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.
