I consider that the success of informal action is a good
measure of the standing of the department with owners, estate
agents, traders and others. For the early part of the report on
water supply, I am indebted to the Metropolitan Water Board and
South Essex Waterworks Company, and the Borough Engineer
for the reports on Main Drainage and Sewerage, Refuse Collection
and Disposal end Street Cleansing.
Water Supply
The water supply of the Borough of Redbridge is provided
by two statutory undertakers, namely the Metropolitan
Water Board and the South Essex Waterworks Company and has
been of satisfactory quality and sufficient quantity during the
period under review.
The principal source of supply of the former is from Lee
and Thames - derived water from lee Bridge Works, repumped
at Woodford where it was supplemented between May and
September by the interim output fro n the new Coppermills Works.
In addition, parts of the borough receive well water from
Wanstead Pumping Station. 1,125' samples were submitted to
chemical and/or bacteriological examination. No fluoride was
added, although there was a natural fluoride content of 0.35
milligrammes per litre in the River Lee derived water. The
supply being hard in character is not liable to be plumbo-solvent.
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 the laboratories is carried out by
means of daily sampling from sources of supply, through the
treatment works or well stations, from the distribution system
and through to the consumer. Any sign of contamination or
other abnormality is Immediately investigated.
No houses were permanently supplied by standpipe, during
1967.
The South Essex Waterworks Company on the other hand
derives its supply mainly from the River Stour and from deep
wells at Mill Road, Grove Road and Roding Lane. The General
Manager and Chief Engineer of the South Essex Waterworks
Company states that during 1967 over 10,000 chemical and
bacteriological examinations of raw water, water during treatment
and water going into supply were, made at the Company s
Langham Laboratory and all water going Into supply was
reported as wholesome.
