Water supply
I am indebted to the Director of Water Examination of the
Metropolitan Water Baord for the information on which the following
report on Lewisham's water supply is based.
The water supply is mostly Thames-derived filtered water but there
is also admixture from the Board's wells at Bexley, Darenth, Deptford,
Shortlands and Wilmington.
All the well water is chlorinated and contact tanks are provided.
Finally, any residual chlorine is completely removed or reduced to a
level that would not be noticeable to consumers before the water leaves
the works.
Bacteriological analyses are made at least five times a week and in
the case of the river-derived supplies the water is analysed at all stages
of purification. All new and repaired mains are chlorinated before
being put to use and samples are collected for analysis to establish that
the quality of the water is up to the standard normally supplied.
None of the supplies is plumbo-solvent.
Tables 18 and 19 show the average results of the chemical and
bacteriological analyses of the various supplies as forwarded by the
Metropolitan Water Board:—
