So far as Hampstead was concerned it was suggested that two stations
should be provided, the apparatus at each station to consist of
(i) a deposit gauge (similar to a rain gauge) for recording pollution
by ash or grit and (ii) a lead peroxide instrument for recording the
activity of sulphur dioxide in the atmosphere in attacking the fabric
of buildings.
The sites selected for the stations were: the Hampstead Cemetery,
Fortune Green Road, and the Metropolitan Water Board Reservoir, Barrow
Hill. The installation was completed by the end of the year, and it
was arranged for readings to commence on the 1st January, 1954.
EMERGENCY WATER TANKS
The problem of nuisance arising from disused emergency water
tanks has received much consideration and it has been decided that
the maintenance of emergency water tanks will now rank for civil
defence grant. The responsibility for maintaining the tanks in
London is that of the London County Council, but the local Borough
Councils have agreed to act as agents for the cleaning out of the
tanks.
The tanks on the following sites were cleaned out once during the
year by the Borough Council, the cost of £485 being reimbursed by the
London County Councils
177 Adelaide Road
86 Adelaide Road
Carlingford Road and Willoughby Road
63 Fitzjohns Avenue
20 Lindfield Gardens
47 Greencroft Gardens
1 Belsize Road
Kilburn Priory and Springfield Lane
Sumatra Road.
Special inspections of the tanks were made to ascertain whether
it would be possible to drain the tanks into existing intercepting
chambers, but in only one case, Sumatra Road, was it found possible,
and the London County Council agreed to make arrangements for this work
to be carried out.
THE RAG FLOCK & OTHER FILLING MATERIALS ACT. 1951
Only one firm has been registered under this Act.
The premises of many other firms have been visited but in each case
the work only concerned repair and reconditioning and did not therefore
come within the purview of the Act.
No samples of filling materials have been analysed during the year.
