As we approach completion of our project at Lower Penn site, 90% of the works are now complete. At the heart of the project, we have constructed a 15m diameter, 13m deep shaft along with a 3-way valve chamber, interceptor tank, inlet chamber, flow meter and an MCC to control the system. The shaft will store contents that will be pumped 2km along into a storage tank at Warstones Pumping Station where we are installing a 230m3 SDS wheolite storage tank and making 1 No. connection into an existing sewage pumping station at 5m below ground level.

To support access and infrastructure, an access road leading to the nitrate dosing rig and a vegetated retaining wall have been built. The retaining wall will be hydroseeded in the coming months to enhance sustainability and environmental integration.

Some key highlights of the project include successfully welding and installing the SDS tank, ensuring the smooth progression of the works. However, the team also had the challenge of tackling the unforeseen groundwater, whilst working in a small area. Through problem solving and careful planning, the team were able to mitigate the issue and continue the works as planned.

Sustainability continues to be a focus as we work towards reducing our carbon footprint on all our projects. One of the things we were able to do was to have some of our compound stone collected by a local quarry for regrading and to be reused delivering both environmental benefits and cost savings to the project. Furthermore, at Warstones local park, we have effectively minimised disruption to the surrounding community. Our site management has been exceptional and our team continues to showcase our dedication to fostering positive community relations.

A key lesson learnt on this project was using a large 75mm stone beneath the SDS tank, creating a clean and dry working area. Using this approach meant that when the tank was delivered, it could be fitted straight into position, preventing unnecessary exposure to dirt and potential damage. This method has proven to be both time efficient and a protective measure that can be applied to future installations.

Well done to the entire team for their hard work in delivering this vital project.
