Swimming baths
There are 4 public swimming baths in the borough, in addition to
a few club and school swimming baths. The public swimming baths are
shown in the table, together with the laboratory tests taken during the
year.
Table 16
Bath | Tests | Variation of chlorine (p.p.m.) | |
---|---|---|---|
Chlorine | Bad. | ||
Ladywell West | 9 | — | 0.1—2.0 |
Ladywell East | 9 | — | 0.1—1.4 |
Forest Hill North | 3 | — | 1.1—3.1 |
Forest Hill South | 4 | — | 0.4—3.3 |
Downham | 7 | — | 0.1—1.7 |
Bellingham (openair) | — | 0.05—0.1 |
The water used for these baths is supplied by the Metropolitan
Water Board and is sterilised by the breakpoint chlorination method,
sodium carbonate and sodium metaphosphate being used to control
acidity and to keep the pH above 7.2. Colorimetric tests for free chlorine
and pH value are also made at the baths at 9 a.m., 1 p.m. and 6 p.m.
on weekdays and at 9 a.m. and 1 p.m. on Sundays, the results being
recorded on log sheets kept for the purpose. The aim is to achieve a
circulation of water every four hours, although it is rather more prolonged
than this at the openair baths.
