Filtered water indifferent. Supply as
a whole continues to be bad, as a
result of mixing unfiltered with
filtered water. Chlorination of the
raw water is being practised at the
Red Hills end of the conduit. Its
beneficial effect. is not manifest at
the final service ends where the
supply is still often inferior to the
lake water in general qualities.
