Project Description

The £80 million upgrade of Slough Sewage Treatment Works for Thames Water will be carried out by Ferrovial Construction and Cadagua, working together as a joint venture. This project aims to improve the resilience and sustainability of Slough STW, ensuring it meets tougher Environment Agency standards and achieves better environmental performance. Improvements include expanded treatment capacity, advanced systems for removing ammonia and phosphorus, upgraded storm-flow management, and robust new power infrastructure. The partnership combines Ferrovial Construction’s expertise in UK infrastructure projects with Cadagua’s broad experience in international water treatment.
