II
Reynolds, Assoc. M. Inst. C.E., the Surveyor to the Council,
from plans made by him.
The method of treatment is as follows:—
The Sewage, which enters the Works by gravitation, is first
passed through a revolving screen, after which a solution of
Buxton Lime, equal to 4 grains per gallon, is added, and the
whole is thoroughly mixed. It then receives aluminoferric to
the extent of one grain per gallon, and is again well mixed by
passing through a salmon ladder, and in this condition flows into
settling tanks, of which there are three, each having a capacity
of 70 000 gallons. A fourth tank has been added, and is practically
complete. These tanks are divided by concrete walls, on
which is an open channel, divided by sluice doors, so that either
one, two, three or four tanks can be worked at a time and alternately
as required. The overflow from the tanks first passes
through coke screens into an open channel, then on to first contact
Bacteria Beds and through the filter or second Bacteria Beds into
an effluent chamber, and thence into the brook referred to above.
EARTH CLOSETS.
Four in the District, on isolated premises. The earth closets
at Hales's, Sydney Road, have been removed.
PUBLIC URINALS.
All these in the District have been reconstructed,
SEWERAGE.
The Roads in the District have separate drains for storm
water, most of the houses having the dual system of drainage.
Sewers have been laid in Myddleton Park, Balfour Grove,
portions of Holly Park Road, and surface-water sewer in Pembroke
Road, and an additional 18-inch outfall sewer from the
Sewage Works to Cromwell Road.
VENTILATION OF SEWERS.
The system of shaft ventilators is being extended to the
whole of the District.
REMOVAL AND DISPOSAL OF HOUSE REFUSE.
This is undertaken by the Council, through the Surveyor's
Department, the collections being regularly carried out by
means of covered improved dust carts. Iron dustbins are
required in place of the unsanitary brick and wooden receptacles,
which in many cases were attached to the houses. The refuse is
chiefly taken on to the Sewage Farm.
