Description

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.

To ensure all waste streams are fully serviced, we have implemented the lotting structure set out below:

• Lot 1a - Screenings & Grit (Grab-Lorry)

• Estimated annual volumes: 19,500 - 23,500 tonnes

• Lot 1b - Screenings & Grit (Skips)

• Estimated annual volumes: 11,000 - 15,000 tonnes

• Lot 2 - Ash

• Estimated annual volumes: 4,500 - 5,000 tonnes

• Lot 3a - Metals

• Estimated annual volumes: 500 - 700 tonnes

• Lot 3b - Hazardous

• Estimated annual volumes: 120-150 tonnes

• Lot 3c - Multi-Waste

• Estimated annual volumes: 5000-5500 tonnes

Please note: There will be no limit on the number of lots a supplier may be awarded.

Thames Water reserves the right to refine the award criteria.

Please note that that deadline for asking for access to the PSQ & submitting of the PSQ is 28th August, 2026 at 12 noon.
