National Water denies contamination
(The New Vision, Tuesday, 15 December, 2009)
By Vision Reporter
National Water and Sewerage Corporation (NWSC) has denied press reports that city water is contaminated with sewage. William Muhairwe, the managing director, in an interview yesterday said the article completely mixed up the facts.
"The water quality report said all areas complied 95% with the national standard for bacteriological water quality." "This means that water supplied in all the towns where NWSC operates was safe from bacteria that cause diseases and there fore good for human consumption and other uses," he said.
Muhairwe also said that the quality of water was also assessed by the colour and level of clearness and transparency (turbidity) because such tests are visual indicators of the cleanliness of the water: "Most areas passed the required colour and turbidity standards," he said. The evaluation report pointed out the problem of deteriorating quality of raw water in most areas.
This has resulted in high costs of water production coming- from the use of more water treatment chemicals," Muhairwe said. He added that Biochemical Oxygen Demand (BOD) was used to evaluate the quality of effluents discharged from sewage treatment works.
It was then noted that discharge of untreated industrial and municipal wastes into the NWSC sewers from municipalities like Kampala, Mbarara, Masaka and Jinja was drastically affecting the quality of NWSC effluents.
Muhairwe said it requires extra efforts for the sewage effluents to maintain the environmental standard. The rest of the areas were reported to have performed within the limit of the environmental discharge standard," he added.
