31. WATER SUPPLIES AND SEWAGE DISPOSAL
WATER SUPPLIES
The whole of the Borough is fortunately supplied with mains water, there being
four public sources. The Colne Valley Water Company supplies small parts of
Perivale and Horsenden Wards. The Rickmansworth and Uxbridge Valley Water
Company supplies the remainder of Perivale and Horsenden Wards, part of Waxlow
Manor Ward and the whole of Ravenor, Mandeville and West End Wards. The
South West Suburban Water Company supplies the whole of Dormers Wells and
Northcote Wards, the remainder of Waxlow Manor Ward and part of Glebe Ward.
All other areas of the Borough not already mentioned are supplied by the Metropolitan
Water Board.
These public supplies are not subject to plumbo-solvent action and have been
satisfactory both in quantity and quality. Water from public mains was supplied
to 88,901 dwellings with a mid-1965 estimated population of 303,660.
Thirty-six samples for bacteriological examination and chemical analysis were taken
from private supplies derived from wells at 11 factories in the Borough. In these
factories, water is obtained from deep borings ranging in depth from 300 to 600 feet.
Of these 36 samples, one proved to be unsatisfactory but, after thorough cleansing
and sterilization of supply pipes, repeat sampling proved to be satisfactory.
Forty-eight samples of tap water from public supplies were taken, of which 15
were unsatisfactory. In most of these cases, storage tanks had become contaminated
and all were thoroughly cleaned and properly covered. Satisfactory repeat samples
were obtained when all necessary works had been completed.

SWIMMING BATHS
The Council is responsible for the maintenance of four indoor public swimming
pools at Ealing, two indoor pools at Acton and one outdoor pool and a paddling pool
at Southall. In addition, there are swimming pools at four Education Department
schools in the Borough for which the Council is now responsible and at one direct
grant school. A private outdoor swimming pool is operated by a local industrial
firm at its sports ground at Greenford.
Samples of water from each pool were taken by the Department at regular intervals
when they were in use, and were submitted for bacteriological examination.
From
a total of 346 samples, 12 were found to be unsatisfactory, but further samples taken
