SINGAPORE: The skies were grey and the roads were slick, but Mr Subramaniam Pavaday was on the move.
“If it is a choke, we need to accept that our line has been choked. If not choked, we just tell them it’s not choked, it’s only because of the nonstop heavy rain.” To allay the concerns of the home owner, Mr Subramaniam promised to do additional checks of the sewer line in future and conduct cleaning if required.A PUB veteran of more than 40 years, Mr Subramaniam joined the company on the urging of his father, who was working for PUB and repaired pipes.
“We opened up the manhole near the Mustafa . We needed to clear the grease, and we saw the python sleeping there. We immediately closed it up, called up our officers in the office and told them there is a python there in the manhole. Among other tasks, he supervises sewer cleaning, repair operations as well as inflow and infiltration detection. If there is an emergency or a surge in public feedback, he also attends to these cases.The tools used for the cleaning and maintenance of sewers are now far more advanced. To inspect sewers, workers use equipment such as borescopes which are inserted through keyholes.
Should a blockage be detected, hydraulic jetters – tools that use high-pressure water jets to dislodge accumulated grease, debris and sediments inside the sewer – are used. The water jet cleans the sewer of debris and flushes it down to the next manhole, where the debris is collected in a grit catcher net and pulled to the surface.A typical day for Mr Subramaniam is usually spent on the go. Along with his crew, he has a list of sewers to inspect.
