Authorisation to proceed with the case was provided on 04/09. We attended the customer’s property on 17/09 to complete final investigations ahead of the planned repairs. Recommended repairs were authorised on 30/09. The works started on 08/12 and took 2 weeks to complete.

SATISFACTION
The customer’s dedicated Claim Technician called to confirm they were happy with the works completed. The customer was also issued with their 3-Year TankShield Warranty for our repairs.
OUR SOLUTION
Due to flooding following the storm, the Sewage Treatment Plant was found to be completely submerged. As a result the electrical systems were no longer operational.
Our CCTV survey revealed evidence of root ingress through joints within the Sewage Treatment Plant, as well as within the outlet pipework, therefore reducing efficiency.
In order to resolve the customer’s issues, we excavated and installed a new 10PE Sewage Treatment Plant with a pumped outlet.
In order to prevent future flooding, we left the Sewage Treatment Plant out of the ground and built wooden sleepers surrounding this before filling with stone.
Your Engineers did a brilliant job, thank you for all of your help.
