However, the water sample taken on the same date after treatment by water and sanitation agency (WASA), was analyzed at NWQL, PCRWR and found fit for human consumption, an official of PCRWR informed to media.
The raw water always has contamination of water which is being treated before distribution, a spokesperson of PRCWR informed when asked. She said solid waste, germs, bacteria, micro biological contaminations and solid waste management are found in lake water.
But the water is being treated properly through purification plants removing all impurities making it fit for consumption then distributed to the capital city.
However, she added there is a dire need to educate people not to throw solid waste in the streams and the water entered into the lake should be treated before adding it to Rawal lake for securing aquatic life and health of people from nearby communities who use the untreated water for swimming or washing purpose.
