
tank for the efficient treatment by chlorine was brought
into operation at Hornsey in July, 1954 and a similar
tank is now in operation at Stoke Newington.
(b) River Thames water stored in the Board's reservoir and
treated at the Board's filtration works in the Thames
Valley,
Samples are collected on five days in every week or more
often if required, at each stage of the purification process and
''
from the distribution system Tests include physical, chemical
and microbiological examination-
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.
The water supplied to this area is not plumbo-solvent ."
Drainage and Sewerage
Separate systems of soil and surface water sewerage continue
to operate throughout the Borough.
Reports of pollution in water courses are received from time
to time and investigations are carried out to ascertain the source.
Such investigations present a problem in a Borough of this character
where much of the drainage is very old. Domestic pollution
