The rise for 2014\/15 is below inflation and will see the average water bill rise to £128.90 from £127.18. The company, which serves St Ives and some eastern areas of Huntingdonshire, said its charges the second lowest bills for water in the country were 31 per cent lower than the national average of £188. Customer service director Rachel Barber said: We know that our customers expect us to provide a high quality service at the lowest possible price. So, once again we have worked hard to keep our costs down. On average, the tap water we provide is under 35p a day. The firm added that the increase was necessary as it would help fund a £39million investment plan during 2014\/15. Anglian Water provides the wastewater services for Cambridge Water customers and a charge for this is added to the bill.
