Cambridge water tank finally out of service after leaking for years

A leaking tank is to be taken out of service by Cambridge Water after losing millions of gallons over the last few years.

Cambridge resident Marc Tucker and wife Catherine estimate that the tank, situated between Longstowe and Gransden next to the B1046 and opposite the Hayley Wood nature reserve, has spewed out 2.5 million gallons over the last five years.

A willow tree is also growing out of the side of a pipe some 15 feet above the ground.

The water company has finally decided to take the tank out of operational service, although it says there was no contamination of its drinking water.

Ciaran Kelly, head of operations at Cambridge Water, said: “We are aware of a minor leak in the tank of Longstowe Tower, which contains clean ‘potable’ water and is safe for the surrounding wildlife.

“Due to the size, age and material of the tank, the leak is difficult to repair. There is also tree growth in the insulation of the exterior skin of the tank, not in contact with the potable water, but the removal of the tree would be difficult based on its location and while ensuring the integrity of the tank.

“We have therefore carried out a number of inspections and assessments in order to decide on the best course of action, and have taken the decision to bypass the tank and to remove it from service. This will require some modifications to our network and an upgrade to a booster station. We are currently in the construction phase of the booster upgrade and aim to complete the work within the next few months, prior to testing the system to ensure integrity of supply to our customers. We appreciate help from our customers and members of the public by reporting any bursts or leaks they spot.”

Mr Tucker said: “The pipe has been leaking for at least five years which means more than 2.5 million gallons have been wasted, but at least a willow tree has benefited.”
