Partial water changes help maintain pool sanitation, ID says

In reply to lawmaker Zheng Anting, the Sports Bureau (ID) made assurances that partial water changes and regular cleaning are among ways to maintain swimming pool sanitation.

In his written inquiry, the lawmaker asked the bureau to disclose how water sanitation is maintained in public swimming pools, amid the arrival of swimming season.

In addition to the aforementioned methods, ID president Pun Weng Kun stated that the bureau also relies on the water circulation system to sanitize the water. Regular maintenance of the water circulation system is also conducted, in addition to regular complete water changes.

Health Bureau (SSM) standards on free chlorine residual levels are also observed during the sanitization process. Regular ‘top-to-bottom’ major cleans will also be undertaken every year.

Pun said that the bureau will also increase the frequency of water sampling and inspection in accordance with the popularity or other pool conditions. Tests are conducted on water temperature, pH values and free chlorine residual levels to strengthen water quality monitoring.

Regular water sampling is conducted twice per month at swimming pools in use, Pun added. All the test results are uploaded to a specific website of the Municipal Affairs Bureau (IAM).

On the other hand, Pun assured that the ID had been keeping an eye on new releases of swimming pool sanitation systems or products to upgrade existing facilities “while meeting spatial and financial requirements.” He added that no such upgrade has been planned for the time being.
