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
1954:-
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 at the Hornsey works in July, 1954
(b) River Thames water stored in Walton Reservoir and treated at the
Board's filtration works at Walton,
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-solvent.
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.
Drainage and Sewerage
Separate systems of soil and surface water drainage continue to operate
in the Borough.
Co-operation with the Borough Engineer's department enables complaints
relating to stoppages to be dealt with expeditiously.
Some success has been achieved in dealing with pollution in the Moselle
and Lesser Moselle but investigations with regard to the Stonebridge brook
will have to be intensified.
