14. SEWERAGE AND DRAINAGE. For the most part
the drainage of the Borough is on the separate system, the surface
water going into surface water sewers which discharge into the
River Brent, the Wealdstone Brook and their tributaries and the
sewage going into soil sewers which are connected to the West
Middlesex main drainage scheme with purification works at
Mogden. Over a number of years surcharging and consequent
flooding have been experienced in times of heavy rain and the
Borough Engineer and Surveyor has submitted a comprehensive
report to the Council setting out the remedial works necessary to
give relief. The schemes will involve thousands of pounds and
it would appear that some time will elapse before they can be
carried into effect owing to stringency of the times.
There are now only four cesspools remaining in the district
and none of these receives drainage from dwelling houses; where
they do exist it is due to a sewer not being available to which
the premises can be connected. The Council's policy has been
to get rid of cesspools as soon as main drainage has become
available. All dwelling houses are provided with water closets
connected to the Council's sewers.
The Sanitary Inspectors are responsible for the testing of the
internal soil pipes of all new Council houses and reports are forwarded
to the Borough Engineer and Surveyor from time to time.
15. SWIMMING POOLS. During 1951 "break point"
chlorination was instituted at the two Swimming Pools belonging
to the Corporation, with the anticipated beneficial results envisaged
in last year's report. Algal growth was non-existent, the
water had a characteristic sparkle, and the bottom and sides of
the pools were more easily maintained in a clean condition and
free from deposits.
Bacteriological examination of the water showed that it was
up to the standard of drinking water (less than one B. Coli in
100 ml.).
The attendances at the pools were:—
16. RODENT CONTROL. The Rodent Control Service, for
which a 50% grant is obtained from the Ministry of Agriculture
and Fisheries, continued to operate. A free service is provided
to householders in respect of treatment at private dwelling houses
but in all other cases a charge is made on a time and materials
basis. Three properly trained assistants are employed on this
work and details of the work done are given in the statistical
appendix.
