Watch mock sewer clearance and inspections by robot

They are among activities for Go Green SG, which starts from June 2

Rags, hardened grease, sanitary pads, condoms and wet wipes these are some common culprits that cause sewer choke, resulting in odours and overflows.

Though the natural instinct is to get as far away as possible, PUB's first response team attends to the blockage as soon as it can upon receiving reports from the public.

Using metal rods that can be fitted to extend up to 100m, the team can reach into the sewer and hook onto obstructions with a spiral auger to clear the sewer.

In July, the public will be able to watch the team carry out a mock clearance of a sewer at PUB's Waterhub. This is followed by a guided tour of the nearby Ulu Pandan Water Reclamation Plant, where participants can learn how raw sewage is turned into clean, drinkable water.

PUB engineers will also demonstrate how a remote-controlled closed-circuit television robot is used to inspect sewers for defects and blockages.

These are among the slew of activities that will be part of Go Green SG, an annual movement led by the Ministry of Sustainability and the Environment (MSE) to rally citizens, organisations and the community to make Singapore a green, liveable and climate-resilient nation.
