REPORT.
Unfortunately there is no improvement to be noted either in the quality of the Kurnool water
or in the management of the water-works. At the time of taking the samples the water was not flowing
in the canal and that might contribute to the poor quality of the water. What can we say however to
settling tanks which bring about a ten-fold multiplication of the fœtal germs in a water. We know from
past results that these tanks are capable of bringing about marked improvement of the water. This
fact eliminates the question of faulty construction and almost certainly points to rank bad management.
of the tanks.
As this probability was pointed out in last quarter's report it is time that some vigorous action were
taken to prove or disprove it. This quarter the cleansing action of the pipes is not marked, At some
points there are reductions in the number of fœtal germs present but throughout the number of species
is large and objectionable.
Chemically the water is quite good, the small amount of organic matter present being of vegetable
origin.
