Refuse Collection and Disposal.
The collection and disposal of house refuse in the area
is carried out by direct labour, and some delay in collection
occurred during the early part of the year due to extremely
adverse weather conditions. Later in the year it was possible
to maintain the period between collections at approximately
one week.
Three newS. & D. Freighters were delivered during theyear,
and a further three placed on order. The new freighters
eased the transport position to a certain extent, but, until it is
possible to dispense with the older vehicles, there is always the
risk of delay in collection owing to mechanical breakdown.
The collection of salvage was continued during the year,
and the income from sales of materials amounted to £2,485.
There are approximately 400 bins in the streets for the reception
of kitchen waste and these are cleared twice weekly.
This waste is disposed of at the concentrator plant in the
Woolwich area. House and trade refuse collected in the area
is disposed of by controlled tipping.
