Water supply
The bulk of the water supply in Wandsworth, as in other Inner
London Boroughs, is obtained from the mains of the Metropolitan
Water Board who are responsible for its purity, Water supplies
from this and other sources proved satisfactory both in quality
and quantity throughout the year,
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
the analytical results are found to be satisfactory,
The quality control from the Metropolitan Water Board's
laboratories is carried out by means of daily sampling from the
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,
All dwellings in the borough, numbering approximately
127,000 and catering for a resident population of 302,258, were
supplied from the mains of the Metropolitan Water Board, No
houses were permanently supplied by standpipe,
