Like previous years, the city dwellers are likely to experience waterlogging during the rainy season this time too as there is no possibility of repairing the faulty stormwater pumping machines at Rampura and Kamalapur stations anytime soon.

Engineers of Dhaka South City Corporation (DSCC) and Dhaka North City Corporation (DNCC) said it will take at least four months to make the pumping machines that were in operation in the last monsoon functional.

They also said they need to bring experts from abroad to fix the problem.

Sources said Dhaka Water Supply and Sewerage Authority (DWASA) installed the pumping machines under a project back in 2016 to save the city from the severe waterlogging problem.

Dhaka WASA recently handed over the charge of the pumping stations to DSCC and DNCC as per the government’s decision.

Engineers of DSCC and DNCC said they found two out of five pumps at Kamalapur station and two out of three pumps at Rampura station out of order which cannot be fixed without the help of original manufactures of the machines.

They also said China CAMC Engineering Company Ltd installed the pipelines while Germany-based company ABB set variable frequency drive (VFD) wiring diagram.  

Assistant Engineer (Mechanical) of DNCC Ariful Hasan said, “We’ve identified the technical glitch but we couldn’t fix it. The original manufactures can solve the problem as they know the source code of the VFD.”

He also said, “Consultancy firm Sigma is the expert body in the country to solve this kind of technical problem and we’ll engage them. They’ll hire expert engineers from the manufacturing company. But the process is being delayed due to the coronavirus pandemic.”

Ariful said the consulting agency sought four months to DNCC to start the process.

Talking to the Daily Sun, Executive Engineer of Waste Management department at DSCC Shafiullah Siddiqui Bhuiyan said they have also appointed ‘Sigma Consultancy Services’ to find out the fault. “They’ve done their field work and will submit their findings very soon. We’ll float a tender asking an expert company to resolve the problem.”

He also said it will take at least two months to complete the process of appointing a company to resolve the problem. “If there’s a major problem in the pumping machines, it’ll take 6-12 months to fix it,” he added.
