SANITARY CIRCUMSTANCES OF THE AREA
Report of the Chief Public Health Inspector
1. WATER SUPPLY.
Dr. Windle Taylor, the Director of the Water Examination Department
of the Metropolitan Water Board, has kindly supplied the following information
regarding the water supply for the district:-
"1. (a) The supply was satisfactory both as to quality and
quantity throughout 1967.
(b) All new and repaired mains are disinfected with
chlorine, after a predetermined period of contact
the pipes are flushed out and refilled; samples
of water are then collected from these treated
mains; and the mains are returned to service only
after results are found to be satisfactory.
The quality control from these laboratories is
carried out by means of daily sampling from sources
of supply, from the treatment works or well
stations, from the distribution system, and through
to the consumer. Any sign of contamination or any
other abnormality is immediately investigated.
(c) (i) The Board has no record of the number of
structurally separate dwellings supplied in your
area, but the population supplied direct according
to the Registrar General's estimates at 30th June,
1967, was 56,022.
(ii) No houses were permanently supplied by standpipe.
(d) No fluoride was added, and where the fluoride
content is indicated in the analyses it represents
the naturally occurring fluoride in the water.
2. (a) The supply was mainly Lee-derived water via Lee
Bridge works, with some well water from time to
time from Chingford Mill and a little from Ferry
Lane and Waltham Abbey. Between May and
September some water was derived from the interim
supply from the new Coppermills works. There
were no changes to the general scheme of supply
in your area.
The number of sairples collected and the bacteriological
and chemical analyses of the supply from
the above sources after treatment are shown on
the attached sheets.
