Some of the pipes supplying Alnwick are up to 80 years old and are therefore, not as reliable as they were. Improvement work started on 3 May 2005 and is expected to last for up to eight months, with a total of 26 kilometres of water main being upgraded, at a cost of £2 million.
Supplies to the population of Alnwick, around 2,000 people, will be directly improved - and the project will also benefit its many thousands of visitors.
To try to minimise disruption as much as possible, during busy periods, we have avoided work in the town centre over the Alnwick Festival and Christmas periods.
Contractors working for Northumbrian Water will gradually work through Alnwick, renewing or relining the old iron main.
Some of the pipes have furred up and, although not harmful to health, this can restrict the flow and reduce the volume and pressure of water in the mains. Old pipes can also lead to harmless discoloured water when sediment is disturbed.
Water quality and flow will be improved, leakage will be reduced and a more robust system will be in place, to safeguard supplies for future generations.
