Waste Management

Thames Water is the UK's largest water and wastewater service company. Every day we supply around 2,600 million litres of tap water to 9 million customers across London and the Thames Valley.

We also remove and treat more than 4 billion litres of sewage for 16 million customers. In everything we do, we follow Thames Water's purpose and values.

Our operations generate significant volumes of waste, particularly material and grit removed from customer and council wastewater. This represents the largest waste stream across our sites, and recycling is prioritised wherever possible over landfill.

At Beckton Sewage Treatment Works in Barking, London-one of our largest sites-we operate an incinerator to process biowaste. This produces ash as a by-product, which is currently collected and all ash collected from the silos is recycled.

In addition, our sites generate construction waste, recyclables, metals and hazardous materials, all of which require reliable collection and safe disposal to ensure continuous operations. We are seeking dependable, innovative partners to support approximately 150 sites, keeping them running efficiently while developing alternative re use solutions to minimise landfill dependency.
