It is essential because of the deteriorating condition
of the Works that nothing should be allowed to delay
the transfer of sewage to the Edmonton Works by 1963."
Fly Nuisance.
No complaints were received during the year as to the emergence of
flies from the waters of the Metropolitan Water Board Reservoirs and it
was evident, therefore, that the new treatment put into operation in
1957 could be regarded as most successful. This treatment consisted
of spraying with a chemical insecticide termed Dieldrin in the place
of spraying with a watery suspension of D.D.T. powder.
Public Cleansing
(a) Refuse Collection
As in previous years it is pleasing to report that a weekly
collection of refuse and salvage was maintained. Whilst this service
was carried out with clockwork regularity week after week it could only
be done at the expense of the street cleansing service, as street orderlies
were used to supplement the men employed for the purpose of refuse
collection when these latter were away siclc or on holiday. During
the year under review many men/days were lost to the street cleansing
service by this means, but refuse collection, quite properly, was
regarded as the paramount public health service.
The total weight of refuse delivered to the Works was 11,705 tons
as compared with 11,989 tons in the previous year. The Registrar
General's estimate of population at the mid-year 1960 was 46,140.
The number of premises from which refuse was collected showed an
increase, being 14,746 as against 14,651 for the previous year.
The net cost per ton for the collection of refuse was 36/ld,
as against 33/3d. for the year ended March, 1960 and 34/6d, for the
year ended March, 1959. There was, therefore, an increase in the
unit cost per ton.
Five collection vehicles were in daily use for house refuse
collection with one other vehicle used for the most part for the
collection of butchers and greengrocers and other trade refuse. One
vehicle was replaced during the year, this being a Karrier Dual Tip
machine. In accordance with the policy of the Council tnis was
powered by a diesel engine giving a total of four refuse collection
vehicles so fuelled.
