A large storm overflow tank has been installed, thereby
preventing the discharge of untreated sewage into the river,
on the occasions of heavy rainfall.
There is vacant land available for still further increasing
the filtration area, and more settlement tanks could be provided,
if necessary. The process shows itself to be increasingly
satisfactory in comparison with other systems installed
elsewhere, whether on the score of efficiency of treatment or
economy in working. It has one marked superiority in the
production of a useful furtilizer as a bye-product. The filtered
effluent contains about 1-pt. per million of Albuminoid
Ammonia. It is clear, sparkling and free from odour, and
not liable to putrefraction on keeping either at the natural
temperature or in an incubator.
The works are in the centre of the Town and adjoin the
Canbury Promenade and Public Gardens.
Sulphate of Alumina for precipitation is now made at the
Sewage Works and the steam engines have been replaced by
electric motors.
