The water supplied in this Borough is not subject to plumbo-solvent
action. Bacteriological, chemical and radio-activity tests of the
water are carried out as a matter of routine by the Board and the
results of these tests are regularly forwarded to the Council.
No complaints were received during the year as to either
quantity or quality from any of the occupiers of the estimated
45,529 dwellings in the Borough.
In addition to water supplied to them by the Metropolitan
Water Board, local industries take water for industrial and firefighting
use from seven wells which are still in use in the area.
Well water is also used at the Council's swimming baths at
Woolwich and Plumstead. Samples of well water taken for bacteriological
examination showed that the water was satisfactory.
DRAINAGE
Drainage defects found during the course of 1963 totalled
445, and the work of repair or reconstruction was supervised by the
Public Health Inspectors. A total of 58 private or combined drains
were tested with smoke, and of this number 22 were found to be defective.
Of the defective drains two were subsequently discovered to be disused,
and they were accordingly exposed and sealed off by the Health Department
staff.
Two of the 28 combined drains tested were found to be defective,
and the necessary repairs were carried out by the responsible owners.
PUBLIC BATHS AND SWIMMING POOLS
Water used in the Council's swimming baths is continuously
filtrated and chlorinated, and samples from paddling pools as well as
the swimming baths are taken regularly for testing.
Samples of water were submitted to the Southern Group Laboratory,
Hither Green Hospital for bacteriological examination, and further
samples of the water were tested by the Health Department staff for
chlorine content and pH reaction.
