Tanjong Pagar residents will find students knocking on their doors to spread the message of being gracious and the importance of keeping their estate clean.

This is part of a move by the Tanjong Pagar Town Council to improve on the cleanliness of the neighbourhood. The campaign, called "Gracious Living in a Happy Block", will cover 50 blocks which have been selected based on feedback from residents.

According to a survey conducted by the town council last year, these blocks are the most "anti-social" blocks, which means that there are incidents of high-rise littering, dumping of items along common corridors, among others.

Dr Lily Neo, chairman of the town council, said at the launch of the campaign on Sunday: "Seeing a tremendous increase of mosquito hotspots in our tropical country and the recent haze, the need to bond as a community and work together for a clean and safe haven we can rest in and call home is even more evident now."

So far, two schools - Outram Secondary School and Radin Mas Primary School - have partnered the town council to engage students as "cleaning ambassadors". These students will go around the blocks with brochures once a month to speak to residents.

In addition, the town council has also added surveillance cameras in all the lifts of the 50 blocks. Cleaning schedule is also changed to the evening instead of afternoon, so residents can come home to a cleaner environment.
