Maintenance Treatment for Rats in Sewers
I am indebted to the Borough Engineer & Surveyor for
details of the treatment of sewer infestations which are dealt
with by his staff.
These treatments are normally carried out at six-monthly
intervals during April and October, During 1958 it was not
possible to commence operations until late May and early June.
The second treatment due November/December, was for reasons of
staff shortage and pressure of other work, impracticable and
consequently postponed until early 1959.
For the treatment carried out the poison medium was
arsenious oxide 10 per cent, in sausage rusk with the addition
of 0,25 per cent. paranitrophenol as a preservative. Details of
this operation are as follows;-
Manholes baited 746
Manholes showing prebait take 296
Manholes showing complete prebait take 56
Prebait take was in the region of 40 per cent., a
slight increase over 1957. Complete takes were also increased,
a factor most likely due to the better keeping quality of the
bait induced by the addition of the preservative,
YALE OF HEAUH PRIVATE FAIRGROUND
Sanitary Conveniences
It is pleasing to record that, at long last, the
"Clochemerle" episode at the Vale of Health fairground is now
closed, I am not sure whether the sanitary structure evolved
is really worthy of the efforts made by the Department over a
period of nearly ten years, but it appears to be all the owners
are prepared to provide,
The history of this case makes almost fantastic reading.
In the summer of 1949 it was reported to the Public Health
Comnittee that the toilets at the fairground were in a "blitzed"
and derelict condition and we were instructed to press for their
reinstatement. Prolonged negotiation ensued and finally plans
of new conveniences were deposited and approved. So far, so good.
The owners then apparently came to grief with their war damage
claim and found themselves unable to proceed with the project.
