Total Quantity Manufactured since Installation of Plant.
Monetary Advantage to Borough.
Since the plant has been installed, a period now reaching five years,
140,000 gallons have been manufactured at a cost for electricity and
materials of under £271. The great monetary advantage to the Borough
since the installation of the Electrolytic Plant need not be referred to in
detail, as the fact has been the subject of reports again and again.
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 Asylums and of tha
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 expenses on bottles alone.
