Good Afternoon,

I would like to take this opporunity to thank the Parish Council Committe in allowing me and Mike Foster (NWL Project Manager) attend their Parish Meeting last night. 

Just to let you know we will be in touch to invite you to a coffee morning in October to give you an update and progress on the programme of work at the Water Treatment Works. 

It will give me the chance to meet some of the residents and introduce Mott MacDonald Bentley as the new contractor in a less formal format. 

I will confirm the date/time in due course and if you can come along even just to have a cuppa and a cake it will be good to see you.

Thanks

Joan

Good Afternoon,

I just thought I'd show you a couple of snap shots taken by the team to demonstrate how "Table Mountain" (as we have nicknamed it) has started to deminish. Whilst we won't remove it entirely we have made progress in it's appearance.

A couple of weeks ago we were approached by a couple of residents who were at a loss as they needed a plinth built to sit a beautiful park bench to commemorate a neighbour. We obviously jumped at the chance for such a fantastic cause.

Have a look at the photos.

Don't forget to ask me any questions you may have and if you forget I thought I'd let you know Mike Foster (NWL Project Manager) and I will be attending the parish meeting on 20th September.

Hello everyone. In today's update, I want to concentrate on the works we are carrying out next to one of the water main in the south east quadrant of the Horsley site. We are carrying out piling operations before we start on the connection works.

We have designed and constructed a piling platform. This is to take the weight of the piling plant and equipment when we start constructing the piles. This platform will also take the pressures the piling plant and equipment will impose on the ground. The piling platform is constructed from well compacted granular material laid on top of a geogrid support. 

To construct the concrete pile, we will be cutting through clay, augering through the sandstone strata and drilling through boulders. The equipment we will be using is powered by compressed air. The plant to generate this pneumatic power has been set up on site next to the works area.

We carried out pre-start ground investigation surveys to determine the type of ground present at the piling location. Our team is prepared to auger and drill trhough the different types of ground that we expect to encounter. This photo shows the augers that are used to drill through cohesive material.

Our site teams are monitoring noise levels and vibration levels at the works area and at the site boundaries. There are no concerns regarding noise or vibration. Our site operations are progressing well. We have constructed several reinforced concrete piles and we expect to finish our piling operations in line with our programme.

The filter tanks at the Rapid Gravity Filters building are complete. The structures are complete, the steelwork has been fitted and the beds are in place. Our commissioning teams have started the testing and commissioning works at these filters.

Our electricians are making good progress with the installation of internal and external lighting. This photograph shows the new lighting at the western boundary of Horsley water treatment works. 

We have installed a lot of specialist water treatment equipment on site. This photograph shows some of this specialist equipment that have been connected to the new treatment plant.

The below ground works are nearing completion and our site teams are progressing with the construction of the roads and hard landscaping.
