Water companies will increase the average annual water and sewerage bill to rise by 6% in England and Wales from April, according to its trade body.
In Scotland, water and waste charges will go up by 8.8%, said Water UK.
David Henderson, Water UK chief executive, said the rises would help pay for more than £14.4 billion of investment in the next financial year, the highest annual amount on record he added.
On average, that will mean a bill in England and Wales for water and sewage rising by £27 to 473 a year, while Scottish users will pay £36 a year extra.
Sewage dumping by water companies in rivers and coastal waters has become a national scandal and under duress, the industry has submitted proposals to increase bills by an additional £156 a year to 2030 to pay for remedial work to reduce discharges.
Infrastructure spending would almost double to £96 billion if Ofwat allows the plan, Water UK said.
From April, Wessex Water and Anglian Water will have the highest average bills at £548 and £529 respectively, with Northumbrian customers will see the lowest average bills of £422.
