Safety regulations surrounding our lovely pool are very stringent indeed!, and we should know as we were very heavily involved in setting the Social Services safety standards for swimming pools in private nurseries.( Which is not that unusual when you realise that we are the only nursery with a swimming pool!! ) The pool is situated in a giant inflatable dome and measures 36 ft by 18 ft and is of course heated. Children (and babies) use the pool throughout the summer months without any tears. The water contains no chlorine. ( The water is kept crystal clear biologically ).
