My water is discoloured – what can be done?
In Scotland, most untreated (raw) water from sources where it comes into contact with the land can be coloured. The intensity of the colour can vary depending upon the season and level of rainfall. Every effort is made to reduce the colour caused by the dissolved organic matter in all the water treated at Scottish Water’s water treatment works. However, some of the treatment processes used, like slow sand filters, are not as efficient as others at reducing colour in the water. Therefore, occasionally, some colour remains in the treated water and you may notice this in your water following heavy rain in your area. This colour could range from yellow to brown. Your water is safe to drink. A burst water main can also cause some discolouration and can be resolved by running your cold water tap until the water runs clear.
