Household water charges in Scotland are to be increased from April.
The 1.6% rise across all council tax bands will mean an increase of around £6, with an average Scottish Water charge in 2018/19 of £363.
Scottish Water said it is investing in infrastructure projects across the country and that annual rates remain below the average charge in England and Wales of £405 a year.
Scottish Water chief executive Douglas Millican said: "We continue to deliver one of the best value water and waste water services anywhere in the UK for our customers, who are at the heart of what we do.
"In providing 1.35 billion litres a day of drinking water to communities, our customers benefit from investment in the network required to bring that to their taps, ensure it is safe to use and is as fresh and clear as possible.
"They are also benefiting from our over £3.5 billion investment in water and waste water infrastructure which will safeguard supplies for many years to come."
