Thames Water – UK
“We’re exploring robotic sand filter cleaning with the SSF-800 to maintain water output while minimizing labor and downtime.”
— Maintenance Planning Lead, Thames Water
Thames Water is the UK’s largest water utility, serving over 15 million residents and managing extensive infrastructure including reservoirs, treatment plants, and pipelines. The utility regularly contends with sediment buildup, algae blooms, and aging concrete linings in tanks and basins. These challenges can compromise flow rates and water quality if left unaddressed. Thames Water has adopted robotic cleaning technology to reduce reliance on manual labor, avoid draining assets, and meet evolving environmental regulations. This technology helps improve customer service reliability and extend asset lifespans.
The Challenge
Manual skimming of slow sand filters created bottlenecks in treatment operations, required high labor input, and could not be performed on demand.
The Weda Solution
Thames Water initiated a pilot with Weda’s SSF-800 robot — a surface skimmer designed specifically for slow sand filter maintenance. The unit allows on-site, instant cleaning with minimal disruption.
