After nearly two years of dedicated work, a major £11 million refurbishment project at Somerset’s Langport water recycling centre has been completed. This large-scale upgrade aims to safeguard the health of the River Parrett and surrounding waterways by significantly reducing harmful chemicals in treated wastewater.
The project, finished in May, involved extensive improvements to the ageing treatment facility in Langport, located near the heart of Somerset. Over an 18-month period, Wessex Water and its engineering partner YTL Construction enhanced the site’s capacity to remove phosphorus and other damaging nutrients from wastewater.
Key upgrades included the installation of new treatment systems, additional large tanks, modern electrical equipment, and the movement of more than 8,000 tonnes of earth to facilitate these improvements. These measures ensure the treatment plant meets stringent environmental targets and continues to produce high-quality effluent, benefiting the River Parrett’s ecosystem.
Project manager Victoria Plummer explained the importance of tackling nutrients like phosphorus, which enter waterways from sewage, agricultural fertilisers, farm slurries, and septic tanks. “Excess phosphorus can trigger excessive algae growth, a process called eutrophication, which depletes oxygen in the water and harms aquatic life. This project is part of Wessex Water’s commitment to reducing these impacts and preparing for future population growth.”
This effort is part of a broader programme throughout Somerset, with over £40 million invested in upgrading water treatment facilities near Martock, Crewkerne, Merriott, and Somerton. For example, a £5 million enhancement in Somerton has improved chemical removal to protect the local River Cary.
Looking ahead, Wessex Water plans to begin constructing a £5 million integrated wetland near Shapwick next summer. This natural solution is designed to further reduce nutrient levels in runoff before it reaches rivers.
Additionally, the Competition and Markets Authority (CMA) is reviewing Ofwat’s final determination of Wessex Water’s 2025-30 business plan. If approved, this will enable an £820 million investment package focused on water quality improvements, including removing 1,550 tonnes of nutrients from regional waterways through upgraded infrastructure.
Together, these initiatives demonstrate a comprehensive, long-term commitment to preserving Somerset’s rivers and aquatic life for generations to come.
