ActiveSG's reply ("Pool situation back to normal"; June 27) to feedback on the Ang Mo Kio swimming pool, where many lanes were being used by swim schools ("Swim schools shouldn't hog pools"; by Mr Thio Sin Lo, June 22), did not give any assurances that such an incident would not happen again.

The explanation stated that the swim schools' classes were moved to the Ang Mo Kio pool due to the temporary closure of Toa Payoh and Bishan swimming pools for the SEA Games.

If, for instance, the latter two pools were to be closed for renovation, would the classes be pushed to the Ang Mo Kio pool again?

One way to alleviate such ill feeling among public users is to allow reservation only between, say, noon and 3pm, when there are fewer swimmers around.

An additional measure would be to restrict such reservations to only two lanes. Queenstown Swimming Complex, for example, is an old and small swimming complex but, at times, has up to four of its lanes reserved.

I have also written in before with regard to over-cautiousness when it comes to lightning alerts ("Lightning alerts at public pools"; Jan 13).

Could the authorities give some feedback on the suggestion to build coverings over public pools, so that people can swim regardless of the weather?
