As to physical properties, the Richmond well-water contains 27
parts per 100,000 of hardness, whilst the M.W.B. water contains 22.
During the year 1944, three samples were taken from the raw
water, and found on analysis to be bacteriologically satisfactory.
Chemical investigation, however, was regarded as unnecessary since
the tests for the previous ten years had given uniformly good results.
Despite these excellent qualities in the raw water, the whole of
the drinking-water for the Borough is chlorinated before going into
supply, a small residuum of chlorine being allowed to remain in
solution as an extra precaution. Of the water so treated, no fewer
than 37 samples were taken during the course of the year, and these
reached the highest standard of bacterial purity, being virtually sterile
in every instance.
The Richmond drinking-water is thus of unexceptionable quality,
and most suitable for the purpose of a public supply. It is moreover
available by piped delivery to every building in the Borough.
