Further samples were taken from a stream in the North
Greenford area which was the subject of complaints in 1949 and
the results of the analyses indicated that the steps taken by the
Authority through whose area the stream passes prior to entering
Ealing had been largely successful in eliminating contamination of
the stream by sewage.
Drainage and Sewage.
Three houses previously connected to cesspools were connected
to the Council's sewer during the year. At the end of the
year arrangements were in hand for a further two houses to be
connected.
There are now only 28 permanent houses in the Borough
not connected to the Council's sewers, of which 18 are in the
Northolt Ward.
Atmospheric Pollution.
140 Smoke observations were made by the Sanitary Inspectors
and in 5 instances it was necessary to make representations regarding
the emission of black smoke.
In one instance the heightening of the boiler flue and the use
of a better quality fuel succeeded in abating the nuisance. In two
other cases improved methods of stoking effected an improvement
and no further complaints were received. In another instance a
temporary improvement was effected by the use of a better quality
fuel but this was not wholly successful and at the end of the year
other steps were being taken to abate the nuisance.
In a further case, that of a large factory with oil burning
furnaces, numerous complaints were received regarding the
emission of sooty particles from the boiler flues. The Chief
Sanitary Inspector and the District Sanitary Inspector concerned
attended a meeting at the factory at which were also present
representatives of the firm, representatives from the boiler manufacturers,
and from the London Coal Tar Fuel Committee. As a
result of this meeting measures were taken to improve the system
of pre-heating the oil before it enters the furnaces and this was
successful in abating the nuisance.
Numerous complaints were also received regarding fumes given
off from a yeast drying process in the Hanwell area. The management
of the factory engaged a firm of specialists to instal an
extraction and condensation system in an effort to abate the
nuisance. At the end of the year a considerable improvement
had been effected but adjustments were still being made to the
plant in an effort to effect a still greater improvement.
