A committee of experts said in a report submitted in the High Court Division Wednesday that the presence of Total Coliforms and Escherichia Coli bacteria in water supplied by Dwasa indicated leakages in its distribution pipelines.
In a four-point recommendation, the committee called for the immediate replacement of Dwasa’s distribution pipelines, strengthening co-ordination and co-operation between Dwasa and the capital’s two city corporations to scotch leakages and bacteria contamination.
The four-member committee submitted the report to comply with the directive issued by a bench of Justice JBM Hassan and Justice Khairul Alam on July 30 after Dwasa and a government expert committee had submitted contradictory reports about the presence of bacteria in water supplied by Dwasa to the capital’s consumers.
The bench set December 11 for analogous hearing all the three reports.
The committee of experts recommended conducting round the year monitoring of Dwasa supplied water throughout the capital by Independent Third-Party.
In the recommendations the committee called for providing financial and technical support to the Independent Third Party for monitoring the water quality.
It called for launching campaign to sensitize the consumers to regularly clean up the underground and overhead reservoirs at their homes.
They said that Dwasa should take step to prevent illegal connection and pilferage to keep the distribution network safe and free from external contaminations.
In the previous report, submitted in the court, Dhaka University microbiology professor Sabita Rezwana Rahman, icddr,b physician Munirul Alam, BUET professor Badruzzaman and local government division additional secretary Zahirul Islam said that they had found faecal coliforms and E coli bacteria in unacceptable levels in samples of water supplied by Dwasa six of them were collected from four ground water distribution zones and two samples from the surface water treatment plants of Dwasa at Saidabad-1 and Chandnighat.
After Dwasa said that it found no bacteria in samples of water supplied to Patlakhan Lane, Lalbagh to Kalyanpur, the bench ordered the four-member committee to submit their opinions on the issue with their findings.
Dwasa said that excessive chlorine was found in surface water as it was treated with chlorine to free it from bacteria.
The test of water was conducted at laboratories of icddr,b BUET and DU as directed by the HC while hearing a public interest litigation writ petition filed by Supreme Court lawyer Tanvir Ahmed.
The petitioner submitted that 80 per cent of tap water across the country was contaminated with E coli bacteria.
He also submitted that he got the information from a World Bank study report.
