Two new Archimedes Screws have been installed at Margate Wastewater Pumping Station in Kent.

As part of the £9 million project, the new arrivals replace existing mechanisms which were almost 40 years old.

They help defy gravity by lifting the sewage from North Thanet from the sewer to the start of the treatment process.

However, as they're often in action 24 hours a day, even the largest ones start to wear in time, which effects the efficiency of pumping stations, and mean they eventually require replacing.

Project Manager, Jonathan Yates, said: "New Archimedes Screws are vital to Margate Wastewater Pumping Station running efficiently and effectively. It was important that they were replaced as part of the increased resilience works underway to ensure a robust and efficient way to move and treat the sewage."
