Hello everyone. In this update, I want to tell you about some reinstatement work we did at the Croft's Lane play park. Our site teams worked with Northumbrian Water to "give something back" to the local community.

We worked with Horsley Parish Council and our neighbours. We removed the debris and soil from the north east quadrant of the play park.

We levelled the topsoil and seeded the area.

We replaced a section of timber post and rail fence after the reinstatement works were completed.

Hello again. In today's update, I want to concentrate on one particular aspect of our works. That is checking the integrity of larger diameter underground pipes using CCTV surveys.

We used this piece of equipment to survey the inside of the new pipelines before we tested and commissioned them. It is a remote controlled CCTV unit.

The CCTV unit operator gets a real time view of the inside of the new pipes. The operator will check the integrity of the pipe and note anything of interest.

We checked all of our new pipes and all the pipes are ready for testing and commissioning. This is a major milestone in this project.

The testing of the pipes is progressing very well. We will be commissioning the pipes next. The site team has done very well to get the large diameter pipes ready to transport water.
