The Public Health Department is not only furnished with the
disinfectant and the various institutions of the Council (the public baths,
etc.), but the institutions of the Managers of the Sick Asylum and of the
Board of Guardians (within and without the Borough) are supplied with
an unlimited quantity free.
For the Fluid supplied to the Works Department a charge of 1d.
per gallon is made ; the Public Health Department is credited with this
amount although no actual monetary transaction takes place.
As applicants now usually bring their own receptacles to the depots,
there is also a very appreciable saving in the expense on bottles alone.
From October, 1915, for Electrolytic Disinfectant supplied to manufacturers
and trading concerns, a charge of 8d. per gallon is to be made
through the Electricity Department, the Electricity Undertaking being
allowed an amount of 10 per cent. for establishment charges.
* See "Comments on Adverse Criticism," Annual Report, 1911.
† On page 92 it will be seen that the fluid is made of greater strength and afterwards
broken down to half strength for distribution, more electrical current being used.
