WATER SUPPLY:
The Borough has a dual source of water supply:—
1. The Metropolitan Water Board supplying an area
bounded on the West by the London Midland and
Scottish Railway, on the North by a line along the
Mutton Brook to Bridge Lane and on the East
by the London North Eastern Railway. The remaining
Northern portion of the Borough is
supplied by the Colne Valley Water Company.
The Metropolitan Water Board supplies selected
Thames water which has been subjected to purification
by storage in which time it is freed of the
bulk of organisms. it is filtered through rapid
and then slow filters, attaining a degree of purity
which compares favourably with the general
supplies in Great Britain, but as a further safeguard,
terminal chlorination is applied which ensures
a first class water in every respect. Samples
of waters and filter beds are examined bacteriologically,
chemically and for taste and other special
purposes on every working day.
2. The Colne Valley Water Company derives its
supply from deep wells sunk into the chalk and
before distribution to the consumers the water is
under the constant supervision of a chemical and
bacteriological staff which carries out examinations
in modern laboratories situated at the Works.
A high standard of purity is maintained.
