Water Quality

Aquatic Facilities (AF)

The National Environment Agency (NEA) regulates the quality of water in all licensable aquatic facilities with water recirculation system in Singapore, which include swimming pools, water playgrounds (including interactive water fountains) and multi-use spa pools located at all non-residential premises.


Licensing and Lab Test Results Submissions

All licensable aquatic facilities will require an AF licence to operate, under the Environmental Public Health (Licensable Aquatic Facilities) Regulations 2021 [PDF, 121.4 KB]. The definition of all 3 types of licensable AF can be found in the Environmental Public Health (Licensable Aquatic Facilities) Order 2021 [PDF, 83.93 KB].

Upon obtaining the licence, the licensee will be required to ensure that the water quality of their AF complies with the regulatory limits stipulated in the Regulations by arranging for the AF water to be tested in a testing laboratory accredited by the Singapore Accreditation Council (SAC) and submitting water quality test results to NEA at the frequency stipulated in the Regulations.

Licence application and the submission of water quality test results for the licensed AF are to be submitted online via GoBusiness. Step-by-step user guides can be found as follow:

Licensees must also maintain the cleanliness of their aquatic facilities.

Water sampling for a particular month shall be done within the same month, e.g. sampling for September shall be done within the month of September. Water quality test result for a particular month is to be submitted no later than the 14th of the subsequent month e.g. test result for September should be submitted latest by 14 October.

Updating of Licensee/ Applicant Details

Licensees should update changes in the particulars of your company or business e.g. company address, contact numbers and emails, etc. via GoBusiness (https://dashboard.gobusiness.gov.sg/login). This will allow NEA to share important notifications and reminders and reach you in a timely manner on matters such as water quality test results notifications, inspection outcomes, AF e-licence, etc. Without an up-to-date email address and contact details, the licensee will not receive these documents and information to carry out the necessary follow-up promptly.

Please refer to Page 26 of the Step-by-step User Guide on AF Licence Application [PDF, 3MB] shared above on how to amend the details.
