SECTION B
SANITARY CIRCUMSTANCES OF THE AREA
WATER SUPPLY
The domestic water supply in the Borough is taken from the Metropolitan
Water Board. Samples of the water are subjected to regular routine chemical
and bacteriological examination at the Board's laboratories and the results
of these examinations are made available to the local authority.
The water supply to the Borough has been satisfactory both in quality
and quantity during 1961.
The water supply to the area is a mixture of River Thames-derived and
River Lee-derived filtered water in varying and unpredictable proportions.
The water from these two sources is stored in the Board's reservoirs and
filtered and chlorinated on the Board's works before being pumped into supply.
Samples are collected at each stage of the purification process, as the water
is pumped into supply, and in the distribution system. A summary of the results
of the chemical and bacteriological analyses of the water passing into supply
from these two sources for the year 1961 is set out on page 14.
The waters are not plumbo-solvent.
Immediate action is taken in respect of any form of contamination revealed
by inspection or analysis. All new and repaired mains are disinfected with
chlorine and the water in them is checked as to its quality afterwards, before
the structures are restored to service.
All inhabited houses are supplied with a piped water supply direct to
them and no houses are permanently supplied by standpipe.
There have been no new sources of supply nor new important extensions
of trunk mains in this area during the period under consideration, and there
were no changes in the general scheme of supply. New mains were laid to the
extent of 1,193 yards.

Examination, Metropolitan Water Board, who supplied these facts and figures.
