20 May 2017 - The greenest PTA Summer Fair ever! The PTA showed their commitment to sustainability by having water refill stations instead of selling plastic water bottles, and also ordering 'cornware' disposable plates and cutlery for the food stalls. They even designed and produced a Tanglin-reusable water bottle!
