Case Studies

Affinity water, Mains burst on reservoir feed.

Affinity Water identified a visible mains burst on 42” raw water main feeding a reservoir that distributes water to over 200,000 customers.   The reservoir can last up to 48 hours once isolated to facilitate repair; time is of the essence as  the Water companies face harsh penalties when customers experience an interruption to supply.

The Challenge

CLC Utilities team in PPE stood at the top of a trench with CLC branding in front of them

As a trusted partner of Affinity water, CLC were contracted to locate, repair, and reinstate the mains supply without Affinity facing compensation penalties. 

CLC's track record and experience was seen as a key differentiator to meet the logistical and time sensitive challenges of the project.

The Solution

As well as a full site set up, location of issue, fix and reinstatement, CLC had to design and fabricate a bespoke component all within 48 hours.

The need to deliver the project at speed and to high standards were paramount, as The Water companies face harsh penalties when customers experience an interruption to supply, this can cost millions where performance commitments aren’t met.
