Modernising Waste Throughput at Mogden Sewage Treatment Works
Updated: Sep 26
How a critical upgrade of RORO skip compactors at the UK’s third-largest treatment site ensured operational resilience and future capacity.
Project Overview: Scaling for a 60-Square-Mile Catchment
Operated by Thames Water, Mogden Sewage Treatment Works is a cornerstone of London’s infrastructure. Serving over 2 million people, the site processes up to 20 tonnes of waste daily while generating renewable energy.
To maintain its critical role in protecting the River Thames, the facility required a comprehensive replacement of four Roll-on Roll-off (RORO) skip compactors. The goal: maintain existing operations while scaling throughput to meet future demand.
The Challenge: Seamless Integration & Continuity
The project demanded a complex integration of new Thetford industrial compactors with both legacy systems and ongoing sitewide upgrades. Key priorities included:
Operational Continuity: Maintaining 24/7 sewage processing during the transition.
Robust Engineering: Delivering heavy-duty equipment capable of handling high-volume, abrasive waste.
Maintenance Efficiency: Designing a layout for rapid skip changes and simplified servicing.
The Solution: Customised Thetford Compaction Systems
In collaboration with the client and Kier Group plc , who managed the wider £66m refurbishment, we designed and manufactured a bespoke solution featuring:
High-Capacity RORO Compactors: Specifically engineered for the rigorous demands of large-scale wastewater treatment .
Bespoke Feed Hoppers: Tailored to integrate seamlessly with the site’s upgraded screening and processing equipment.
Local Control Panels: Ensuring safe, compliant, and intuitive operation for on-site teams.
Results: Future-Proofed Infrastructure
The project—spanning design, manufacture, and commissioning—was delivered successfully over several months.
Increased Capacity: The site is now equipped to handle projected population growth and higher waste volumes.
Enhanced Reliability: Robust construction reduces unscheduled downtime and maintenance costs.
Safety & Compliance: A fully integrated system layout that meets the highest environmental and operational standards.
