Beanfield Water Towers – Corby

Structural survey, strength investigation and condition survey to two water towers owned by Anglian Water

❯

The challenge

The two Beanfield Water Towers at Corby were built in the 1960s and 1970s respectively. Number 1 holds 1.14 million litres whilst the larger Number 2 holds 3.41 million litres. The towers are part of an Anglian Water network which links Rutland Water to the Beanfield Reservoir and Water Towers via the Morcott and Wing Water Treatment Works. The treated water then flows into Hannington Reservoir in Northampton.

Engineering Consultancy

Anglian Water identified that some of the water towers’ roof drainage pipework needed rerouting to reduce risk of untreated water entering potable water tanks in the event of drainage pipe leaks. Principal Contractor Stonbury appointed Inertia Consulting Ltd to carry out the required survey, investigation, options study and detailed design of the new pipework route.

“Very good, efficient, helpful and very in depth services offered and to a very high quality and standard.”

Paul Dart, Contracts Manager, Stonbury

The project involved a full structural survey and investigation to assess the condition of the structure and ascertain an appropriate route for the new pipework which would not weaken the structures. To prepare the design we undertook strength testing, cover and dimensional surveys, and a full conditional survey. The non-destructive testing methods used included concrete coring for strength testing purposes and a full hammer visual survey of the tank structure.

During the works, our engineers used their expertise and experience in confined space working and rescue to ensure team members’ safety and comply with HSE requirements.

The outcome

The project was completed successfully. Residents in the Corby area can continue to enjoy a supply of safe drinking water from the towers for years to come. Our structural investigations also reassured our client that the water towers were in a good state of repair.
