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 (i) quality, and
(i.ii) quantity throughout 1968.
(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, 1968, was 56,350.
(ii) No houses were permanently supplied by standpipe.
(d) No artificial 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 derived from the following works and
pumping stations:- Lee Bridge works with some well water
from time to time from Chingford Mill and a little from
Ferry Lane works and Waltham Abbey well. Between May and
September some water was derived from the interim supply
from Coppermills Works.
No new sources of supply were instituted and there were
no changes to the general scheme of supply in your area.
The number of samples collected and the bacteriological
and chemical analyses of the supply from the above sources
after treatment are shown on the attached sheets.
